Try a hard reset.
There a small hole somewhere on the router.
Press it with a pen, etc. for 30 seconds (with power on).
Then log in to the router (192.168.0.1) and check/adjust your settings as desired.

Yes. The router turned out to be the problem. I tried resetting it few times. But it was glitching after some time anyway. So what solved my problem was firmware upgrade. If it helps someone else: the router is Asus RT-G32.C1 and the firmware can be found at asus support site –  uKolka Apr 28 '12 at 5:41
