After updating wpa_supplicant my wireless network is really unstable
Last modified: 2007-11-30 17:12:20 EST
Description of problem: After i updated to the latest wpa_supplicant, my wireless is really unstable. And sometimes NM doesn't find any networks. If it does find it and i connect, the speed is really poor. It should be 54Mb/s, but when i checked in NM it says 1Mb/s or 9Mb/s. It seems like the connection hangs and the suddenly the speed increases and then it "stops" again. And this happened when the wireless AP was 2 meters away. NM-applet also crashes more often. Version-Release number of selected component (if applicable): kernel-2.6.23.1-41.fc8 wpa_supplicant-0.5.7-15.fc8 (unstable) wpa_supplicant-0.5.7-13.fc8 (everything works ok) How reproducible: Every time Steps to Reproduce: 1. Start up with wireless 2. 3.

The wpa_supplicant patches should only affect WPA-EAP and Dynamic WEP code paths. What encryption and authentication are you using?
I use wpa2-psk.
I updated wpa_supplicant (and other packages from koji) and did several reboots. And now it works as it should. So there might have been something weird going on when i tested it earlier. So this is not an issue anymore. But nm-applet still crashes often when i click "connection information". Mine is translated into norwegian bokmål. This error keeps popping up in every bugbuddy-report: (nm-applet:3944): Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text()
I've been trying the latest NM-snapshots in koji, and all the problems i reported earlier have gone away. :) So i'm closing this one.
