Not getting text messages when on wifi in basement

My office is in the basement and and I only get about 2-3 bars of cell signal. I'm always connected to wifi but when people text me I do not get it until I turn off wifi. It only does that in this location. Anyone have a solution for this?

Is it a home office? It could be a firewall issue

No it not a home office. Its open wifi at a University. I dont think its a firewall issue because when I got up to the third floor in still connected to the same wifi and I am able to send and receive text.

It still could be, if you went 4 floors up a building, you undoubtedly changed access points, different floors usually means different switches as well, and the switch could also be connected to a different router, or VLAN in the switches. Different VLAN's can and often do have different access... based on access control lists or ACL'S. ..

You are correct but I know that all our APs are on the same switch and vlans. I should have said tyhis in my orginal post that it does work sometimes. Its usally when my cell bars drops below 3 bars that it doesnt work..

Okay, then it could be that it's intermittent on the cell connection, and the phone tries to run most of the connections through the wireless, and it's missing the connection on the cell side, and since it's intermittent, and it has a connection via wireless, it's not trying as hard to make the cell connection, and can't get the push notifications on the LAN side. When it gets enough of a cell connection, the sms push notifications make it on the cell connection, if you force the cell connection, it tries harder to make the connection work, it normally wouldn't to save battery use.

I went into wifi calling setting and choose use cellular first. Is that what you're referring to?

No, that's not going to do anything about the push notifications from the carrier for sms messages, that's for routing voice calls. You may want to contact your carrier, and explain the situation, and ask if the sms push notifications go only on the cell network, or if they go across the Internet, if they go across the Internet, talk to the universities IT help desk and ask if they block sms push notifications. As far as making your phone deal with the cell network differently, that would be a question more for a developer. ..

never mind, wrong forum

Try changing your APN settings.
APN Protocol: IPv4/IPv6
APN Roaming Protocol: IPv4/IPv6

This is how I fixed my phone from not sending/receiving text while connected to my Wifi at home. Copy down all of the stock APN settings and then create a new one and change the APN Protocol and APN Roaming Protocol to IPv4/IPv6.
I try to spread this information as much as possible because of how frustrating it was not getting Text. Also you have to turn off Wifi Calling or switch it to "Cellular Preferred.
Hopefully this fixes your particular problem. It did for me, after switching to T-Mobile.
Good luck!

note 4 wifi issue

ok so i searched everywhere for this and couldn't find a solution. i have a note 4 and it will connect to my home wifi just fine. i can search the internet on it, but facebook doesn't load and neither do certain games and the app market loads very very slowly. when i had my S4, it would do everything just fine. i was at my friends house and connected to his wifi and everything loaded lightning fast. so i know it's a problem with my wifi, i just don't know what.
my modem is netgear and my router is belkin AC 1200
any ideas on what to check so i can fix it? i suck up a lot of data lol

Do a speed test on your wifi with another device to determine if it is your phone or your wifi. How does your phone perform on 4g? Does it do the same thing?

the wifi is fine. i can browse the internet, watch netflix, etc. When i'm on my data, everything loads like it normally would.

bump for some help

Try hard resetting you router and before customizing it(changing SSID, encryption, etc...), test it with your phone to see if its any better.

it didn't seem to help. it's dual band and i tried on both. it wouldn't even load the google play until i switched bands.

any other ideas of a possible fix?

Yes.
I just got my VZW Note 4 yesterday and noticed almost the exact same problem. There is a little bit of info out there talking about things like power saving mode and stuff, but I noticed that my speedtest.net throughput was excellent. My next thoughts were DNS resolution or an IPv6 problem. Turns out my wireless router had a default setting with IPv6 routing enabled, but my ISP does not serve IPv6. You may notice the same kind of initial lag on Ubuntu installs (especially with certain VPS providers) where every single command you issue seems to take ages to start, but then completes quickly. I know how to deal with Ubuntu to force a preference for IPv4, but a locked down Samsung phone is a different matter entirely. Thankfully, I was able to just turn it off in the router.
For my specific router (Belkin AC1200 DB), the user interface has an IPv6 settings page, but the options they present to end users isn't intuitive. I changed my 'connection type' on this page to "Local Pass-Through Only", and my problem immediately went away. Have a look and see if you find anything similar.
Thanks, and good luck!

DUDE!! this is exactly what i was looking for. i think this fixed my issue. surfed facebook briefly and it loaded everything instantly. i'll check more as the day goes on. thanks so much man

Fixed My Issue too!
Hey Guys
Newbie here! I just wanted to say that this fixed my problem as well. I don't usually post as you can tell by my info but this was worth coming out of the dark to reply to.
Now to clarify, I too have a Belkin router AC1200 so it may be specific to those. Anyway thanks for the help and enjoy the fish!

someone sticky this! i have the same wifi issue , i am at work right now but i will try it when i get home! , i hope this works!

I am having this same issue bUT Comcast here uses ipv6 as well,I have a Belkin n1 router what do I do?
---------- Post added at 07:39 PM ---------- Previous post was at 06:50 PM ----------
never mind i disable ipv6 in my comcast modem and it seen to do the trick, any idea why this is happening?

I've been having the exact same issue on my Note 4. for the past week or so. Our router/modem is a DPC3941T from Comcast, and I can't seem to find how to turn off IPv6. This setting was under Connections > Local IP Network. If anyone could help instruct me further, you would be a great help. I'm pushing my data cap for the month as it is because of this >.<

I'm having the same problem too. The funny thing is that I went to the Verizon store to see if they could trouble shoot it and the phone did not work on their wifi network either! I realize now how to access my IPv6 settings in my router and that does seem to fix the issue. Unfortunately I cant imagine very many businesses with wifi networks will allow me to reconfigure their router everytime I want to use wifi.....

I started having this issue when I upgraded to lollipop. My Netgear C6300 AC1750 doesn't seem to have an option to disable ipv6 though. Any suggestions?

Force 5ghz WiFi.

As the title may suggest - is there a way to force 5ghz WiFi. There used to be an option to choose WiFi frequency band but I can no longer find this.
Thanks in advance for any help.

Can't be done anymore unless the ssid is different for 5ghz frequency. If the ssid is the same for 2.4ghz and 5ghz, the phone will automatically pick the strongest signal.
Maybe there's an app or something that allows you to force it.

Ah...explains why I can't find it :/
Thanks for the quick reply!

I have separate SSID's (names) for 2.4/5Ghz. I just "forget" the 2.4 Ghz AP and so it is not available. Not related but there is a setting in Hotspot setup where you can select which band you want to use. Maybe that's where you saw it?

No, you definitely used to be able to select the frequency band in advanced settings.

Keep in mind i don't have a Pixel 2 XL yet, this was from a different phone but it might apply.
Wifi > 3 dot menu > Advanced > Wifi frequency band > 5Ghz Only.
I'm not sure if that helps, but i thought i'd try.

I see what you mean. When I say you used to be able to I mean on older versions of android on older Google phones. It seems to be a setting that has been phased out for some reason.

My modem has two different passwords, one for 2.4 and one for 5g

wifi band

hello
Is anybody know how to change the wifi band??
Of 5Ghz to 2.4 Ghz
let me know please

LOL. Both are active at the same time. You just select 5 or 2,4Ghz access point

I dont need for acces point, I need to change it on a50 to pair with gopro app

It is not true if both bands share the same SSID... It is common at enterprises for example

I do not know what you mean. In: corporate networks or hotels it is more complicated as wifi APs may be centrally managed with roaming like: Mikrotik CAPsman.
But this if far beyond the scope of this topic.

I still do not get what is your problem. A50 scans both 2,4 and 5 GHz bands simultaneously for APs. You should see your GoPro generated SSID with no problem

I think I'm writing simple plain easy to interpretate English.
Wifi routers of some corporations spread their 5 Ghz and 2,4Ghz bands over the same SSID, and current Android versions don't let you pick the band in this cases. If you have a problem connecting to a 5Ghz band and you prefer the 2,4Ghz band instead, you have no means to do this since Android Lollipop.
I think this is the scope of the topic.

Wi-Fi drops for a split of a second

I have the 7T for about a week now and it's really a fantastic smart phone.
The only problem for me now is that the Wi-Fi seems to drop for a split of a second (which disconnect me from online games, such as COC) then it's OK again, the Wi-Fi icon on the status bar disappear for a second and then appear again.
The problem is really annoying and could happen for several times for a few minutes and has this happening both in my home and in my work, I guess this is not a router issue.
I turned off the battery optimizations features (adaptive battery and sleep standby optimization) and also some Wi-Fi features (such as intelligently select the best Wi-Fi and auto switch to mobile data)
My phone is updated with the latest Oxygen OS 10.0.6
Any idea?

No,
But I have the exact same issue, I’m hoping it’s a ROM issue that will be fixed as no other devices in my network have problems.

I have noticed this only when connected to 5 ghz channel. I'm using a TP link router with ACT broadband and wherever I have faced this issue apparently all the places have the same router.
My thread on the community : link
The screen recording of when it happens.

I have ubiquiti AP'S with 2.4 and 5ghz (connecting at 5ghz) and which are rock solid normally and certainly with all my other gear.
I'll take a look at your thread. Thanks.

Same issue for me too. Just got the 7t a couple days ago

Damn, I just ordered a 7T and I'm hoping it works well. I had a 6T, using here on T-Mobile in the States, and it would drop the LTE connection quite often. It would reconnect automatically in a second or two, but it was super annoying and I ended up sending it back. I know this thread is about Wi-Fi but it brought back memories. I'm hoping these phones don't have issues with the modem or something.

Dont wanna sound selfish, but im glad im not the only one with this problem. Still dont know what is the issue

More info
Seems that the problem occurred only when I'm not close to the router (although the signal seems to be OK) and the Wi-Fi switch from the 5 to the 2.4 ghz and then from 2.4 to 5 ghz continuously.
My home router uses the same SSID for the 5 and 2.4 ghz network, I tried to disable the 5 ghz just for testing, but I could not do this as my router is managed by my ISP.

After system update to 10.3.0.HD65AA problem seems to be solved, although WiFi is not mentioned in the update log.

Same issues with a Ubiquity mesh system. Thought it was the handoff between APs, but maybe not. I'm on stock 10.0.5 TMO. It's done it since I've owned it which was launch day. I don't game or anything so it's just been a slight annoyance. I can confirm this is the only device having the issue. My wife has a V30 which is fine and my two daughters have Samsung Galaxy 9s which are also fine.

Hello my english is not good, i can only reply using google translation,
hope you could understand
I have the same problem as you, and I have updated 10.0.8, but the problem persists, but I found that only a few people have this problem, so I try to change the settings of my asus gt5300 router. turn off Smart Connect function and separate the SSID of each 2.4Gzh 5Gzh, because my router is with 2 5Gzh so I also separate it into 2 SSID
If your router only has 2.4G and 5G, just separate them.
I tested it for a few days and it worked out 5Gzh Wi-Fi drops for a split of a second
