Hi.
Im setting up wireless bridge uning internet sharing:
AP --wireless--> openSUSE laptop -- ethernet--> windows PC.
using network manager to connect to my campus wifi. login management is using cisco web auth. I believe most of us familiar with this login web interface:
![]()
But soon after everything set up and running, I noticed my the session keep deauthenticated, like every 15 minutes or so. Sometimes not even 5 minute. Then it redirects me to login page again.
Even if I managed to re login, most of time the connection will degrade to the point it barely transfer any data if at all; and it will only return to normal speed if I manually disconnect the wifi and reconnect again (and the cycle continues).
Seems like some 'bad packet' has triggered deauthentication.
This problem had never happen when I used windows, both on laptop(ICS server) and PC (client). My wifi session can sustain for 7-8 hour before getting disconnected for intended session timeout.
Suspecting linux side as culprit, I swap the role; With laptop running as windows, and PC running as openSUSE. And it still happen. Means the 'bad' packet must be coming from openSUSE.
Then I tried disabling the network manager in yast; and instead, I use the traditional method using ifup. This time it work. I never get any deauthentication nor network degradation anymore.
So I conclude that it was network manager that keep bugging the wifi auth.
Abandoning network manager leaving me with side effects and question.
1 - I cant connect to openVPN server. Seems all the client available was made to work with networkmanager. Is there any (easy to use and install) GUI openVPN client that doesnt build on top of network manager?
2 - Is there any way to connect wireless without using network manager? I really wish I can use openSUSE as my ICS server.
3 - Is there any way to diagnose the exact problem that trigger the deauthentication in network manger?
Thanks.
