[Northeast] New MI424WR GigE Rev I doesn't recognize my DLink Sw

I went to hook up my new FiOS MI424WR Rev1 GigE Wireless N Router that I bought from Verizon. My current one MI424WR Rev E has a cat 5 cable that runs from the second floor down to the first floor to a Dlnk 8 port switch and hooks up 2 PC's. They have internet access. After hooking up the new MI424WR Rev1 GigE Wireless N Router, same way as the MI424WR Rev1 GigE, it didn't recognize the ethernet cable that's connected to the switch. After spending 2 hours with both Verizon and Actiontec, Actiontec blamed the swtich. After telling the Actiontec it's not the switch because it works fine with the MI424WR Rev E he hung up! Any one have any thoughts why the MI424WR Rev1 GigE doesn't recognize the swtich?
