Turn off wifi. Check operation on Mobile Data only.
Turn on both. Check if phone bounces back and forth between the two. If Data is predominant wifi is weak or malfunctioning.
Confirm with known, strong wifi (2.0 Hotspot)
settings/connections/mobile networks/network mode/LTE...
If you're on Verizon, you can't turn off 5g like this...
btw, I'm on ATT U verse router with same phone... no problems.
Here's another idea... Go to Smart Home Manager on your phone... if you don't have that ATT app on phone get, it... you can prioritize 2 devices on your network. Try doing that on your phones to see if it helps. I think prioritization periods are only 2 hours, but this may lead to an answer if it works. Good luck.
So I had been experiencing a similar issue as everyone else. The WIFI would be connected, I'd be streaming something and then the stream would stop, the WIFI would say it's connected, but then drop it's ability to connect through to the internet. Turning WIFI off/on would bring the connection back, but this was annoying as it could happen many times in a row through the course of a day. My other Android devices and partners iPhone do not experience this. - I should note, that this was only on my home WIFI
I had tried all the of the fixes I could find
- Resetting the Network settings on the device
- Forgetting and re-adding the WIFI
- Resetting the device to factory
- Disabling 5G
- Disabling location accuracy
- Disabling google location accuracy
- Disable WIFI scanning
None of these provided a permanently solution, as the issue would reappear an hour or two later.
What I found worked for me was to disable the Randomized MAC Address option for the specific WIFI connection I was connecting to, I would only do this on your own private home network, and not any public or work connections - as MAC randomization prevents listeners from using MAC addresses to build a history of device activity, thus increasing user privacy. This has been enabled by default since Android 10.0
To do change the setting:
- Open the WIFI Menu
- Tap the Cog on the WIFI connection you want to change
- Expand the Advanced options
- Under "MAC Address Type" change this to "Phone MAC"
- Let the settings apply
- Disable/Enable WIFI and you should be all good
I haven't had my WIFI drop it's connection since.
