Got my shiny new VZW NE yesterday, set it up, got 3 blue lights but the SYS light flashes(slowly) red. Hmmm. I have link and activity on the WAN LED and the RJ-45 on the back of the NE.
Troubleshot it myself for a while. Set up a MAC/DHCP IP reservation and forwarded all the suggested ports.(Since the NE uses IPSEC NAT transversal (judging by the port numbers) it should not need ports forwarded. I will check with my ISP to see if they block any of those ports for some reason.) Nothing. At that point I called tech. support. They had me ping a VZW site, put me on hold a few times, gave me a ticket number and told me that it could take up to 72 hours for resolution.
In the meantime, I completely bypassed my router and hooked it directly into my cable modem. Rebooted cable modem to learn NE MAC and assign an IP address. Nada.
Just for ha-ha's I hooked it into my Vonage router ( I get 2 WAN IPs from my ISP). Nada.
I checked "My Network Extender" and they do have my MAC address properly registered to my account.
Eliminated all the easy stuff, patch cables, etc.
Have the GPS on the extender cable with a clear view of the sky. Locks on in a couple of minutes.
I'm guessing that the problem is on VZW's end or the NE is simply defective.
