I have a DDR2200 just installed by Centurylink for a bonded pair DSL. It feeds my home network through a Netgear JGS524 Gigabit switch. The DDR2200 locks up at random times. A Centurylink tech told me that the switch was causing the 2200 to lock up. The 2200 has only four ports and I need a minimum of 16. He also told me that any switch would do this. Can anyone confirm this behavior and/or have a solution?
