XB6 Modem in Bridge mode, to switch, Netgear router plugged in, won't connect to internet
So bacially I put the Xb6 modem in bridge mode, from the back of the modem (hopefully the right port) I plugged a wire into a gigabit switch. Then plugged the Netgear router into the switch. The wizard was not able to set up the connection. Any idea why?
Also is it ok to have two router plugged into the switch which both use the 192.168.xx naming scheme?

Question. Why do you need a switch hung off of the the Comcast gateway in bridge mode ? In bridge mode it acts like a plain vanilla cable modem and you will only get one single WAN / public IP address in bridge mode. In router mode, you will get all of the private LAN IP addresses that you need.

My idea was to plug two seperate routers into the switch, one for upstair and one for downstairs (I want 2 seperate networks). But this idea won't work.
The cable from the modem/router in bridge mode must go directly into another router.

Of course it won't work. You can't have two separate routers connected to what essentially is now a simple modem, i.e. a gateway in Bridge Mode.
What you need to do is enable router mode on the XB6, but disable DHCP and NAT. Same with the other two routers you have connected to it, which then means you will have to go the painstaking work of setting up the subnets on each router.
If you don't have a switch that can create a virtual LAN (VLAN) or a subnet, then you will probably need something akin to the "three dumb routers" solution Steve Gibson forumlated. You can look at this link for instructions on setting it up.
