Wi-Fi Connection Anomaly
This is not a request for help. I report this as an anomaly and believe that this is about my computer, not something other users may have a problem with.
I use a D-Link WDA-160 wireless adapter to connect (via AT&T 2Wire modem-router-wifi).
The 2Wire device has a secondary Apple AirPort device connected as well. In the panel icon for signal strength, I see both devices as well as others in this area.
Of late, my Precise Pangolin (v. 12.04)using XFCE will not connect to the 2Wire router, only the AirPort. I switched over to Gnome (no effects) as a double-check, but no dice. When the Network Connections (manager) tried to connect to the 2Wire, it says something like: requesting a wireless network address for '2Wire999'... . That address never connects. But in true Linux style, the secondary wifi (Apple AirPort) is found and a connection is reached. I have backup 'net access.
When I first purchased the D-Link WDA-160 I was so please that it "just worked". It's a USB device and has given excellent service for the past 9 months. Whether this is a hardware problem or not is beyond my tech skills.
If anybody reading this has the faintest clue about this problem, I would be obliged for the information, but I'm not expecting to "fix" this. I'm considering buying another wireless adapter access device.
