My university uses a VPN system for internet connections. A couple of days ago I installed 12.04 on my computer and set up the VPN following a guide specific to linux here. It would work quite well, but disconnect every now and then, especially when I checked for new updates. After a few reconnections however, it would become stable until I powered down the computer.
On upgrading to 12.10 , the VPN would connect and then fail instantly whenever any network activity was attempted (checking for updates, loading a web page etc). I have now reverted back to 12.04 with a fresh install.
So I guess what I'm asking for is a bit of help as to what I should do next. Reinstall 12.10 and see if the issue disappears? Visit the university's IT helpdesk? My VPN settings are exactly the same as on their guide.
The VPN worked flawlessly with Windows installed. The computer is a HP dc7100 SFF.
Any help would be much appreciated
Thanks in advance
