Yesterday I had my WiFi adapter working. I took the Raspi home and installed drivers and manager for my Bluetooth adapter. Now, today, WiFi will not work. lsusb returns the device, but it will not show in WiFi config. Why is this and how do I fix it?
OS: Raspian Wheezy Model: Raspi model B Configuration: OS is on 8GB SD card, Swap on 512MB USB drive as primary with a secondary Swap file. Tenda wireless adapter W311MI. Kensington HUB with Tenda attached.
(I can't ask for clarification yet, so apologies) If it worked before, it should work now, so something has changed. Re-installing the wireless tools package is unlikely to do anything (literally, if it worked before you already have it installed).
Two possibilities: 1. It's a power issue related to powering both dongles. 2. It's a software issue.
There are a few things to try: 1. Plug both adapters into the Pi, see if it works. 2. Plug both adapters into a powered USB hub, see if it works. [My feeling is this second option is more likely to work.] 3. Take the BT adapter out again and see if WiFi works, just to be sure.
Let us know what happens with these alternatives for further diagnosis.
