I'm having the hardest time getting wifi working with 0.3 alpha on my new RPi B+. I suppose I could add on to the current 0.3-alpha thread, but I've read through the whole thing a couple times and it seems pretty unwieldy and hard to find info, so hopefully this thread will help others.
I'm using an Edimax 7811Un dongle, although I was trying a TP-Link dongle earlier.
When I have both the ethernet and wifi dongle plugged in, my experience via the UI seems to be:
1) Only Eth0 recognized > Refresh interfaces
2) Both Eth0 and WLAN0 recognized > Input wifi credentials (static IP)
3) No IP Assigned on WLAN0 > select Stored Profile, change security to WPA/WPA2, Connect
4) No network connected (repeat step 3 a few times), shows Connected
5) Check network interfaces, no IP assigned, go around and around in circles
At certain points, sometimes the connection to the Pi will be completely lost (on both Eth0 and Wifi) and I have to hard reboot the Pi.
If I do get the Wifi IP, it will be lost when I turn off the Pi, unplug Eth0, and start it up.
I seem to recall reading somewhere that I can't really manually configure a text file (which I'm a bit lost about) because it won't retain edits. I tried the archlinux guide anyway and got stuck here:
iw dev wlan0 scan
command failed: No such device (-19)
I do appreciate the great work done with this project. I did get the TP-link dongle working for about a day, and it was fantastic while it lasted. Really hoping I can get this working! Thanks for your help.
