WM,
Had this problem here in Astan...I fixed by checking my guys' stuff to make sure there was no security ie WEP or some other form highlighted in the wireless config. Go figure the delta has to fix commo
If the router is just used as an open network just make sure you don't have your wireless configs trying to use wep or something like that. That should solve the problem...if not pm me and I'll try and get back to you! Good luck!
