Eduroam troubles. Networkmanager, intel wifi.

Hey everyone.
Usually, I am able to dig through sufficient information to isolate the issue and find a solution, but this time I'm truly lost about what's happening here.

I am trying to connect to eduroam at my university. The official guide says that both PEAP + MSCHAPv2 and TTLS + PAP is supported, and this issue happens in all configurations.

I have OS's installed on my laptop: Arch (HDD), Windows 8 (HDD) and recently Arch on my new mSATA SSD. The network works perfectly in both of the "old" installations from the HDD, but not in the new Arch installation. I can authenticate fine to the network, but I have no working connection. The unprotected network works.

It seems that something is happening in my installation the moment I connect to eduroam that stops it from working. This ping tests shows something interesting:

ping: sendmsg: Network is unreachable
ping: sendmsg: Network is unreachable
64 bytes from 8.8.8.8: icmp_seq=823 ttl=56 time=39.9 ms
64 bytes from 8.8.8.8: icmp_seq=824 ttl=56 time=19.8 ms
From 10.16.140.18: icmp_seq=864 Destination Host Unreachable
From 10.16.140.18: icmp_seq=865 Destination Host Unreachable
From 10.16.140.18: icmp_seq=866 Destination Host Unreachable

The first two are before the network is done authenticating, etc.

Then, the first second or two, there's a connection, but then it stops working, and I can reach nothing, not even the network DNS server or the standard gateway.

So... Something is running some kind of setup script the moment the authentication is done, or some kind of buffer clogs up. But I have not been able to locate any errors in dmesg, journalctl or what else I know of to check:

dmesg:

Any ideas?  :-/

Thanks!

I haven't been at the university since friday, but I'll have a look and see if I can manage making it work. :-)
