Input:
I just purchased the Linksys BEFCMU10 ver 2 and replaced a Toshiba modem that I was renting from Cox.  I literally opened the box, set up the modem, called Cox to update the MAC address and serial number for the new modem, and was back online within 15 - 20 minutes.  I connected my pc directly to the modem to make sure it was working, and everything was ok.  I didn't lose any speed by changing from the Toshiba, and I may have gained a little.  Next, I powered down the modem, connected it to my Linksys Wireless Cable/DSL Router, powered both units, and once again, I was back online....wireless mode now.  This unit is much smaller and lighter than the Toshiba, but I am very happy with the purchase.
