I have no other complaint of this product except the PPPoE dialup is too slow comparing with other wireless routers I have used. In my experience in Linksys, it takes just seconds to complete the whole login authentication process. However, in DGL-4500, not less than 40 seconds it needs. The worst case is after the router reboot, even the cable connection is detected, I still can't login successfully until minutes later. Since I never encounter similar problem in other products, so I am sure this is the product issue; only I have no idea if this is a bug which overlooked by most of us, or this is the common product behavior.
