I also noticed the strange signal behaviour and sudden disconnects. I compared the strength of several accesspoints nearby and it looks like madwifi or network manager reverses the signal strength. Under Windows I usually have nearly 100% and under Ubuntu nearly 0%, and disconnects when it hits 0%. When I look at the accesspoints nearby I can confirm this behaviour. I have listed the AP's nearby and I sorted them on signal strength under Windows XP and Ubuntu 8.10. The list of Ubuntu is almost and reversed one compared to the XP-list.

I think reversing the signal-strength should be an easy fix (although I don't no where exactly to look) and it could possibly resolve a lot of weird disconnects (with "full" -> actually bad strength). A work-around I currently use is bending my antenna for some less reception and NetworkManager doesn't hit 0% (which is actually 100%) so I stay connected. My system uses a Realtek 8185 (module rtl8180). Maybe others could check and possibly confirm this behaviour. ** Attachment added: "wireless-strength.png" http://launchpadlibrarian.net/19488288/wireless-strength.png -- atheros wifi card drop connection and low signal https://bugs.launchpad.net/bugs/94148 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
