Problem with obtaining IP address from router

Hi,
I have 3 laptops in the house. They were all able to connect to the
wireless network. Then, for some unknown reason one of them suddently
failed to do so. This happened after I changed the channel of the wireless
router from 1 to 6. I did this to see if I can improve the reception for
certain parts of the house.

Two of the laptops can still connect without problem but not the 3rd one. I
would get the error: Limited Connectivity. No IP address has been assigned
to the 3rd laptop when I checked using IPCONFIG.

I tried rebooting the laptop, disable/enable the adapter, etc. But, none of
them worked.

I do not understand why. Pls help.

Thanks,
William

Yes, the router was reset, along with all the devices.

I would reset the router first.
