Small comment. I am not sure if this is true of the ubuntu package, but I hear the signal strength in the madwifi driver is "out of 62" as opposed to out of 100 so when network manager reports 60 that is close to 100 percent.
A patch was proposed to fix this just for the madwifi cards but as far as I know it was not included within the official network manager source, but instead left to individual distributions to apply it if they want to. I found the discussion on the mailing lists about this (patch written by robert love). However, the issue I experience is actual low signal even taking into account this "bug" with madwifi reporting. -- Atheros WLAN (MadWifi) poor signal strength https://launchpad.net/bugs/66481 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
