Oh man, I just had this issue a couple of days back.Something's bugged about the RTL8185 drivers in the kernel (no, you shouldn't have to install anything extra, just modprobe it). Check out the Wiki page: https://wiki.archlinux.org/index.php/Wireless_SetupTry following the instructions there (use rtl8180; the drivers for rtl8180 and 8185 are merged).
I am trying to install wireless network drivers but I couldn't find any driver for wireless under network drivers. I just installed ubuntu 9.10 today but my wireless is not there. I am able to connect through wire but not wireless.
