So my Samsung galaxy tab S7 done an update to android 13 last week.
Since then, it has been fine. However, if i connect my bluetooth headphones it kills the wifi speed. As Bluetooth is on 2.4GHz and the wifi connection on the tablet is also 2.4GHz so the interference is causing the issue. I should note that I did not have this issue on older versions of android using same tablet/headphones/wifi router.
My wifi router is dual band (2.4 and 5) so it should switch over to 5GHz if better which it doesn't seem to do. I've looked deep into the settings to see if I can force the tablet to switch to the 5GHz band but can't find anything.
Any android experts on here that can help with this as it's really annoying since it was working perfectly last week?
I'm not an expert but do you have separate SSIDs for the 2.4 and 5Ghz wifi networks? If so, can you prevent the device from connecting to the 2.4Ghz one? ie can you change the password on the 2.4 so it can't connect to it, and fails over to the 5? Or something similar...
As a temporary diagnostic step, can you disable 2.4 on the router and see what happens?
Samsung's Android doesn't seem to show or allow you to pick 2.4GHz or 5GHz, so doing it at the router is your only option. Where are you seeing it's connected to 2.4GHz?
I have the same tablet, same version of Android and no problems using Google, Samsung or Sony headphones. Maybe unpair the headphones and add them again to see if that helps?
I updated to Android 13 on my phone (Samsung Xcover 5) and the Bluetooth connection to the car went flakey. I had to re-pair twice and it seems to be stable again.
Some kind of power saving bug? It's shutting down both BT and wifi when it only wants to shut down BT?
oldnpastit is probably right, see if you can switch off adaptive battery.
And seriously, switch it off and on again. (to flush the BT cache)
For big Android updates, I normally clear the cache. Done from the recovery menu.

Interesting, will give that a try. If that fails I might try a factory reset.

Advanced wifi settings shows you what frequency the wifi is.
