My wife has the S8 and I have the S8+. After the latest update (July 9-10'ish) both of our phones are having problems with our Mesh WiFi, but not our non-Mesh WiFi. We don't have issues with the connectivity to the actual WiFi, that always stays connected, but every few minutes, we'll get an exclamation point next to the WiFi signal meter, and our Internet connectivity drops. When I check WiFi connections during this time, it shows "Internet may not be available". Then, after 1-3 minutes or so, it's working fine again. While this is happening, none of our other devices have any problems with Internet connectivity.
T-Mobile had me boot into Safe Mode, and the problem didn't happen at all in safe mode. So, I did a master rest, and with just factory apps installed, it was happening again. T-Mobile asked me to wipe the cache partition. While trying to boot to that menu, my phone went into a boot loop, then after trying several different button combinations, it just turned off and wouldn't power back on again. So, T-Mobile sent me a replacement. Since receiving the replacement, I have not installed the update, and I have not had the problem on my phone at all. But, there's still my wifes phone. T-Mobile tells me I'm the only one having this problem, so they don't know what the solution is.
Our Mesh WiFI system is fairly new, so I kept the old WiFI active as a fall back option. There are no problems when connecting to that SSID, so I'm thinking the update has caused some issues when jumping between access points on the mesh system. I was also thinking maybe it's a double NAT issue, since my modem doesn't have a true bridge mode option. (My modem hands my mesh WiFi router a 192.168.1.xxx IP, but my devices that connect to the mesh WiFi get a 192.168.0.xxx IP) I tried putting the Mesh WiFi in the DMZ and making sure it gets the public IP. That didn't work. The WiFi manufacturer had me open ports 500 & 4500 to the WiFi router. That didn't work.
Does anyone have any other ideas for me? At the point, T-Mobile is telling me that it's my WiFI because it doesn't happen when connected to the non-mesh WiFi. But, it didn't start happening until the last update, and it's not happening on my replacement phone. We rely very heavily on WiFi calling, so this has been problematic. Obviously I can connect my wife's phone to the old system, but we don't get full coverage in our house from it, which is why we went to a mesh system.
I welcome and appreciate all suggestions.
Thank you

I have the same problem with my non-mesh Google Wifi router occasionally. it's annoying.

I'm having the same exact problem with my S8+ and my netgear orbi, all was good until about a month ago, and I've tried pretty much everything, and the exclamation point still comes every few minutes. I can't wait to get rid of this phone honestly. And I've had EVERY Samsung phone to date, and this one has given me the most problems by far. I am on my 5th S8+. HURRY NOTE 8!
Running Luma mesh network... Have the same issue on my S8+ after the update...
Definitely due to the update... No issue prior

Thank you! I just changed that setting. I really hope that works!
Other fix is enabling guest network on your router. It worked for me with Netgear Orbi.
I have an orbi and the above fix didn't quite fix my troubles. After enabling guest mode, then what? Use guest mode? Or does just the act of enabling guest mode change something? Thanks in advance.
Wi-Fi Verbose Logging
Yep! This is a problem the carries and Samsung have chosen to ignore so far. I have the exact same issue with two S8's in my household. Everything, all devices, LG, Apple, HTC, Google, Amazon, PC's, etc., including the S8's worked on our mesh wifi network until the two S8's took on the latest update. After that point neither S8 device would consistently work properly on the mesh network. While all other devices, including a Note 5 and Samsung Smart TV, among a plethora of other devices, continued to work flawlessly. It is definitely tied to the latest update on the S8 devices. I reset the wifi, the phones, etc., including factory resets but that did not solve the problem. Verizon sent 2 replacement phones and we have not allowed the latest update to load on the phones and the replacement phones are working perfectly! The latest software version that screws up mesh wifi connectivity is: NRD90M.G950USQU1AQG4. Beware. So far, neither Verizon or Samsung will acknowledge the issue. Only after hours of trouble shooting and persistence on my part about this issue being a well documented situation in on-line forums did they respond by saying they found one case similar to mine but they did not see this as a wide spread issue. Well, for anyone with a mesh wifi network, this is a big issue and irritating as heck! Come on Samsung! Own up to the issue, support your customers, and fix the problem. The evidence that there is a problem at this point is pretty convincing. All one has to do is go on-line and search the issue and bam, there it is. All somebody at Samsung has to do is take an S8 load the latest update and try it on a mesh wifi network. Really try it that is... It work at first but as soon as the mesh network moves the device to a channel or frequency that is less congested, the device will lose connectivity. Sometimes it is sporadic but eventually it becomes a more persistent problem to the point of uselessness. Either put out a patch or push out the wifi portion prior update for us to revert back to. Don't call us liars and ignore the issue. Hard to achieve customer loyalty and retention with behavior like that. I've already had to muddle through the Note 7 fiasco with the 3 recalls and final discontinuing of the device itself. Samsung, don't leave me hanging again.
UPDATE:
Turning on the Wi-Fi verbose logging did not solve my issue. It seemed to work at first. However, after a few minutes it said it was no longer connected to the web when trying to load some very common url's. However, this time there is no "!" next to the Wi-Fi signal on the S8. It now just stops working. Wish I hadn't let it update on the replacement phone. Again working just fine before the NRD90M.G950USQU1AQG4 update.

After enabling guest-network, forget the main SSID and connect to guest-network. If you "allow guest to see each other..." you will be able to see other devices, like printer, Sonos, Roku, etc.
I tried the fix above and did not work for me either. Going back to login in in guest-network.

I need your help everyone. My brother is using the Galaxy S II running ICS 4.0.1 that was bought along with my S III and it is acting up. GSII is running stock ICS, and still in stock configuration. Phone is not rooted or messed with in any manner. The phone connects and stays connected to the Home Network, but data transfer stops after few seconds. All the other devices at home (laptops, PC, other phones) stay connected and works fine. Home network is through Century link and wireless is through actiontec modem and wifi router - http://www.actiontec.com/products/product.php?pid=264#.UOyOPB3aI7s). He has been using this phone with no problems with the same wireless network for almost 4 months and this issue started almost a month ago. I have no idea why it went wrong all of a sudden and not had any luck in finding a solution from all my research.
Problem: When WiFi is activated, it will connect to the home wireless network and will work for few seconds. As soon as background activity that requires data stops, the WiFi stops working. If I am browsing or a video is playing on Youtube, it will stay connected, but as soon as I exit out of the application that is pulling data, it stops working. I have to turn it off and back on again for it to work, but this issue repeats. From looking at the signal bars for WiFi, its full (I was sitting next the router) upload arrow blinks once in a while but noting on the download. None of the apps are connected to the network. Browser will show loading for a while and then displays no network connection message. I tried google play, youtube, third parts apps etc. to ensure its not just the browser. When I turn off the WiFi, the phone seams to download a bunch of messages and updates that was not being pulled for a while. My GSIII connects fine with the network and it works fine even after being idle for hours. I have no idea what is going on and would really appreciate any help. I am close to calling Samsung and T-mobile, but thought I will try here first as we all know how easy it is to deal with those guys.
Things I have tried so far: I have tried all of the following based on suggestions I read from other forums I found through google search.
1. Factory Reset the system: FAIL. After the reset was complete, I waited for everything to finish loading and then I connected to WiFi by inputting all the necessary details. Same results, will work for few seconds and stops.
2. Restart the Modem and Router: FAIL. I do not think it is modem or router related issue as my S III seams to connect and work fine.
3. Turn off the security for wireless network: FAIL. Same result as above.
4. Try different encryption: FAIL. Same result as above.
5. Forget the Network and redo: FAIL. Same result as above.
6. Change the IP address to Static in advanced settings for the network: Worked for a while and then this stopped too.
7. Change WiFi sleep policy: FAIL. Changed it to " When device sleeps", "Never" and "Always", does not make any difference.
8. Third party apps suggested by everyone: FAIL.
This is where I am at right now. I have tried to include all the information possible. Please ask me if any other information is needed.
Last resort ... try a warranty replacement.
Is the phone experiencing the same issues with other wireless networks (coffee shops, McD's)?
[Fixed]
The issue was not with the phone, but with the router/modem. This was the century link modem with wifi and router from walmart that was bought for $99. Its an actiontech router with built in modem for century link. This does not work and dont bother purchasing it. I ended up buying the NETGEAR DGND3300 RangeMax Dual Band Wireless-N Router with Built-in DSL Modem from Amazon (http://www.amazon.com/gp/product/B001UHMB5O/ref=oh_details_o01_s00_i00) for a 30 dollars more, but it works. Only extra step was that i had to call century link for my username and password that needs to be entered during the setup procedure. The actiontech from walmart did this automatically (mainly because this was a century link branded product).
I thought at first my router was having issues, but that is not the case. I have confirmed zero router issues by using 3 laptops and 2 other phones (Samsung units) to connect to anything I want.
If I connect using my M8 (Verizon), it connects with no issue but I have no real internet connection. The signal strength is -40 so that is not the issue.
I have tried multiple restarts, multiple networks, and multiple SSID's. I even tried forcing it to 2.4 or 5 Ghz and nothing at all seems to work.
Is this a known issue? I am coming from a long line of Samsung stuff so I am not up to speed on the quirks with HTC stuff. Your assistance is appreciated!

Stock, custom ROM, etc?
This is a stock ROM with weaksauce root and nothing else.
Ok, so I just connected to the wifi at my office and it appears to be working just fine, but it took about 15 minutes form my phone to recognize that the network even existed.
I am pretty sure this phone is just a piece of crap. About 2 hours after my last post it started doing the same thing (at work). I just got home and did a 100% fresh reset of both my router and my phone to eliminate any possible configuration issues and it shows that it is connected on the phone, but the router is not seeing that it is connected... how the hell does that work?

Since you've determined its a piece of crap, sell it and get yourself a iPhone. Why bother trying to get it to work.
When you connect to your router what details does it give in the phone WiFi settings for that connection?
Also which router do you use?
So I bought a Nexus 5X 2 days ago. When I first started the phone it was running Android 6.0.0 and it didn't have issues. But a update for 6.0.1 showed up and I downloaded it. And then the issues came. It cannot find any wifi network... The problem isn't from my network, because every other device finds my home network and all the neighbors network, but the 5X doesn't find any... I tried factory reset, network reset, cache reset, nothing helped. I even tried Android N beta and for a moment it fixed the issue, but this morning the wifi problem occurred again. I sign out from the N beta and through Mobile network it managed to download the last stable version(that's what google is calling it) - 6.0.1 and the problem was still there.. after some restarts of the phone and some factory resets, i thought the problem was gone, because it managed to find every wifi network in the area, but after i used the phone for 25-30 minutes, the wifi problem occurred again and ever since... So, is this a common issue with the phone, or the android 6.0.1, or is my phone a defected one? Should I go to the store and ask for a replacement? Or will the next phone do the same thing ?

Hi something similar happened to my 5X (6.0.1). It was able to find wifi network but I was not able to use internet even-though internet was working for other devices. I have restarted phone but my phone stuck in to WIFI Obtaining IP address...
I have restarted my router and problem resolved. Happened two times. Might be some bug in software.
I'm currently facing this very same issue, no WIFI networks are showing up. I've already flashed latest N preview with same results, funny thing is that this morning was working just fine. But I had to reboot the phone and now it won't detect any WIFI Network at all.
I'm starting to think I have a failed unit, but since I'm outside the "US" I can't send it back for warranty repair. So I'll just keep it and keep restarting until it's fixed again. This is really frustrating, never happened to me with any device I owned before.

Is it every wifi or just your wifi?
If it is just your wifi, try factory resetting your router after recording the settings, or try removing some entries that my be using NVRAM.
I've seen cases where the router runs out of NVRAM to record the DHCP entries and that causes connection issues. It doesn't show up for other devicdes because their entries are already stored in NVRAM. It is just the incremental new device you add that triggers the problem, so you naturally think the problem is with the new device since all your other devices work with the router.
my solution for wifi not found/working
i´ve upgraded from the nexus 5 to 5x.
i had a really weird issue with my wifi.
only found my wifi when i was not in airplanemode. so i read 1000 of articles about the wifi of the n5x.
just the standard blabla. so i did my own research
while my n5 and my n7 + 2 laptops had never issues my new 5x didnt find my wifi. i really thought it was an hw-issue. but it wasnt.
i am using a fritzbox router. newest update, made a reboot, rebooted phone. nothing happened.
then i checked my wifi channels, set it to manually and instantly found my wifi. i really never expected that the channel got such a big influence. may be the latest update brought a bug for the wifi channels or the hw is just not capable of some channels, dunno. but this is what helped me and it was nowhere mentioned in any forum.
tl;dr
try to change your wifi channel of the router.
edit: btw i found the 5ghz while the 2,4ghz wifi didnt work. but i wanted the 2,4ghz wifi to work because of the short range of my 5ghz wifi.
atm i am on channel 8 and i got no problems with the 2,4ghz wifi network

I don't know about Europe, but usually in the US we only use channels 1,6,11 to prevent overlap.
This is because there is overlap in the channels so you can't really use the in between channels due to too much interference. If you are the only wifi transmission in your area it is fine to use any channel, but if there are others and they are using standard channels for no overlap/interference and you are using in-between channels, your signals are probably going to interfere with each other.
When everyone is using the set channels, then they can negotiate properly and everything works better. With overlapping frequency bands, the negotiation doesn't work well because your signal sometimes looks like noise to the other device.

Hi, thanks for your help but unfortunately it's every wifi... it just hangs on "Searching for Wi-Fi Network..." and stays there...
I already talked with LG and they asked me to send the unit for repair, but I'm no in the US anymore (I was for a short time of period and that's when I bought this phone). So that would not be an option, right now I'm only using 4G and trying to measure it, lol
Just another question, do you guys think I could use a WIFI external dongle through USB OTG? Could that be possible on the Nexus 5X?
Thanks for your help! :good::good:

Hi, thanks for the suggestion but the problem I'm facing it's with every wifi network around, not only mine.
I guess unit is defective, but could a simple reboot trigger this kind of behavior? This is strange, never happened on any device I've owned before. :crying:
In the last 6 months or so I have been experiencing frequent wifi issues, regardless of the custom ROM I'm using. Usually some time after a new installation I am unable to connect to the networks I normally use (my home network and the one at work which uses a proxy server). No matter what I do (clear cache, factory reset, change ROM...) the problem persists. In settings a number of random messages are given: secured, disabled, authentication problem, etc. Every now and then I can get a connection (never at work though) but it doesn't last long. Any help for troubleshooting this would be appreciated. I hope it isn't hardware failure since I'm still enjoyng this tablet after all these years!
Mine started having wifi issues off and on a couple of weeks ago. The wifi started to not turn back on after waking it up, at first just in manually turning it off and then back on seemed to work. Last Friday it just wouldn't stay on at all. I would go to the wifi in settings, it sometimes would get stuck saying turning on. I finally did a factory reset on it, it at first seemed to fix the problem, even spent a couple of hours trying to get everything set back up. Then the problem returned, it just keeps turning the wifi off, if i can even get it to turn on at all. I was going to try and use my phone as a hotspot through Bluetooth (not sure if i can or jot, never tried before), but even the Bluetooth won't stay on. So Sunday, after spending way to many hours fighting with it, i went out and got a new tablet.

Have you tried using the Samsung Kies app to flash the latest stock rom, Dont use Odin or other non Samsung approved flashing software.
I have had my T800 for over 4 years and had no real problem with the wifi connection, But i have heard that there can be compatibility problems with some wifi routers, Also try changing the channel number on your router, Auto channel was giving me poor connection on my PC, I ran the inSSIDer wifi app and it said to manually change my wifi channel to channel 1 the clearest channel as other wifi and bluetooth and wifi dongle even you smart gas/electric can cause interference., auto was picking channel 13 for some reason and it fixed my problem.

Thanks, but since it's the router at my workplace there's not much I can do on that side. Question is, are there any specific steps I can take to verify if it's software-related or if the wifi module is just gone?
Wifi and Bluetooth both use the 2.4ghz frequency, So they can interferer with each other and can cause constant disconnect`s, I have seen this many time, Use 5.0ghz on your T800 if you can, Or disable Bluetooth.
Does your wifi work OK on other brands of router?, Or is it just the one you are using at work.
John.
It's kind of tricky to answer: let's say the times this issue appeared it always stareted at work, but then also at home I couldn't keep a stable connection. Once the problem starts, I get no connection at work at all and very difficult connection at home (meaning it does connect intermittently).
UPDATE. After other attempts and a complete restore of stock firmware, I have both wifi and bluetooth not working, constantly "turning on...." but never activating.
Just curious if anyone else has had any issues with WiFi calling on their S20 variants. I have a stock S20 Ultra on Verizon. I recently noticed my wifi calling would simply just not connect at all. It was also failing on sending some text messages, problems that I surmised might have been a recent wonky app installed. I then factory-refreshed the phone from scratch, and installed from scratch, manually picking and choosing my apps to avoid the same fate. But even so, my WiFI calling is sporadic at best. Incoming calls will ring in mostly, but if I answer the call, I get no sound at all and no one can hear me. Outgoing almost never works, unless I restart the phone, then toggle wifi calling off, wait a minute, turn it back on, and then wait for the icon to display as WiFi Calling able. Then I can get one call out. I can immediately hang up and try again, any number, and it'll just sit there waiting to connect. I have only been able to test it while on my home network. I did also recently upgrade to 50m Fiber internet, though everything is routed through a Google OnHub router for wireless so I can monitor devices in the home. I'm still connecting to the same band that I was prior, and that my other phones (my S105G and S9+) have had no issues connecting and calling from. I do not have a strong enough signal inside the house for calls to connect over the network, so that's out. All other data on the phone works fine from wifi. Texts work more reliably but still suffer from the occasional Sending Error where it times out and I have to resend. Or it'll take an extra 20-30 seconds before it sends. I get the same results if I connect directly to the modem's Instead.
Are there any other suggestions on settings or checks I can look at between phone and network that anyone can think of? This only seemed to happen within the last couple months, too. When the phone was brand new, everything seemed fine.
Edit: Workaround / half solution found, post #6.
Howdy. I just got the S20+ 5G from Verizon. I noticed my mobile data connection going in and out fairly often and texts getting stuck sending. I also noticed wifi calling draining the battery. I've disabled wifi calling for now. I'm a little peeved a $1200 phone has an issue like this.
I know it's been a bunch of months, but I just wanted to follow-up with this. I haven't found a solution but I've all but ruled out the phone as the culprit. As it turns out, all the other phones suffer from the same issues. I even bought a Verizon LTE Network Extender, which has at least solved my text issue - they work reliably now. But voice calling is still a one-way street. Calls can come in, I can hear the other person all day long but nothing can be said back. Since it happens the same way on all the phones, and since it happens even with the network extender, I can only assume the issue lies somewhere either in the modem settings somewhere that I haven't found, or in the ISP backbone itself. Sadly, they're pretty worthless when it comes to tech support (and I should know - I work for them...). I've tried most things I can think of in the modem/router itself, took out my Google OnHub altogether, and still nothing. I've heard ports opened up being a common issue but for some reason, the ports that most people suggest are already showing in use and unable to be set aside. I revisit the issue every few months, but if I ever do find a solution for my case, I'll post back then.

From what you've shared the connection issues would point to your ISP. If you haven't already done so request Verizon do a reset on the fiber connection or switch to DSL if they offer it. At times a COLO, the actual distribution point closest to your home isn't properly maintained or the equipment is in need of upgrades or repair. The only other consideration might be a firmware defect. If your S20 Ultra is operating on Unlocked FW you might want to flash Verizon's latest FW to your device. ATT/Verizon are notorious for compatibility issues with non-native FW.
I actually just came back to add more confusion to my post, but I'll answer above as best as I can:
I don't have Verizon for home service, but Verizon Wireless for my cell. My S20 Ultra was purchased directly through the store, with all Verizon updates installed and current. My home internet is new 50/50 Fiber internet, which was just deployed to the area about 8-9 months ago. I was the first person on the loop to be installed, and it runs fine. I could up the speed if I wanted, but have no need for more. It's new cable from the unit in the field, up to the road, and new drop to the house and new equipment. From that standpoint, everything has been rock solid and works fine. I certainly am not letting them off the hook (or, wasn't until five minutes ago) for what might be a setting somewhere between points.
However, during some more testing, someone mentioned they had an issue with WiFi calling not working. So I did more testing with my S20 Ultra. Turns out, WiFi calling isn't even working at all on my device. I can place it in airplane mode (so it doesn't see my Network Extender), enable wifi, and no matter what I try to do, it will not recognize WiFi for calling purposes. I can enable it fine, it shows enabled, I can restart and toggle all day long. But the moment I try to make a call that way, it tells me I must turn off Airplane mode to make a call. This is in spite of the phone having wifi calling enabled, with WiFi set as the preferred call type in it's settings. This is full wifi from within feet of the router. On a whim though, I took out my SIM card and put it back in my S10 5G sitting in it's box. Calling works perfectly, on both wifi calling, and the network extender. So all that did was confuse me more.
I have an S9+ that doesn't work. I have an iPhone 11 Max that doesn't work. I have an S20 Ultra that doesn't work. But an S10 5G that does. It's the only phone I've found in the house so far that I can make or receive calls from/to, and be heard on the other end. All the other phones, connected to the same wifi and the same network extender all suffer from the same thing. At this point, I've basically hit a wall and am ready to throw in the towel. I was ready to spend another evening messing with the modem until my S10 worked perfectly. It worked on the extender fine. I put it to Airplane mode, enabled wifi calling, and within twenty seconds it registered an outgoing call to my house as a wifi call, completed, and could hear fine. A bunch of coincidences all at once. My fiber internet came with a new modem, though the same model that my regular DSL used prior - when everything worked fine. This new one is configured exactly the same, I kept the wifi configuration exactly the same as before to eliminate having to set a dozen devices back up. So I thought that change still somehow did the phones in, as it was shortly after that I realized that they weren't working right. But then the S10 connected just fine, using the same new modem and everything.
Pretty sure I just live in the bermuda triangle of befuddlement here. I'm just going to abandon trying to figure it out, and go back to just calling back anyone that tries calling, from my home phone instead.
A workaround /semi-solution has presented itself:
The reason my S10 worked was because it was connecting to the 2.4GHz radio instead of the 5GHz one (my router is set up with both configured through what is called "Total Control Wireless" where it configures both under one umbrella with the same SSID, security and password and then lets the devices pull whichever it prefers). But my S10 still had my 2.4 guest wifi in it, and connected to that without me realizing it.
By switching my S20 to Airplane mode, and connecting to my 2.4GHz guest wifi, it works. It does NOT work though, if I don't enable airplane mode. I believe this is due in part to some others I've seen posted where the Samsung phones will automatically attempt to use cellular signal regardless of wifi calling enabled or set as preferred. Noting that the preferred call type is under 'roaming' and likely not subjected to just always using it. So it sees a signal at all, be it from the extender or from even a small signal seeping through the wall, and I guess it tries to use that instead of the wifi. Airplane mode on, 2.4Ghz radio, and I can make and receive calls all day, with no issues with voice.
I still have some more to play with, like disabling the 5GHz band altogether, and so on, but for now at least, I seem to have narrowed it down. Even though this router is set up exactly as before, my guess is something in there isn't liking it. I even set up the 5GHz guest radio, which did nothing either. But for now, I at least have a workaround, even if it means having to remember to disable airplane mode when I leave the house. I think there's rules I can make for that somewhere...
Last follow-up. I don't know if this is really a solution, but for future reference:
I disabled the 5GHz radio in my modem/router. For records, it's an Arris NVG448BQ. I'm not sure what would've changed from the old modem to the new, but I guess it's possible that I didn't have both bands enabled on that one.
However, changing to strictly a 2.4 GHz radio has eliminated the issues altogether with my S20. I will be able to test the other phones later but I suspect the same thing. I don't think it's so much the phones as much as it is something somewhere in the 5 GHz side of the router, despite being unable to find any difference in the way they were set up. I even left it enabled as a separate SSID, and still nothing.
I also was able to disconnect my Network Extender (glad I spent money on that...) and thus eliminate the need to toggle airplane mode on and off. I was worried that the phone would still see a trace amount of cellular signal and prevent things from working, but I made a 30 minute test call on wi-fi calling (which now shows enabled reliably and available, no funky restarting or toggling needed), and repeated testing with sending and receiving text and SMS messages are all working as they should once again.
As far as phone-related though, I'm calling this one solved finally. I do suspect that with a better router and advanced band filtering, I could make things work somehow, but I really don't have any need to do so at this time.
Case closed.
Confirm carrier setting. Or re install carrier setting.
Go to setting / general / about.
Network must be Verizon 4G LTE. Network is good all the time.
HD Voice is activated/
Charlz0_2000 gives 2.4 GHz setting is the best solution here available.
As a follow-up to my last follow-up, and I promise after this one, I'm done. The ultimate cause of all this, was a faulty modem - which I half-suspected at times anyway as there should be no reason an S20 shouldn't be able to use the 5GHz band for Wifi calling. My Modem started completely rebooting at random a week ago, and I finally was able to get a replacement today from my ISP. As soon as I had it installed and configured, I connected to the 5GHz band with my phone and was able to make and receive calls over WiFi with no issues at all. I will keep the bands separate as I do have some smart devices that have a hard time with the "smart" umbrella that the modem defaulted to.
But just for future trouble-shooting for others with WiFi calling issues, it's worth a shot to try one band or the other specifically as a work-around.
Cheers all.
