Wireless network adapter on CentOS 6, linksys wusb54gc ver3 wireless-g

Postby pingpong » 2012/09/23 15:36:18

I have a problem installing the wireless network USB adapter on CentOS 6 on my home computer. There is no driver for Linux, but Windows.

Is there other ways to install the adapter?

Thank you in advance!!

Hi,

Thank you for your advice. I tried that, it seems it can recognise my USB network adapter.

Code: Select all
# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 004: ID 1737:0077 [color=000066]Linksys WUSB54GC v3 802.11g Adapter [Ralink RT2070L][/color]
Bus 002 Device 002: ID 045e:0750 Microsoft Corp. Wired Keyboard 600
Bus 003 Device 002: ID 045e:0039 Microsoft Corp. IntelliMouse Optical
Bus 001 Device 012: ID 1b1c:1ab1 Corsair

I am wondering what I should do to install it.

Thanks in advance!

Thank you for providing that information. The really important part of that line is the Vendor:Device ID Pairing, [color=FF0000]1737:0077[/color], which precisely defines the required driver.

The first thing to do is to check to see if there is a module available in the distributed kernel --

Code: Select all
[ajb@Duo2 ~]$ grep 1737 /lib/modules/*/modules.alias | grep 0077
/lib/modules/3.5.4-1.el6.elrepo.x86_64/modules.alias:alias usb:v1737p0077d*dc*dsc*dp*ic*isc*ip* rt2800usb
[ajb@Duo2 ~]$

Unfortunately there is no mention of a distribution kernel, above.

So let us look elsewhere to see if there is an installable kmod package which will provide the driver. We go to the Device IDs page at the ELRepo Project's site and check for 1737:0077. Unfortunately, once again, there is no mention of that Vendor:Device ID Pairing on the page.

So it does look as if you will need to read-up about the kernel-ml package that is also available from the ELRepo Project and consider installing that kernel to obtain support for your USB wireless adaptor.

Hi,

Thank you very much for your advice and help.

I am a Linux newbie.

You said in previous post:

How difficult is it to do that? I never did that before.


I found this to run windows driver on linux?

Using Windows drivers - ndiswrapper on the link below

http://wiki.centos.org/HowTos/Laptops/Wireless

On the link, it mentions:

, set up the ELRepo repository


Does it need a network connection, which I only have on Windows?



Thank you in advance!

Let me expand on Alan's statement for you. :-)

He is suggesting that you try installing kernel-ml which is the latest version available from kernel.org that was rebuilt to run on Enterprise Linux including CentOS.

First, you set up the ELRepo repository by running (as root):

Code: Select all
rpm --import http://elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -Uvh http://elrepo.org/elrepo-release-6-4.el6.elrepo.noarch.rpm


Then you install kernel-ml by running (as root):

Code: Select all
yum --enablerepo=elrepo-kernel install kernel-ml


Reboot the machine. When you get the grub menu, select the newly installed kernel. It must be at the top of the list and has elrepo in the name. Boot it and see if your USB wireless now works.

Hi,

Thank you for your advice.

Could I double check one point:

Because the wireless network adapter is the only device in CentOS, which is not working. And the commands you showed me require internet connection. I guess I need to download those two files, store in a USB flash drive, and then run those two command to install it.

Thanks again.

Indeed. You need to do it that way.

Download this file:

http://elrepo.org/elrepo-release-6-4.el ... noarch.rpm

Locate a mirror site near you by checking the Download page. Then download the kernel-ml file.

kernel-ml-3.5.4-1.el6.elrepo.x86_64.rpm (if your system is 64-bit)

kernel-ml-3.5.4-1.el6.elrepo.i686.rpm (if your system is 32-bit)

Once transferred to your CentOS box, installed them by a 'rpm -ivh ' command.
