usb 1-1.2.6: SerialNumber: ********************
The driver is included in the kernel, so I did modprobe rt2800usb per this. There is no wlan interface in ifconfig. iwconfig displays the following:
- Code: Select all
ifb0 no wireless extensions.
lo no wireless extensions.
eth0 no wireless extensions.
ifb1 no wireless extensions.
I tried plugging/un-plugging the dongle as well as rmmod/modprobe again and again without any change. Then the helpful people at #archlinux-arm on Freenode IRC pointed out that I should actually be using the 8192cu driver. Same results there.
Here's my physical setup:
Lapdock micro USB -> Pi USB 1
Lapdock micro HDMI -> Pi HDMI
WiFi dongle -> Pi USB 2
... and that's it. I don't have a powered hub. I also tried this config:
Lapdock micro USB -> Pi USB 1
Lapdock micro HDMI -> Pi HDMI
WiFi dongle -> Lapdock USB 1
with the same exact results. Finally I tried this:
Lapdock micro USB -> Pi USB 1
Lapdock micro HDMI -> Pi HDMI
WiFi dongle -> Lapdock USB 1
Power supply -> Lapdock USB 2
thinking that the Lapdock acted as a powered USB hub of sorts (I forget where I read that). No change there.
Do I really just need a hub? Or should I get a different adapter? I'm looking at a ASUS USB-N10 or a TP-LINK TL-WN821N. I just hate to buy anything else after I FINALLY got my adapters in the mail.
