Router problem - dropping the connection

[samthemaster]

hi, i have a Zyxel Prestige 660HW-61 router. this is no good for xbox live due to the NAT settings.

i bought a new router - a Netgear DG834G. i set up the router with my pipex isp username and password. the router worked but after about 5 minutes the router dropped the connection. i have upgraded the firmware to the latest version and have tried downgrading also.

the problems are the same, the router loses the internet connection after 5-25 mins. restarting the router sometimes brings it back but sometimes doesnt.

i really dont know what to do next, so does anyone have any advice as to how i can get this damn router working.

thanks.
