As it says in the title, I have 14.04 installed on a 2009 5,5 MBP and the wireless sporadically disconnects from one specific wifi network; Eduroam. The disconnects are not after a set period of time and they appear to follow no pattern.

For the unaware, Eduroam is the wifi network used at the majority of universities in Europe, and many around the world. I have tried connecting at both my university and three other universities that I have visited recently. This has only been a problem since the beginning of this term. I have no problems connecting or maintaining a connection to any other wireless network.

I have tried this answer in another thread: https://askubuntu.com/a/60395/350115

The output of: lspci -nn -d 14e4:

gives: 03:00.0 Network controller [0280]: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b] (rev 01)

Which did not show up in their list and thus I used the [14e4:432b] as the closest in the list and installed bcmwl-kernel-source

This has made no difference to the problem. I also set IPv6 to ignore, and this was also fruitless.

I don't know how to debug this connection, and it is very annoying.

The output of dmesg after a disconnect ends with:
