Wifi calling tmobile - OnePlus 8 Pro Questions & Answers

Callers cannot hear my voice when WiFi calling is enabled on tmobile network. Happens at home, work, and everywhere I connect to wifi. Only solution so far is to turn on airplane mode and then wifi (wifi calling). What's going on here?
Oneplus 8 Pro
Model IN 2025
Android 10.5 (same glitch android 11)

I had this same issue, but only at my regular home, not my vacation home. The only difference was the routers (identical) were configured slightly different.
I dumbed down the router so it was not supporting WiFi 6 and the problem went away. Also, so did all issues about WiFi slowing to a crawl while on the phone. Overall WiFi is now stable and now with bluetooth too.
I am on Android 11 rooted, btw. No explanation on why or how this worked....

Interesting. If this was router related airplane mode would not make a difference imo

Wifi problems?

I'm having wifi issues at home (probably any wifi though, maybe?)
I've got plenty of devices using wifi at home and have never had these problems. Originally it seemed the Note 4 jumped on to "static IP" but I changed it to DHCP. Still though, it seems the connection just drops+reconnects really regularly so I can be using some app that requires wifi (i.e. chrome browsing) and then all of a sudden it'll just cut out for a few to many seconds.
Anyone else having these problems?

My issue seems to be the wifi radio 'hanging' during initialization. When I reboot the phone the wifi works great for a while, but sometimes when I turn it off (out of the house, not near a hotspot, etc), and then come back home and turn it on, it looks like it's starting to initalize, but never does. I have to reboot the phone and then it works again.
Anyone else with that issue?
Same problem here. After a while the WIFI connection will be instable and does reconnects. 5GHz or 2.4GHz freq. makes no difference as well the AP. A reboot of the device will bring back a stable connection for a while.
I think a stupid background process is the problem.

Oreo 8.1b - No WiFi in flight mode?!?

Hi,
In some situations I would like to turn off phone reception, but still use wifi. This always worked with all Android phones and versions. I activate flight mode, and then turn on wifi again.
However, with the latest 8.1b it doesn't. When I activate flight mode, all connections turn off as they should. But when I reactivate wifi, wifi seems to find some networks but does not connect to my home wifi (with great signal strength). When I turn off flight mode, I have to turn off and on wifi again and it will then connect to my WiFi network without problems.
Is this known and is there any workaround?
Thanks,
Eriol
Works fine here. airplane mode plus wifi.

Well, not here ... I tried several settings and also restarted the device several times to see whether this works.
I just want to sort out whether I have a wrong setting and to understand the issue a bit better before posting a bug report to Essential.
Thanks,
Eriol
I found out what the issue is - and just in case this happens to anyone else: I checked the config of my wifi router and figured out that wifi is running on 2.4 GHz on channel 13. (I had explicitly allowed channels 12 and 13 in my Fritz!Box). Now I unchecked channels 12 and 13, and - bingo! Wifi uses another channel, and the PH-1 connects to wifi in flightmode again. Weird thing is that I did not enounter this issue with my Galaxy Note 4, nor with my wife's Nexus 5X.
Hope this helps anyone in the future!

TMobile WiFi calling

How is everyone's WiFi calling? Mine is horrendous even though my wifi signal is good, both 2.4/5g. I have WiFi calling enabled as wifi preferred. Most of the time I look, it doesnt say "TMobile WiFi calling". I am missing calls, can't place calls, sms doesn't send. Aylt least not until it connects to wifi calling properly or randomly gets regular signal. 7t pro McLaren 5g, Sim unlocked, on tmobile, version 10.0.27.HD61B
My 7pro 5g from Sprint has better wifi calling after activating the feature via *#800# and force activating wifi calling and that's not even a TMobile phone.
Any known fixes? Is it the router (shouldn't be since my Sprint 5g works great with WiFi calling in TMobile.)

What kind of router and what ISP do you have? Also consider that, depending on your current location, your ISP could be prioritizing certain connections to accommodate for the HUGE increase in internet traffic.
Xfinity internet. Netgear r6220 router. Internet itself is fine. It does appear that my wifi calling mainly struggles here, at a different place it does work fine from what Ive noticed. Any settings I can change to improve this? Ipsec passthrough is on, went into traffic manager and set highest priority for my phone's Mac address, disabled random Mac address on phone.
on mint ,7t pro McLaren 5g, wifi calling none. first of 6 phones that didn't work. so google voice is it.

finally, i turned wifi calling on/off at the mint site, when i got to strong signal area i rebooted. now it works.

Connection issues/radio instability

Is anyone else having problems staying connected to WiFi and/or cell service with the international version of this phone? After a while, everything seems to die. Putting it in airplane mode and taking it back out seems to fix it.
See the attached screenshots. The wifi will show connected with issues, and the cell service will be zero signal. After toggling airplane mode, everything goes back to normal.
Yours is IN2025 right? Are you on 10.5.4? I had some wifi issues but not sure if it was the phone or ISP problem. I updated to 10.5.5, haven't had a connectivity problem since. The update log specifically points to addressing connectivity problems

Yep, IN2025, but in 10.5.5. What is funny is that it has not happened once all day. It happened so many times the past few days before, that I was able to tell it was usually after putting it down for a period of time (maybe going I to a deeper sleep?). At this point, I'm hoping it will not come back, but I also know nothing changed to have fixed it either.
I wonder if it is related to the wifi calling bug, where not everyone sees it. I noticed the people who aren't getting wifi calling seem to be connected to APs that allow TKIP. I have Deco M9 Plus "mesh" APs, which are generally great, but don't offer much in the way of advanced configuration options... like not being able to select AES over TKIP.
I guess I'm still having issues. Almost immediately after I posted that reply, I noticed my cellular signal was showing really low. It didn't seem to resolve on its own, so I shut wifi off (wifi seemed fine this time). As soon as I shut wifi off, I got LTE+ mobile data, and the signal strength jumped up. I have only recently actually started to trust the signal strength indicator, after the fiasco with Apple marking them up a bit to make it seem like the signal was stronger.
It should be noted this is a partner tower outside my house (which is usually a strong signal) and not the home cell spot. Not sure why I'm not connected to the latter, as I haven't left the house today (which is usually when I pick that up).
Are you by any chance with Charter/Spectrum ISP? My aging netgear router crashed a few times as I was flashing and rooting but I just kept going so couldn't really tell what was going on. I am with Google Fi and have wifi calling enabled but have not had any issues. I do not have the mobile/wifi linking. I did see on 1+ forum that someone had an issue with his router crashing but I believe he had mobile and wifi connection linking enabled.

oneplus 8 pro wifi/bluetooth issues (with a tmobile sim)

So I may have come across something that may help someone else out as well...
Recently (as in less than 15 days) purchased a oneplus 8 pro from oneplus.com. When I first got it it was on android 10 and I was not able to connect to either my 2.4ghz wifi or my 5ghz wifi using WPA2. I had a oneplus 7 pro previously that still connects without issue. I had read elsewhere that the open beta was better so I tried that and it indeed was better but sometimes though I was connected to the wifi, no traffic would travel over the network and it would stall to the point that the only way I could do anything internet or network related was to go to my cellular data. I did the 'device mac' as opposed to random mac and that helped for a brief time however that even cause the same stall/lack of response issues.
Since I don't have much for 5g cellular where I am, I changed it to only look for 4g....still no improvement. On a whim, I disabled any and all security on my 5ghz wifi and low and behold I could connect. I wasn't about to leave either of my wifi networks wide open but also remembered the network I connect at work is also not wpa or any sort of protection so theres a hint as to how to 'fix' these issues. I then read someone about the possibility of having special characters in your wifi password can cause issues. I removed the ! in my old wifi password so it is now alpha numeric and have had no issues with my 5ghz wifi network. I have been able to stay connected with my 5ghz wifi WHILE bluetooth has also been abled and the speeds are roughly normal.
Try at your own risk but in summary:
1. upgrade to the open beta 2
2. disable 5g cellular connections
3. connect to your 5g wifi and make sure the password has no special characters in it as well as use device mac NOT randomized mac
4. perhaps success
With all the above being said, I do still intend on sending this phone back in hopes that I got a dud unit but I'll admit seeing these results makes me feel like its more of a software issue and certain incompatibilities with certain routers.
Just dropping what info I have discovered in hopes it helps someone out there...I would not normally endorse using NO password on wifi or a weak password, but for this phone it may be a requirement at least until the updates can come into play.
Thanks,

I am backing everything up to go to Android 11 tonight, and I switched to a new WPA2/WPA3 router here, but my password has no special characters.
On Android 10, complete nogo, as using WiFi calling with a BT headset on 5ghz slows the network down so much, the other person can't hear you (no upload bandwidth).
I'll let you know how Android 11, OB2 works out for me.
If there are issues, I am going back to the OnePlus 7 Pro and selling the OP8 Pro.
Since I have not been using WiFi, I blew through 55Gb of data this month already so am subject to throttling, thanks OP8 Pro

You could try om a different router of someone else to pin point out if it's your router yes or no.

I did upgrade to OB2 a few days ago and wifi is generally better. But VOWiFi never works with a bluetooth headset - the other person can never hear me.
Also when streaming over WiFi the connection drops or stalls and causes rebuffering. I have confirmed these behaviors with 3 different routers.
Can anyone on TMobile (USA) confirm working VOWiFi while using a bluetooth headset?
Also 4G and 5G speeds slow down when on a call using bluetooth.
Maybe this is all due to qualcomm 865 chipset issues as the galaxy S20 users are having similar issues?
I had faced lots of stability and speed issues on the 5gz band. Received the OS11 update today and my issues seem to be resolved. So far the 5gz connection has been very stable, lightening fast speeds.
