Comment 212 for bug 401126

Just purchased an Asus 1201N and installed Ubuntu 9.10 amd64 on it. I too have been running into non-stop problems getting wireless working. First I tried the ndiswrapper driver, but as it's 32bit and my OS is 64, it wouldn't load. I found this thread and tried all the various modules and patches, but still had issues. The same everyone else had. Never had the system crash, but I did have issues not getting it to boot up, taking a long time, finally getting it working but it would only stay connected for about 10 seconds to 10 minutes. On occasion I could stay connected longer, but couldn't disconnect and reconnect to the same or a different AP without unloading and reloading the module. This morning I tried the rtl8192se_linux_2.6.0014.0115.2010 version, but first making the DENABLE_LPS changes. That resulted in even more problems. I was about to give up and replace the wlan card, but figured I would give it one more try.

So, I uninstalled everything, and recompiled the rtl8192se_linux_2.6.0014.0115.2010 module WITHOUT MAKING ANY CHANGES.
sudo -s
make
make install
modprobe r8192se_pci

Viola.

No more disconnects, no more weird kernel messages, no more problems period. I've even shut off the wireless via the keyboard and network manager, re-enabled it, and immediately connected. Tested on open, WPA and WEP networks. Can even transission between them perfectly.

I think we've finally found a viable solution.

So if you have an Asus 1201N running Ubuntu (especially the 64bit 9.10 version), I highly suggest you try this method.

If I run into any further issues, I'll let you know. But it looks like smooth sailing.
