Right, done some testing (Online Gaming
) and this is what i did, used reset button, then turned off ipf and fwall, then changed upnp hoops from 4 to 11, had no router connected, just PC and PS3, and it worked for hours, so plugged my router in and put all PC though the second router, but PS3 still through SH Wifi, worked for about an hour, then had the same GT5 probs, so i unplugged the router, still nothing, Reset SH and it worked again,
anyway looks like i can live with this for now, tho i would still like a modem as then theres no dodgy box with an intermittent fault, yes it will probably be replaced on monday (vm comming out) but i know it will be the same because netgear routers are like choc fire guards, just hope they get the modem update right if i dont get a modem
