This mornings connection issues were pinpointed, or at least suspected to be a router problem your end, it wasn't just me who experienced the exact same problem so I can discount something wrong with my own setup/network.
As for my FTP problem, I unchecked PASV a few weeks ago after getting a wireless router and ADSL connection. Until today everything was fine.
My FTP problem seems to be happening with non FQ domains as well, so its something to do with my network or something else, but why it should start today I really don't know, nothing has changed on my system.
Thanks for your help anyway, I'll have to do some further digging and find the problem.
