[Q] Wireless Issues with Note 4

Has anyone experienced issues with Wireless?
I will be connected to a wireless network, can disconnect and reconnect just fine, everything seems to be working, but if I open an app that is trying to load data, it does nothing, as thought I have no connection. I have tried turning it off and on, forgetting the network(s) and reconnecting and the only thing that ever fixes the issue is a restart of the phone. Once I restart it will work just fine until the next "blip" in the radio.
Thanks in advance,
Zach

Yep, I have this issue but only when connected to my WiFi extender. Connecting to the main router works fine.

Just to add info, I connect to a Samsung Verizon Extender every day since owning the Note 4 and have no issues.
I also have never had any issues like the OP mentioned. I would start looking at apps you have installed.
Remove and test and so on. I did a quick search and did not find this to be any known issue.

My issue exist on both me and my wife's note 4. Both exhibited this issue from the initial setup. It's unfortunate and annoying. If it weren't for the camera and s-pen I would've already gone back to my M8.

I found this, maybe it will work, sorry you are having troubles.
Problem: Wi-Fi connection
Every time a new smartphone is released there are a lot of reports about problems with connecting to Wi-Fi networks or maintaining good Wi-Fi speeds. Here’s what to try if it happens to you:
Potential solutions:
Try turning your Note 4 and your router off for a couple of minutes. Now turn them on again and retry the connection.
Take a look in Settings > Power saving and make sure that low battery life isn’t restricting your Wi-Fi.
Try forgetting the connection, choose your router in Settings > Wi-Fi and Forget. Enter the details again.
Try the free Wi-Fi Analyzer app and see if the channel you’re using is crowded. Change to another channel if it is.
Take a look at the settings on your router. Make sure that MAC filtering isn’t on, or add your Note 4’s MAC address, which you’ll find in Wi-Fi > Settings > Advanced.
Make sure that your router firmware is fully up to date.

None of these work. Restarting the phone always works.

Thanks. Funny you should post this, I read it right after I posted here and was planning to check out the MAC filtering when I get home. Weird thing is this: My phone connects to the main router fine, with zero issues of any kind. We have a WiFi-extender by NetGear. My phone will connect to it, but will not exchange any data. My computers, HTC One, and my wife's old S5 all connected to the extender fine. Now, neither of our N4's will properly connect to it. It certainly doesn't seem like an issue with the extender, but that's not to say it isn't possible, and I sure hope that it is and not an inherent problem with the phone. Will try some troubleshooting tonight and report back.

I've run into an issue with the wifi since getting my Note 4 last Friday. The problem I am having is it will connect to my wifi network without any issues, but after a while (it could be 2~8 hours) my note4 will lose it's connection to the wifi router and not be able re-connect until I reboot the phone. I have a dual band ASUS router with the latest firmware, when the note4 craps on itself with the wifi, the wirelessG connection will keep asking for the password and come up with "authentication error" and the wirelessN connection will come up with "unable to obtain ip address"
When the note 4 has this issue, my router log shows "Dec 9 16:54:28 kernel: eth1: received packet with own address as source address", checking further into the logs on the router, this didn't start popping up until I got the note 4. I am hoping it is a software issue, Verizon did however confirm that there is an update coming out the the next few days to address a wifi performance issue...
I have other wireless devices that use both wireless G & N and don't have any issues, i've rebooted the router a few times even though that is not the problem. I even hooked up a different router to see if that would help, but the same problem is still there.
After playing around with different settings, I have yet to find a solution to this problem. Verizon support has me running the phone in safe mode to see if it's an app causing the problem.....

Are you by any chance using 5 GHz on your router? I am having issues with 5 GHz connections and no issues with 2.5.

Try the DNSet application - I had painful Comcast WiFi speeds, or lack thereof, and running this application before turning on WiFi solves the issue. Not sure if it's just me, but you should know that MMS doesn't work when the DNSet application is running.

What is stopping us from hardcoding DNS entries in the WLAN config now that we have root? Is this possible?

I looked at it, but the app needs to create a VPN to work, which is a whole other can of worms.

Do you have Comcast? I've learned that Comcast rolled out IPv6 out of nowhere, and many of its routers have issues with some phones (my gf's iphone included). I rooted my phone, disabled IPv6, and now I'm back to consistent 50-80Mbps download speeds on my phone.
Before, I would open up the Speedtest.net app, it would take a full minute or more to locate a server, and then the needle for the download speeds would constantly bounce between 0 and 50, sometimes with my phone prompting me that I lost my internet connection, asking if I would like to switch to data. Worth a shot! If you can't root, DNSet does this for you through the VPN, or you might be able to find a way to shut it off on your router.
I don't seem to have any issues with my phone picking up IPv6 over data or a few other routers, though, so I think this issue is more due to some bad firmware on certain modems.

Yes i do have comcast, their is many other cellphones in my house galaxy s5 ,s6, lg g3, iphone 6, none of them have problems but mine, how do i disable IPv6 once i have root

From the G3 after the 5.0 update, the fix was to disable IPv6 as well. This isn't related to IPv6 though, as it only seems to effect the G3/G4. Also, Google "What is my IP" when on mobile data and you will likely have an IPv6 address from Verizon.

I don't know that it isn't related to ipv6; Samsung phones have similar issues and my girlfriend's iphone does as well. I don't think the problem is the protocol itself, but how certain modems (seemingly Comcast ones) incorrectly implement them in their firmware

Ipv6 wifi issues

I recently moved and got new internet service and ever since I've been having issues with the Wi-Fi on my phone. I have 300 mpbs internet service and so I expect my phone to scream through updates in seconds... But ever since the move apps like play store and google drive are slow as hell. So after trying everything I could find online I figure I'll ask for help.
I've narrowed the problem to IPv6 issues. At my old place I had Ipv6 working so I never had any issues. But now when I go to test my Ipv6 It's not working. I'm renting a modem/router from my isp. I know buying my equipment would probably be the easiest fix but that's not an option right now.
There is an option in the router configuration to disable dhcpv6 but that's not solving the issue. The test says I have an Ipv6 address but the dns does not resolve. I found an app on playstore called Ipv6 tool that disables it and my phones works after doing that but I'd love to figure out how to just get my Ipv6 to work. I'm going to exchange the router today to see if it's just the equipment. If anyone knows how to remedy my issue I'm all ears. If anyone is having issues like mine Ipv6 tool is a great temporary fix.
EDIT- SOLVED---- It was a network issue. In my router configuration I had to disable dhcpv6 and then after that renew WAN lease.

I noticed WiFi issues the other day and then noticed my sky box had updated and had lots of ipv6 settings. So I assumed it was to do with that.
I think it can be disabled but haven't looked into yet. But my device sometimes flies through some tasks but then grinds to a halt on others.
Glad I'm not the only one

The Ipv6 tool pro works pretty good after you do some configuring. But I'm leaning towards its a network configuration issue not necessarily an issue with our phones..
You can just disable Ipv6 by entering “echo 1 > /proc/sys/net/ipv6/conf/wlan0/disable_ipv6" according to these guys. But I saw the app before I learned of the command.
I'm back to updating 30+ apps in less than 10 minutes. I was getting mad because it was taking about two hours to do this. And being a flashaholic that seriously cuts into my flashing..lol

WiFi not working on Pixel 2 XL

Any of you guys having the same issue? Mine started acting up earlier today, LTE works completely fine but can't seem to get WiFi to work at home. WiFi connects just fine, does not show there's no internet or anything. Works for the first 15 seconds I toggle on and off but then nothing afterwards. I have tinkered around with my router settings, including switching to IPv4 as well as activating the option to randomize MAC address on my phone under developer options but to no avail.
Please advise, thanks in advance!

If you are doing that much tinkering then I bet you have done way more tinkering than you have explained.
More than its worth actually unwinding.
If your phone works on all other wifi but yours it is probably your router
If your router works for all devices but your phone your router is fine.
Factory reset your phone.
Dont install try to use it fresh from install if it works then your fine.
Just watch what you tinker with.
If it works it is something you did after the fact.

I've had exactly the same thing start happening to me today. No problems with data over wifi before today, and I haven't made any changes on the router.
All other devices seem to be unaffected when connected to that router, and the phone has the issue whether it's connected to that router or a separate access point (connected back to the same router, so it doesn't completely rule out a router problem.
Edit: It seems that when the problem starts it's only internet traffic that's not getting through - I can still access servers on the local network.

That sounds like a DNS problem, are you using anything that changes dns servers?

It does seem to suggest a DNS problem. I just have Pie's "Private DNS" setting set to Automatic, but I would assume that applies to LTE networks as well as wifi, whereas LTE data is unaffected for me.
As a test, I've set Private DNS to Off now, and I'll see if that solves it.

"Android then sends all DNS queries over a secure channel to this server or marks the network as "No internet access" if it can't reach the server" sounds a bit like what you're experiencing

That's interesting. Setting Private DNS to Off has so far fixed the problem for me. I'm guessing that my mobile network's DNS servers don't support DNS over TLS, which is why LTE wasn't affected with it set to Automatic, and my wifi's DNS provider does support it but is currently broken.

I believe that's the case, I turned off Private DNS and it seems to be working fine now.
Thanks a lot guys! Very interesting.

I'm here with this issue now, I'll turn off private DNS and give it a try, this is driving me mad. thanks everyone!
Edit: been using the device for 30 minutes now with no problems, thanks for the solution!

I'm using a local DNS server (Pi-hole) to block ads and I had to turn off Private DNS, otherwise my phone was also reporting that it had no Internet access.
Private DNS seems to cause issues to many people

Never mind i'm foolish.

Holy crap, thank you guys. This just started happening to me and my wife a few days ago and thought my router was going bad since it was multiple devices. Then I noticed today that my laptop and a few other wireless devices were having absolutely no problems.

On mine it's being caused by the Snapchat update from a few days ago. Avoid Snapchat and WiFi is flawless again, as soon as I open it the WiFi stops working and I have to turn WiFi on and off before it springs to life again. Exactly the same on my eldest's 2xl and youngest's P10 lite.

WiFi Issue

S20 Unlocked from Samsung.com
Carrier: AT&T
Issue:
When on home WiFi network, the S20 does not load images in apps such as Facebook, Instagram, etc. Slows to a complete crawl.
If I test on fast.com, I receive normal home speeds on mobile of 200-400mbps
If I turn off WiFi, performance immediately returns to as expected.
Any ideas?
Router is Netgear XR500
Quality of Service is off.

Did you try a reset of network settings under settings?

Just tried that.
Fast.com reported download speed of 500mbps
I was able to download an app at an appropriate speed
It seems to be only Facebook and Instagram that are still showing the issue -- extremely slow load times.
Both work as expected on LTE.

Android System Web Viewer did take forever to update while we set the phone up. I'll see if I can roll that back.
I don't have any issues with any of my other android devices on my router - but I'll also check IPV6 settings.

No luck trying this.
Tried turning IPV6 on - in router settings. No difference. Turned it back off.
System web Viewer had an update. Updated. No difference. Disabled it. No difference.
Those two apps still wildly underperforming on wifi.

Try it on a different wifi connection outside of home? Same results?

I tried it on another phone's hot spot and could not replicate the issue.
I guess that means it's a problem with the router settings. Not sure how.

I have the same phone, carrier and use wifi at home as well. No issues, sorry you're having problems....
Maybe a full wipe?

Hope you sort it out sir, I normally don't get unlocked on ATT due to losing WiFi calling but I get a better signal now and you can just call to get visual voicemail fixed if yours doesn't work right away so I'm loving it....
I'm sure you'll love it too once you get it sorted...

Bringing back zombie thread.
Was a fix found?
My 20+ is having problems with wifi slowing to a crawl after just a few minutes.
Just bought a new router TP-Link AX11000 and it started so I thought it was the router but everything else on wifi in the house gets expected speeds my two 20+'s not so. I think it has to do with WIFI 6. If I stay within 10ft of the router everything is fine after that... I go in my bedroom 30ft away and have -63dbm signal strength and I can run a speed test and get 500mbps down try again and it will start at 500 and slow to around 45 try a 3rd time and and I barely get 4mbps 4th time and it's 0 with signal strength still at -63 on all of the test in the bedroom my upload will be 45mbps.

after a lot of testing with battery settings and things on the phone found out that my slow wifi was due to 2 settings on the router.
first in your router disable WMM, this made my s20+ use like 30mbps max in my case. now list my wifi 5ghz as +800mbps
seconds, disable ipv6 on the router. this made my phone ultra slow to everything. like play store hang on app updates, google drive take forever to load every single photo, like is taking forever to get the first reply from the server.
with that changed now the phone works at full speed on wifi. play store updates are shocking fast.
so lame that a flagship that cost nearly 1 thousand dollars have to disable things externally to work properly. no other phone or device works bad with the previous config of WMM or IPv6. I have a Linksys WRT1900ACS.
Hope they fix it with a software upgrade.
