Problems with WiFi network.

Check your RAM usage.  I had this or a very similar router,  worked for a while,  then suddenly only RAM issues... 

 

How much RAM does this router have anyway?

I wouldn't assume overheating wasn't the problem, as if its been running hot enough for a while the capacitors could have cooked causing power instability which would explain why it fails once you start doing actual data transfer.

I assume you've power cycled it to see if it happens again straight away or takes a while?  If it takes a while then starts again, it could be a firmware bug causing it to run out of RAM where is why it would seemingly fix itself briefly before failing again, as it may never be able to free up enough RAM to fully recover without a reboot.

256 on 68u, I think first thing I looked was status and all was good. Right now my new cheap router uses almost all RAM and works just fine...

More or less what I saw, it was not even 50% RAM and CPU usage.

New router is also pretty hot, so I guess its was not overheating. In any case hot = normal for something with entirely passive cooling. + Its not like 100C hot

As for firmware as I said when problem started one of the first things I did is updated it, so its either 2 bad firmwares, or not firmware at all.

It happens as soon as I start to actively use wifi, basically few(3-5) minutes after. Too bad Asus routers logs are pretty much useless, at least it this case, I expected to see some error message. btw if it was RAM problem I think logs suppose to show it but who knows.
