WRT54G Router Channel issue

Hello,




I have WRT54G router, which I tried to connect to my Lenovo U550 Laptap creates problem.

Using 192.168.1.1 Router I changed the channel from 6 to 8. It saved sucessfully. But after that I am not able to connect to router.

Initially I dint have any security setting enabled for my router. But now I could see Encryption as Open and I couldnt connect to the router from my system.

I used reset button for more than 30 s in my router, but still it shows same SSID I was using. I was expecting linksys SSID which is factory setting.
Now I am not using my router. Some one please help me.
