I type this from the LAN connection of the WBR-2310 because the wireless connection has coughed up and quit. Again. This router requires constant attention. I have upgraded the firmware twice and still there are bugs. One bug has even been introduced by the latest firmware. MAC filtering no longer works after the latest update. The router requires physical rebooting at least once per session. It assigns IP addresses that are not in the allowable IP string, thus disallowing the connection. When it drops my connection, it must be physically restarted before allowing me to connect again. It's a horrible waste of time and money. I will never, ever own another D-Link product. I have owned and operated Linksys, Netgear and D-Link routers. D-Link is the worst by far. Buyer, beware.
