I tried Networking, now I'm trying here

[JeffreyLebowski]

I just got Cable modem throu AT&T and I want to set it up through my d-link 4-port router/switch

I followed d-links instructions and it still won't work. I've been jacking around with this for 3 hrs now and I'm still in the starting blocks. I've had to stop myself from taking that piece of crap out back and blowing it to hell.

Somebody please help me.

So I assume you have plugged the ethernet connection from the cable modem back into you PC right? I've nevered used a D-Link router but all of the SOHO routers are close enough.

Did you spoof the MAC address? Of if the option is unavailable, call AT&T with the "I just got a new PC" story and give them the MAC address of the D-Link router? Did you setup the DHCP server in the router?

Power down the cable modem and router.
Restart the modem, then restart the router.

The routers MAC should then be seen only by the cable company PROVIDED they are using DHCP.
If they are assigning IP ( I know most all don't , but there are some exceptions ) the router can't pick up an IP you have to assign it yourself.

Still having problems?
Check to see if each pc on your lan has been given an IP from the router. Most will do the 192.168.0.xxx IP range for Intranets.
If the pc's don't have an IP then the router is faulty.

Make sure your network cables are the same at both ends, not crossover... mine was, it sux0rsed took me ages to get it going...

I've cloned the MAC address onto the router. when I check the ip of the machine it comes up as 23.2xx.xxx.x which is a ATTBI address. I do have the computer set to obtain an IP addy, and the router set to DCHP server. Maybe I need to change out the cat5 cable att gave me with the modem. maybe it's wired different or something. cause I can get it to connect if I plug the modem straight into the computer with a cable that I made.

It's just so frustrating, why cable and DSL companies make it so hard to share out an internet connection. If they are going to offer my X-amount of bandwidth, I should be able to use it however I see fit.

try different cables - at&t may have given you a crossover.....

I had a Cable modem for a while from AT&T @Home and they had given me a specific IP address. It never changed. There was also a proxy address for the proxy server. I guess you should have like printed out all this info from your system tools menu before you started. I would have bought Linksys equipment. I have a Full Duplex Linksys Wrokgroup switch and I like it a lot. I wouldnt try to uplink to the the cable router, I would replace whatever you have with the cable router if possible. With an uplink port from what you have to the router, you wouldnt need a crossover cable. An uplink port does that for you.

I would have thought plug the router to the cable modem and plug one of the ports into your computers network card or to another swithch or hub that all the computers are already on.

thed-link worked flawlessly with my DSL. I would have printed out the info, but there's one problem with that. I don't own a printer.

Yup - the cable that AT&T gives you is a crossover. You need straight-through.

If it's not the cable, just call D-Link's # on the installation manual.. it's not toll free, but when you call, they give you a toll free number (can't remember it off hand). I called, and they had my problems fixed in 3 minutes (Adelphia cable = evil).

I'll try that when I get home.

Also, it sounds stupid, but check how many clients the router's dhcp client is good for. If it's under the amount of PCs you are running it just won't assign them addresses. I had a Linksys router that came with 0 enabled as default, so just enter the number of comps you plan to be running on the router, or even a few more to avoid future headaches.
