Network manager internet problem with eduroam.

I'm connected to eduroam on my laptop. After like 20-30 min the internet connection is gone. I have to restart NetworkManager to get it up and running again. I checked the journal and the NM tries to connect to eduram after the lease expires but after it connects the lease time is set to 28 min. After that im connected to the wifi but no internet. Any Ideas?

Re: Network manager internet problem with eduroam.

I've made good experiences configuring NM to use dhclient as the DHCP provider instead of the built in one: https://wiki.archlinux.org/index.php/Ne … HCP_client
