Trouble setting up wlan interface

[Tweek3d920]

Hi, I am running into a strange problem when I try to set up my Trendnet TEW-424ub device. I downloaded and installed ndiswrapper, installed the drivers to it and ran the modprobe command but the wlan interface still doesn't show up. I ran the lsusb command and it says driver present and devie present but still no interface. Please help!

Please post the output of these commands:

ndiswrapper -l
lshw -C Network
lsmod | grep ndis
dmesg | grep -e ndis -e wlan

Ok, here's the results of ndiswrapper -l

net8187b : driver installed

Thank you for your help!

It looks like ndiswrapper doesn't like the Windows driver that you loaded into it. Sometimes this happens. First, remove the Windows driver that you have currently installed:

sudo ndiswrapper -r net8187b

Then install a better driver. According to the ndiswrapper site, these are links to ones that should work for your card:

http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=1&Level=6&Conn=5&DownTypeID=3&GetDown=false&Downloads=true used winXP driver contained in RTL8187B_logo_6.1074.0406_silent_install.zip

Also remember that if you're using 64-bit Ubuntu, the Windows driver needs to be for 64-bit Windows.
