This router worked nice for about two years.

Well, except for frequent issues with my Lenovo Yoga laptop - it often lost connection until laptop rebooting.
But that issue might be because of bugs in Intel N-7260 Wi-Fi card as well - google for "intel wifi 7260 limited connection"

well, last months the router started occasionally freezing its wifi operation out of the blue. But rebooting it usually helped.

Now this box making new tricks:

day before yesterday it was showing cable connection to my desktop PC going on and off for a while. But after a while that stopped.

today it just stopped providing Wi-Fi at all.
after a while i randomly managed to make it work by setting Wi Fi band to AUTO - and it set it's signal right into the crowd
you can see "LAN3" AP at http://is.gd/O70b7O

anytime i set it to any fixed band - it stops giving wi-fi access right off

turning it to 5GHz makes my phone see it but unable to connect, and laptop does not even sees it

Router's log shows nothing bad... Well, basically there are no logs about wi-fi at all in this router.

i wonder if the power adaptor is dying ? or router? or is firmware got dizzy with years ?

I wonder if i should try OpenWRT or just purchase a new router. Dyign so fast just after 2 years - that is a shame!
