Here's the situation:
speedtest.net wont load
Grabbit gives connection errors to VM news server
SABnzdb wont download from VM news server, but tests the connection as OK
I can ping news.virginmedia.com
Flash based websites are hit and miss
Have messed around and found if I loose the netgear WNR2000 and connect direct to the modem everything works OK.
Connected up an old dlink (DI-524) and everything works OK.
Flashed WNR2000 from netgear firmware to DD-WRT and problems remain.
Any suggestions? (Apart from the obvious 'Get a superhub' reply I've opened myself up to!!)
