This is an unusual post but it might help few people who are trying to set up Wi-Fi connection with a Belkin F5D7051. This was tested on Ubuntu 11.10 32-bit.
During the installation of Ubuntu, the Wi-Fi has been successfully connected but after rebooting: no network interface (
wlan0). This is due to a conflict between 2 modules:
rndis_wlan. In fact, there are 2 types of F5D7051 based on the Broadcom BCM4320 and Ralink RT2500USB chipsets. The problem is that both have the same ID
vendor:product that is to say
050d:7051, so the kernel could load the wrong one. Here are the steps to fix the issue.
The following solution is to blacklist the wrong module.
First of all, ensure that you have the right component by typing in the terminal:
It should display something like:
Bus 001 Device 003: ID 050d:7051 Belkin Components F5D7051 802.11g Adapter v1000 [Broadcom 4320 USB]
050d:7051 is the unique identifier of the component and
[Broadcom 4320 USB] is the based chipset. Then, check loaded modules with this command:
If you see both modules:
rndis_wlan, edit the
/etc/modprobe.d/blacklist.conf and add the following line at the end of the file (to edit you need to be root; if you have a Ralink chipset, replace
Then, unload the module by typing in the terminal:
sudo modprobe -r rt2500usb
Finally, save the file and reboot the computer. Hope it helps. :-)
