dlink dwl-g820 needs unplugged replugged in (rebooted)

Hi there.. I use the dlink wireless gaming adapter with my xbox.. for
some odd reason.. it needs unplugged and plugged back in (rebooted)
every so often (every 2 days or so ?). I dont use any encryption as of
now.. I do have a Dlink DI-784 router (I have used a netgear wgt624v2
in the past too.. same thing occurred). I'm running it at superg 108
mode.. As of yet I havent tried backing it down to 54 on a different
channel..

has anyone else experienced this?

Thanks
