RUTX50 Problem - looses signal

Hi,

I found this error also here:
RUT241 Wifi disappearing

And maybe here:
RUTXR1 intermittent wifi disconnections

Here is seems that the error was introduced with R_00.07.04.3:
Rut951 wifi disappearing occasionally

Here seems the error start with 7.15.xxx. V7.13 and 7.14.3 should work.
RutX12 wifi disappearing

Another:
Rutx50 occasionally drops 2.4ghz wifi

Here the Wifi signal drops also to 0:
Wifi access point down issue

Exactly my issue is described here:
RUT240 router disabling wifi network

A short search shows about more people having the same issues like me but also on different devices. It seems that this issue is related to the firmware. I think, 1 year ago, this issue didn’t happen but I can’t tell with which firmware version it was introduced.

Regards, Martin
