(solved) Wireless trouble with D-link dwa-125

[jjjrrr3]

I'm trying to get a D-link dwa-125 wireless USB adapter to work.

As directed by the Bluewater manual, I ran fw-detect and followed the instructions to install firmware-ralink and to run modprobe multiple times.  Every time I ran modprobe, I got the same error message:

libkmod: ERROR ../libkmod/libkmod-config.c:684 kmod_config_parse: /etc/modprobe.d/fbdev-blacklist.conf line 6: ignoring bad line starting with 'fb'
FATAL: Module rt2800lib is in use.

Networking is not my strength, and I have no idea what to do next.  Help!

In case it helps, here is the complete fw-detect output:

Detected driver that requires firmware to operate
-------------------------------------------------

#
# Follow these instructions to obtain the correct firmware
# and activate the rt2800lib driver:

apt-get update
apt-get install firmware-ralink
modprobe -r rt2800lib
modprobe rt2800lib

You must first configure apt to install this non-free software,
refer to the offline manual that came with this distribution.

Provide the output of

Code Select Expand

lsmod | grep ralink


That might help someone of the experts here.

That produces no output.

Let's have a look at the file /etc/modprobe.d/fbdev-blacklist.conf -- there seems to some issue with it.

Upon opening the case, it turned out that the laptop has an internal wireless card that had been unplugged.   After fixing that, everything works fine—without needing the wireless adapter.

Thanks, everyone!
