Suddenly after Ubuntu freeze I am unable to connect to my router. I have already reset my router but nothing has happend. If i connect my ubuntu with my andriod wlan router it works fine. I have tried lot of things: changed router setting, restarted network- manager, deleted old networks and there is no black list on my router, turned off power management etc. but it still doesn't work with my router. On the other hand i m able to connect with my router from other linux distributions like mint from other computers. Router also works fine with win7 OS.
It's very confusing!!
I have technicolor router from upc. My Wlan0: Ralink Technology RT2501/RT2573.
so again it works fine with other router (andriod mobile) but not with technicolor. But technicolor works fine with Mint,Win7 and Andriod devices but not only with Ubuntu.

"Answer comment-1:Parto" youtube but true :) with alt+print+B (R E I S U B) Good point, i think that would be a problem. Because right after rebooting i was unable to connect to my router. But i have checked couple of config files & compared thier output on forums. But i must have missed somthing.
Booted yes,I have rebooted couple of times. Still there is same problem.
