Revision history [back]

Description:

I updated to 1.0.3.8 and am using a wpa enterprise network to connect to. This worked fairly fine until today when the connection suddenly ceased. The last i did was downloading a disk image and when i after 5 minutes tried to look something up with the browser i had no internet connection and was told the website is not available. I checked the network connection and ifconfig did not show an ip address assigned. After some minutes the connection was reestablished and back to normal.

Here my wpa config:

[root@localhost nemo]# cat /var/lib/connman/wifi-company.config 
[service_company]
Type=wifi
Name=Company
EAP=peap
Phase2=MSCHAPV2
Identity=username
Passphrase=password

Here the snippet from dmesg:

Howto repeat:

Connect to some wpa enterprise wlan with above settings and download some big file (> 500mb) repeatedly and see if your network fails eventually. run 'dmesg' as root to see the oops message.
