Currently using Windows 2000. Keep receiving a "No Association with AP" message when trying to connect to the LinkSys Wireless G router. Have tried with Win XP. Same problem. I have tried a static IP address and dns severs. No joy! I swapped pci adapters with a working compter. Same as before. Spent an hour on the telephone with LinkSys tech. support. Running ipconfig/all shows the connection, but no info., ie., no ip address, dns servers, gateway, etc. The person took me through the same steps I got from their web site. The computer is an Intel PIII running at 750MHz. It has 512 MB of ram. Pinging the router does not work. Earlier today I installed a LinkSys wireless B USB adapter to it and the connection was good. I want to upgrade the network to G. Any ideas. Thanks for the help in advance.
