Using the D‑Link DWA-125 with Ubuntu 10.04

Caveat

This meth­od has only been tested under Ubuntu 10.04 (Lucid Lynx), but should work for any pre­vi­ous ver­sion of Ubuntu. Addi­tion­ally, the driver com­pile instruc­tions ref­er­enced should work for any mod­ern Linux dis­tri­bu­tion (2.6+ ker­nel). YMMV.

Overview

The default driver for the D‑Link DWA-125 wire­less 150 USB adapter cur­rently avail­able as part of the Ubuntu Linux dis­tri­bu­tion has errors. This art­icle offers a meth­od for fix­ing this issue.

Requirements

You will need a default Ubuntu install (ideally), a D‑Link DWA-125 wire­less USB adapter and access to an account on the machine in ques­tion that has super­user cap­ab­il­it­ies.

Method

Firstly, plug the device into a USB port and identi­fy it using the fol­low­ing com­mand:

lsusb | grep D-Link

This should return the fol­low­ing text as out­put:

Bus 001 Device 003: ID 07d1:3c0d D-Link System

If the USB device ID is 07d1:3c0d, then con­tin­ue to the next step. If not, then the device is not the D‑Link we are look­ing for and is out of scope.

The issue can be con­firmed by check­ing the sys­tem out­put using one of the fol­low­ing com­mands:

  • grep rt2 /var/log/messages
    which should return some­thing like this:
    rt2800usb 1-6:1.0: firmware: requesting rt2870.bin
    ; or
  • dmesg | grep rt2
    which should return some­thing sim­il­ar to the above out­put.

The next step is to grab the most cur­rent Linux driver from D‑Link, com­pile it and install it. The GNU make pro­gram is needed for this step, but it should already be installed as part of a base Ubuntu install­a­tion. Run the fol­low­ing com­mands to down­load the cur­rent driver source, extract it, com­pile it and finally install it for use:

wget --quiet ftp://www.dlinkla.com/pub/drivers/DWA-125/*LINUX*DWA-125*.tar.gz --directory-prefix=/tmp ;
tar -xzf /tmp/*LINUX*DWA-125*.tar.gz ;
cd /tmp/*RT3070*Linux* ;
make && sudo make install ;
echo "blacklist rt2800usb" | sudo tee --append /etc/modprobe.d/blacklist.conf

If the com­mands above com­plete suc­cess­fully, the new driver has been installed and the incor­rect driver has been pre­ven­ted from auto­mat­ic­ally load­ing. Restart the com­puter and the device will be avail­able for use.

  1. I’ve been try­ing to make my D‑link DWA-125 adapter work in ubuntu 10.04 lucid lynx by a few days by now.
    I find your meth­od to be simple but with the prob­lem that D‑Link does not provide any Ubuntu driver for DWA-125 as is required in your explan­a­tion. They offer drivers for: winxp (32 and 64), win vista (32 and 64) and win7 (32 and 64)

    If you have a link to a DWA-125 linux driver down­load, please share it.
    Thanks

  2. A Linux driver for the DWA-125 is on the D‑Link FTP site, as per the ori­gin­al post above. You will need to com­pile and install the new driver, again as per the instruc­tions, in order for the device to be usable on Ubuntu 10.04, as the cur­rent driver in that release is out of date and unus­able.
