FW: Fedora 7 0.6.6-1 reconnect issue?



I am not sure if this made it to the list or not as I didn’t receive any replies.   This behavior is killing my network now.  I get abour 40-50% signal strength but the connection drops everyone so often and when it does the below situation occurs and I don’t get a reconnect.   I am pretty sure this must be a bug in 0.6.6.   (As a side not I think the behavior in the situation in 0.6.5 was a seg fault but I had a swatch script that watched for NM crashes and restarted the service and hence the connection).

 

Thank you in advance for your help and time!

Hello,

 

I am using Fedora 7 with a kernel (modified) based off of Fedora 2.6.23.15-80, madwifi drivers, and NetworkManager 0.6.6.

 

The scenario is thus:

 

  1. WPA-PSK/TKIP connection established to SSID1
  2. Numerous Supplicant state changed: 0 then 1, over and over again.  (I assume this is connection yo-yoing).
  3. Eventually the connection times out.  (ath0: link timed out.)
  4. SWITCH: found better connection SSID1 (for the same connection that was just lost)
  5. DHCPRELEASE on the connection is started
  6. Activation started
  7. During Stage 2 configure a DHCP daemon state is now 14 event is received.
  8. real_act_stage2_config()  :  couldn’t connect to the supplicant.
  9. Device deactivated

 

I have repeated this a few times now.  I suspect that the normal exit event from DHCP is scheduling a failure during the activation of the new connection which somehow kills wpa_supplicant.  Am I even close on this one?  Below is the messages log I saw.
