Just bought a new Motorola SBG900 wireless modem, but I using it as wired-ethernet hookup (which I was told by Best Buys, that this should work fine, because it has an ethernet port). I have the modem up running and a Linksys router-on the internet and doing fine, but when I plug the Linksys PAP2T, the phone ports do not light up and I have no dial tone/service. I was fine with the old modem. I have spoke with Motorola and Linksys (without much response. Any suggestions about what the potential problem is?????
Thank you,

Not sure on your setup there, But if you have DSL or cable modem which device is hooked to it? If you are doing the daisy chain effect make sure it is as follows.

Like here i have two WRTP54G routers.

1st one is pluged into the cable modem via the wan port, the ip on that unit is 192.168.15.1 with DHCP turned on, Then one of the 4 ports off there runs to the second linksys router into the wan port where i had to set that ip as 192.168.16.1 DHCP is off.

Doing the daisy chain effect you have to increase the IP by 1 or there is a conflict.

hope this helps!!!!

I would check to make sure that your new router has uPnP turned on. It's what is needed to make sure that the port forwarding is setup right.

No it's not! And IMHO uPnP is a BIG security problem (as it essentially lets ANYTHING (including viruses your computer may be infected with) on your LAN open up ANY PORT it chooses to...

Now, uPnP might make it easier to configure the router's "firewall" (port forwarding, etc), but it's not needed. Pretty much any router these days will let you setup proper port forwarding if you want. So uPnP may be nice from an "plug and play" standpoint. However, if you pay attention to what is being blocked by your router, pretty much any router will let you unblock those ports "manually".
