definitely need improving. Here what I see after 5 days:
first time set up was so easy. It reconigned my cable modem and ran right away. The problem started when I turned off the pc. One the pc (Win XP) turned back on, it could not get the DHCP address from the router so of course no Internet connection. Had to repower off router, modem and pc in this order for it to work. Try it several time and got the same symtom. Upgraded firmware still not resolve the problem. Still can not get tech support because i was on hold for too long.
