AC5300 upgrade to 386.2_2 2.4Ghz radio not working

Hey all,

yesterday I upgraded (nuclear reset and M&M config) my AC5300 to 386.2_2, but since the upgrade the 2.4Ghz radio works for some time and then just stops working.
This means, first I have an extremely high ping to 8.8.8.8. When I switch to the 5Ghz radio (which works fine), I cannot even reconnect to the 2,4Ghz.

The temps are:
Legend: 2.4 GHz - 5 GHz - CPU
Current Temperatures: 50 °C - 55 °C - 71 °C

There are no USB devices connected and I didn't load any backups (JFFS, configs, etc.) after the flash.

Any help is appreciated, since most of my devices at home only support 2,4Ghz :(

Thanks!

The log of the router is also spammed...


Btw, please let me know, if I can provide any more information that could help!

I am having the same problems with GT-AC5300 (f/w 3.0.0.4.386_42643-g16dc577) - the devices in 2.4GHz can't access internet after a few days - have to reboot the router. Have not changed ANYTHING recently - the problem started just like that. Have done a reset and running pretty much default options. Any pointers? The 5GHz has no issues at all.

Hi all
on a RT-AC88U I have the same (or a very similar) problem.

There's one think I noticed, though. Three days ago I manually chose a control channel instead of using "Auto", and, so far, it's stable.

For me this also started happening when I upgraded to 386.3_2
