Hi, I have installed a brand new Belkin Pre-N router that I use with a variety of network cards: Belkin 54g, MN-720 54g, some other USB products 11b. I use both XP SP2 and W2000, and the router configuration is left standard except for security handled through MAC Address restrictions. While this router really rocks, on a weekly basis I have this phenomenon where the wireless connections drop in performance and finally get dropped without any warning. It seems like the router gets overloaded and cannot handle wireless connections while cable connections remain active. The only way I have right now to restore the situation is to either switch the router off, or resetting it through the configuration software. After that operations things get back to normal at full speed. Does any one has a clue about that issue? I checked the Belkin web site unsuccessfully. It really bothers me because this router really expand my signal range great, beyond my expectations.
