firstly I'm new to Ubuntu. Well my problem is I have RTL8187L Wireless USB adapter and I'm using Ubuntu 10.10.However, stock driver shipped with this Ubuntu won't work with my adapter. It detect the device and allow me to connect to AP but after 10 seconds, it will disconnect itself. So I went to Realtek website, download and install the new driver. However, after restart Ubuntu can't detect my adapter anymore. How can I fix this problem and where can I find suitable driver for this adapter. Please help me expert...

maybe the old driver is now blacklisted instead of replaced or they are now both blacklisted...check /etc/modprobe.d/ for anything relating to your wireless card. – Call me V Apr 27 '11 at 1:15
I've got it to work after following some tutorial on net however same problem happen.It can found wireless signal, connect to it but can't browse the internet. Even ping to google won't do. – AngryCrow Apr 27 '11 at 1:24
I would look at this: aircrack-ng.org/doku.php?id=r8187 – Call me V Apr 27 '11 at 2:47
specifically at the end: On recent kernels, the patched driver fails to work in normal WPA/WPA2 mode. In this case, use the patched ieee80211 driver for injection and use the mac80211 version for normal WPA/WPA2. In order to do this you will have to blacklist the unwanted module based what you plan to use your system for. IE For injection, blacklist the rtl8187 module. For WPA/WPA2, blacklist the r8187 module. – Call me V Apr 27 '11 at 2:50
