I'm running Ubuntu 14.04 LTS 64-bit and I'm trying to get my Cisco AE2500 USB wireless receiver to pick up the wireless signal. Initially during the install of Ubuntu onto my system I had it connected via ethernet to download all the updates. After rebooting and getting into Ubuntu for the first time, my wireless worked but is getting really bad signal even for sitting right next to the router. If I move the computer back to where it was originally, no signal will reach it.
I've come to find out that it's using my on-board wireless device which I never officially set up because I didn't have the hardware, more specifically, the antenna which it needed. This also explains why I'm getting bad signal even when sitting close to it.
On a previous install, I was able to get my AE2500 to work but I was never able to connect to anything, despite being able to see the networks. On this install, since I actually did the updates this time around, it's using Broadcom drivers for my onboard networking card. When using the NDISWrapper GUI (ndisgtk) I try to use the XP driver set which was valid on my last install but now is saying "Invalid Driver!" with a big red X across it. My guess is that it is thinking this driver is trying to be applied to my on-board network card and not my USB device.
Is there anyway I can choose or make default, this AE2500 device and disable the on-board card so there is no conflict? I tried the "Additional Drivers" and I see the Broadcom driver and I attempt to disable it. When I hit "Apply Changes", it reverts back to what it had. I thought maybe there is a dependency since I was connected via wifi, so I plugged the ethernet cord in, rebooted, and it still won't allow me to remove it.
I'm up for any ideas at this point.
