[GTALUG] Raspberry PI wifi problem

[Evan Leibovitch]

Hi all.

Making networking run on Linux desktops has always been IMO one of the
reasons why it's not caught on. Stuff just shouldn't be this hard.

I have a RPi Model B running current Raspian, and a wifi dongle that claims
to run on it.

`lsusb` reports it as
Bus 001 Device 004: ID 148f:7601 Ralink Technology, Corp. MT7601U Wireless
Adapter

and `usb-devices` says:
T:  Bus=01 Lev=02 Prnt=02 Port=01 Cnt=02 Dev#=  4 Spd=480 MxCh= 0
D:  Ver= 2.01 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
P:  Vendor=148f ProdID=7601 Rev=00.00
S:  Manufacturer=MediaTek
S:  Product=802.11 n WLAN
S:  SerialNumber=1.0
C:  #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=160mA
I:  If#= 0 Alt= 0 #EPs= 8 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)

Now... even though it says "Driver=(none)" on that last line, `lsmod`
reports:

So there is a module called mt7201u being loaded yet it's not seen as the
associated driver to this card in usb-devices and it's definitely not
showing in ifconfig or iwconfig.

Any suggestions on what I'm missing is greatly appreciated.
