Bridge or Router?

[Bill_S_1]

Netgear modem port connected to WAN port of a Netgear router. Router DHSC is set to on. Seems to me that "Bridge" woyld be correct. (modem default setting is Router).

Should I change it?

OK, thanks Gordon. I was going to leave the modem DHCP on, turn the wifi router DHCP off, and move the CAT cable from the WAN port to a LAN port, but since this double NAT doesn't seem to matter, I'll just leave everything set to defaults. Apparently won't have any noticeable affect on speed?

You're most welcome.

There's little to no impact on throughput (speed) as long as the equipment is working properly.

dhcp is allowing both devices to determine the address to use automatically, instead of you having to program it manually

for surfing the web, email, youtube, it doesn't much matter what address your device has, or how many hops it has to get through. your setup is what's called double NAT - network address translation. The modem is taking the ISP provided address and translating it into a range of addresses (192.168.x.x in the example above). The router takes one of those addresses and then does another translation into a new range (10.10.x.x for example).

this only becomes a problem if you're trying to setup outside access to something, or apps that are very sensitive to timing (twitchy shooters)

OK, will do. But just as an additional morsel of info, if I unplug the CAT5 cable from the router WAN port, and connect the modem directly to my laptop, the laptop accesses the web just fine. If the modem generated 10.10.x.x, would that still work? I don't know about this stuff... just trying to learn a little.

My home setup has a router at the WISP antenna and I have my own as well. It works fine that way. The antenna DCHP generates 10.10.x.x addresses and my internal router generates 192.168.x.x for the devices in my house.

x2, leave DHCP turned on, for both devices.

Simply trying to streamline the system, but using whatever protocol is correct. The Netgear modem is set to be a router (DHCP on), and it is feeding another ROUTER, which needs to have DHCP on. I thought that might create a conflict. Maybe not.

Yew, DHCP. Senior moment 🙂
