New Verizon FIOS router screwed up my network

[lozina]

So I've had Verizon FIOS internet service for a couple of years now. They provided me with a D-Link router so it was easy to setup my netowrk at home. I gave a few PCs a static LAN IP and then set a range for DHCP IPs for the rest. This worked very well and I never had a problem accessing one machine from another.

Fast forward to today and the guys at Verizon set up the TV service at my house and they replaced the D-Link with some new router. (pdf user manual) and this thing apparently tries to abstract much of the details away leaving me plain confused. Computers in my network can no longer communicate with eachother. For example one PC got an IP address 192.168.1.100 and another got 192.168.1.101. When I try to ping one another, nothing happens. Also, they cannot see eachother on "My Network places".

I cant find anything in the configuration of this thing that would seem to solve this, except for one general "firewall settings" screen which I set to minimum.

anyone else have this thing and know why it's blocking communication between my PCs?

YOu may have to re-run the network setup wizard. Or try disconnecting you TV service from the router, then trying to ping.

Can always break down and call verizon.

Did you set all the PC's back to DHCP? Did they take the other router back? If not, just throw that back on, you dont need to use their router if you dont want to(i think)

Unfortunately I do have to, it is some special router with a coax connection in the back. Apparently the Set Top Boxes for each TV communicate with eachother and the Verizon network through the coax cables through the router. My old router has no such coax connection...

Initially the router they put in was set up for DHCP in the full ip range of my LAN. I changed this to reflect my old network setup where 192.168.1.1 - 192.168.1.100 was reserved for static IPs which I may assign to things such as my server or my printer while everything above that could be DHCP for the rest of the devices I plug in.

The IP addresses look good on the machines, no conflicts, the DHCP range is setup correctly, but NO computer can see ANY other on the same network
