I tried changing the SSID and security as suggested and the new network showed up immediately. Also shut down firewall. WA software is the latest. However, when I tried to connect and put in the security phrase I got the message that no wireless networks were found. . . . . yet the same old "acquiring network address" in shown in the notification area.

Tried connecting a second time and again the network showed up but would not connect at all.

Any help is appreciated. I have been working on this for three days now.
