Alright I got my driver installed and running. "iwconfig" shows the wlan0 output even after I restart my computer. Also I typed "ip link set wlan0 up" and "ifconfig wlan0 up" which should tell me that I don't need further firmware because they didn't output anything. So I assumed I was good and I should be able to install Wicd and connect to wireless.
However...
That is not the case. Wicd doesn't see any wireless signals and there should be a lot (I have two in my apartment). I also tried "iwlist wlan0 scan" and all it says is scan complete: with no wireless essids.
Also I tried wpa_supplicant, but I got "dhcpcd wlan0" to just time out.
So is there another step that I happen to forget to do? Maybe it is the wrong driver I installed?
Any help would be great.... Sorry I don't have any command output, I'm at work but I will be heading home for lunch and I can put some up then.
On a slightly different note, I recently purchased an HP Pavilion g4-1117dx notebook which uses the Realtek wireless N card. It is the 8188CE card. After installing Xubuntu 11.04 as a dual boot alongside the original Windows 7, I was experiencing problems with dropped connections, connection speeds fluctuating between 4mbps to 120mbps and poor performance. After several days of troubleshooting, including a visit from the ISP's tech, we discovered a problem with noise on the line, AND poor performance from the wireless card, both in Windows and Xubuntu. A visit to the Realtek site revealed updated drivers for both Windows and the source code for a driver for Linux kernels 2.6.35 and newer as well as a new driver for older kernels. After downloading both the windows driver and code for the newer Linux driver, I installed the driver in windows. performance improved dramatically, but still was less than perfect. The big gain came when I compiled and installed the new Linux driver. Performance is now as consistently steady 150mbps with all the other equipment unchanged ( They're coming out to run a new dedicated line for the cable modem on Monday. It seems the original installer used a splitter on an existing cable tv line rather than running a dedicated line). The only problem I ran into was I actually had to reboot twice after compiling to get the driver working. Since I haven't done much compiling from source it was probably something I did. I still have a small issue getting it to connect automatically but I'm working on it.
