I was connected to Uverse, but I got a new computer, and setup my wireless reciever. It can detect my 2wire network, and it shows a strong signal, but when I type in the wireless encryption key, it wont connect.
I used to see the Limited/No Connectivity message a lot and it was because of interference, somewhere, with something/someone. Nothing to do with my Key being incorrect.
1) Try changing to another Wireless Channel in the RG.
2) Download (free) Net Stumbler and see which channels are being used in your 'hood; pick one that isn't being used by many.
3) DUMB QUESTION, but maybe you are looking at ANOTHER 2Wire in your neighborhood and it isn't yours? If still the 2Wire (with 3-digit #), would recommend changing it to something YOU recognize/remember.
