And then my router isn't able to connect to the internet. I use DHCP and went through the routers wizard to connect the router to the internet after bridging the modem and it isn't working.
The modem is on 192.168.0.1/24 and the router and computers are on 192.168.1./24. Do I have to leave the modem and router running to get a new DHCP lease, because I did it yesterday and it isn't working today when I turned them back on.
I looked on the modem and didn't see any setting to release the IP before I bridged it.
Do I have to clone the modems MAC address on the router?
My CL DSL account is not PPPoE as I never needed to enter a phone number or password when using just my zyxel 660 modem without a wireless router. When I then connected the 660 to my wireless router, I simply set the modem to bridge mode and I had no issues and never dealt with any kind of password for PPPoE. If the OP does not have a PPPoE type of account there won't any kind of password involved. The only thing that really came into play with my setup related to the wireless router initially having the same IP as the modem so I had to change the IP for the wireless router in order for bridge mode to work.
Yeah I upgraded to the N66U from the Linksys WRT54G and have been happy with it. They add new features in the firmware every once in a while like the ability to tether a 3g phone/device to it so all your computers can use 3g as a backup if the internet goes down.
