bad link quality when using madwifi drivers for eee pc

Description

When I use the madwifi driver (madwifi-nr-r3366+ar5007.tar.gz) on my eee 900 the wifi range and link quality are incredibly weak. Sitting three feet away from my router iwconfig reports the link quality to be around 40/70. I have observed similar performance problems when working at several other routers. At first I thought my wifi card might be defective, but other people on the eee forum also seem to have this problem. When I installed the windows xp driver with ndiswrapper the link quality and range improved significantly. I had windows xp installed on the machine for a short period of time and the wireless performance was on par with when I had been using ndiswrapper. I use ubuntu, but I have had the same issue with different distributions using the madwifi driver.

This version is outdated, you should follow the instructions on #1192 instead to get a more up to date version of MadWifi for your system.

The link quality reading is no fraction in MadWifi. The first value is RSSI, the second is the noise level. It seems that you're in a very noisy environment, but still 40 is a good value. See also UserDocs/RSSI for more information.

That is interesting. I always thought that was some fractional value for the amount of packets that made it intact. The second value never seems to change though, it is always 70. The first value drops rapidly as I move away from my router. If I use ndiswrappper, the link quality is shown as x/100.
