Networkmanager have problems with PEAP/TKIP
Last modified: 2008-10-20 11:10:03 EDT
Description of problem: Networkmanager disconnects after some time using TKIP. Sometimes its possible to reconnect after a restart of NM. There is no option in the menu to choose TKIP. (I compare with for example Ubuntu 7.04-10 where TKIP is an option) Version-Release number of selected component (if applicable): NetworkManager-0.7.0-0.6.7.svn3204.fc8 [root@wallence ~]# lsmod |grep iw iwl3945 161461 0 mac80211 125265 1 iwl3945 How reproducible: I don't know, maybe try a WPA-Enterprice WLAN with PEAP and TKIP? It is hard to say since uptime seems to vary from time to time. Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: [root@wallence ~]# iwconfig wlan0 IEEE 802.11g ESSID:"PORT-ADM" Mode:Managed Frequency:2.437 GHz Access Point: 00:1A:30:33:41:80 Bit Rate=54 Mb/s Tx-Power=16 dBm Retry min limit:7 RTS thr:off Fragment thr=2352 B Encryption key:208D-6D08-76C6-687C-5C38-7CB8-12BF-8432-2C71-1350-9122-BC6F-9D07-3EB5-0A22-CC1E [2] Link Quality=86/100 Signal level=-47 dBm Noise level=-85 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 [root@wallence ~]# iwlist wlan0 encryption wlan0 2 key sizes : 40, 104bits 4 keys available : [1]: off [2]: 208D-6D08-76C6-687C-5C38-7CB8-12BF-8432-2C71-1350-9122-BC6F-9D07-3EB5-0A22-CC1E (256 bits) [3]: off [4]: off Current Transmit Key: [2]
Is your access point hiding it's SSID? Can you provide "/sbin/iwlist wlan0 scan" output for your access point? I need to see it's WPA/RSN information elements. If the AP is properly advertising it's capabilities, then wpa_supplicant should be able to automatically choose the correct cipher suite for the AP and you should not need to set that manually. Thanks!

Comment on attachment 303454 [details] Log from NetworkManager Report: I can now connect to my network but I get disconnected after awhile. I can reconnect a few times but after awhile I need to reboot NM to get going again. I send some logs that I hope can help.
Created attachment 303479 [details] At the end of this log NM is trying to connect several times and at last i succed Additional information: This log shows how NM tries to connect, fails several times and then succeds.
Networkmanager. Hello, just after I reported problems I got an update and it now works much better. Some of the problems still occur, sudden disconnect and I have to try twice sometimes to reconnect. Please tell me if I can be of some help to improve NM further. Maybe it would be better if it said TKIP instead of peapv0? I wasn't familiar with that anyway that they were the same. Best regards, Micko
Created attachment 305484 [details] messages from NM F8 and NM F9 At the end of the file there is output from NM in F9. Sorry if its to big. At the start of the file there is output from NM in F8 working okey.
Comment on attachment 305484 [details] messages from NM F8 and NM F9 Short report of NM F8 -> F9 I upgraded yesterday. The latest NM in F8 was working perfect on my WLAN. The new in F9 (that look really promising, nice work!) is not as stable. It disconnects more often and I have to restart it to make it reconnect. I include a logfile and hope it can help. Thanks! (I dont really know what is affecting this, maybe off cource, its something else)
Is this still an issue with latest NM, kernel, and wpa_supplicant? WPA/WPA2 + PEAP/MSCHAPv2 tested fine with NM svn4022.4, 2.6.26.5-28.fc8, supplicant 0.5.10-6.fc8. Please re-open if it's still an issue.
