WLAN: RTL8191SE-VA2
OS: Linux Mint 9 (64-bit), dual-booted with Win7 Home Premium/64-bit
Problem:
Have tried (literally dozens of) solutions posted here and on the forums for distros related to Linux Mint, and nothing seems to work. WLAN0 is seen, but not usable. The one time it did light up (this is peculiar!) I wound up in Ad-Hoc mode with a 10.x.x.x IP, when I was trying to get it to see my access point (Netgear DGN2000) and its DHCP.
I suppose my big question is this: How do I properly resolve this, since nothing seems to be working... in Linux Mint. I've already noticed that Linux is far less power-guzzling than Windows, which (as an author who is out and about quite often) is a good thing. In Windows, the WLAN card works fine, so I think my frustration with this issue is (somewhat) understandable. While I am not a Linux newbie (in fact, currently working on Linux Admin exam), it's been years since I really delved into it, and that's probably part of the whole issue.
Also trying to find the fan-control subsystem, as the laptop doesn't seem to be managing fan at all under Linux, which is odd.

Problem solved via upgrading OS to Linux Mint 10. LM10 recognized the card out of the box and it's been working ever since.
Not that I blame it.
