2:13 pmThere are some good reasons to have a modem bridge rather than route. I can't speak for all modems, but generally speaking:
1. Modems don't have much memory compared to a good router, so open a few sessions from the LAN and watch as connections get dropped, or worse, the modem/router just locks.
2. Modems tend to lack features compared to a good router. Things like QoS, DHCP reservation, VPN, uPNP, static routes, etc get left out. You can provide your own router behind the modem, as you did, but this can lead to other complications, such as
3. Double NAT. Most things can be made to work with double NAT, just as it's entirely possible to assemble a jigsaw puzzle while wearing oven mitts. It takes longer and the probability of making a mistake while setting it up or troubleshooting goes up. Simplicity is a good rule to live by when setting up networks.
#2 Advice
a) Make sure that all of your computers are behind your RJ-45 WAN port (what ever that may be) router.
b) Important note: The RJ-45 WAN port router's WAN port must be connected to the LAN (or one of the LAN ports) of the Modem combo.
c) and put the modem combo into bridge mode. As how to get the modem combo into bridge mode, you may need to contact your ISP and get help from them...
