Weird home network issue

Recently, my mom signed up for dsl to save a few bucks off cable, but it's too slow so we're

switching back to cable. The only problem is the network here isn't working anymore. I've

narrowed it down a little bit though. This is the setup btw: cable modem > router >powerline

> switch > mac + xbox. When I connect the cable modem directly to the powerline and then

to my laptop or even just directly to my laptop it works fine, so the powerline isn't the issue.

If I try to plug my powerline into my mac, however, it doesn't work at all, it says "self

assigned ip". If I add the router between the modem and powerline to go cable modem >

router > powerline > any device, nothing works either. I can see the network being

broadcasted by the router, but it's local only when I connect to it.



I have no idea why the mac can't connect when it's basically directly to the modem and why the router isn't routing any internet at all. I've already tried resetting and restarting all the devices on the network so that's not it either. Maybe the router's broke? I dunno.... Any help is really appreciated, thanks!
 
is the modem in bridge mode with DHCP disabled as well as NAT? if you are going from modem to router it should be configured that way and let the router handle DHCP and NAT.

How would I be able to tell if it was in bridge mode?
 
well that i couldn't tell you exactly, but usually the configuration for the modem will tell you if its in bridge mode somehwere. I can't even tell you how to set it really cause i have never had to LOL. I'm sure some of the pro's around here will be able to help you out more than i can, it just sounded to me like you don't have the modem bridging right.

If it gives a DHCP address, generally, a 192-type address, its not in bridge mode.

If it gives you an external IP, IE, the same as what ipchicken.com reports, its giving you straight out external, no DHCP/NAT.

If it gives you no IP, and your PC reports a 169, its prob in bridge mode, and you need to call the ISP to add the mac of the router.

I'd also check to make sure there are no leases assigned by anything that hands out any IP address, and, I would make sure nothing has an assigned IP address.

What is the gateway/DHCP server? Nothing else is capable or configured as such?
 
thanks for the info scotty, as tomorrow i get in a new router and will have to do exactly this.
