Ubuntu

New install of of Feisty; Wireless no longer works

Asked by Michael Ortenberg

I had been running Edgy for over 6 months, when I decided to take the plunge and upgrade to Feisty. The upgrade hosed the entire computer, so I did a fresh install. Since it didn't import any old settings, I am starting from scratch, but with exactly the same hardware that I had for Edgy.

The wireless card I have is not detected, even though the driver is installed. I have read enough posts to know that my wireless card requires ndiswrapper to work in Ubuntu.

The card is a TrendNet TEW-423PI, revision B1. I installed the latest drivers from the TrendNet website (mrv8000c.inf). This appears to use the Marvell Technology Group Ltd. 88w8335 chipset, based on the output of lspci (see below). Note: after I completed all listed below, I repeated all steps using mrv8335.inf, based on a post on this forum for a different card with the same chipset, with the same result. The result is exactly the same - no wireless connectivity.

Here's what I did:
1. Installed wireless driver using ndiswrapper following the instructions here
rhianna@rhianna-desktop:~/Desktop/Rhianna$ sudo ndiswrapper -i Mrv8000c.INF
Installing mrv8000

2. Confirmed installed drivers
rhianna@rhianna-desktop:~/Desktop/Rhianna$ sudo ndiswrapper -l
Installed ndis drivers:
mrv8000c driver present, hardware present

3. Per instructions, made drivers install automatically
rhianna@rhianna-desktop:~/Desktop/Rhianna$ sudo depmod -a
rhianna@rhianna-desktop:~/Desktop/Rhianna$ sudo modprobe ndiswrapper
rhianna@rhianna-desktop:~/Desktop/Rhianna$ sudo ndiswrapper -m
Adding "alias wlan0 ndiswrapper" to /etc/modprobe.d/ndiswrapper

4. Went to System | Administration | Network, but no wireless card appeared

Any ideas?

Thanks!

Thanks very much for the link.

I just used link (https://help.ubuntu.com/community/WifiDocs/Device/TRENDnet_TEW-421PC_H/W%3aB1_%28ndiswrapper%29?highlight=%28WifiDocs%2FDevice%29) which outlined steps to uninstall ndiswrapper, download the latest version (1.44), download the latest device driver, and install all.

I followed every step as written. However, when I get to Step 6 - Install the device and configure the network settings, what I see on the screen is different from what is being illustrated. My output of iwconfig yields only lo and eth0 - there is no wlan0 output.

Every other step showed success, including that the driver is loaded and the hardware is present. I know it's functioning, because before I switched to Feisty, it was running fine in Edgy.

Any other suggestions??

Thanks!
