hello everyone, my friend is having a computer problem so i am looking for help.

problem behind cut



ok she just got cable modem with comcast. she has a ultra something modem i think. her mom bought a d-link 4 port 10/100 router and 2 d-link 530x ethernet cards. i installed the ethernet cards and the router and hooked them all up. i called tech support and the person said that you have to connect one computer up directly to the modem before you can set it up for a network. now when i had the computers hooked up to the router, they are using the ip address 192.168.0.100 and so and both computers can see each other and i can access the webshell to set up the router. when i hook up a computer to the modem directly, it gives the computer it gives which ever computer it is hooked up to the ip address of 169.###...... i called tech support and they said that it has to be a 192 or 120 or something ip address in order to work. i tried assigning an ip of 192.168.0.100 myself but that didnt work either. one computer is running windows xp and the other is runing windows 98. also, i tried using the built in ethernet card on the computer that is running xp and that did not work either. and also when i tried to renew the ip address while it was connected to the router it would renew it to 192.168 and such but while it was connected to the modem it would either not be able to renew the ip address or it would renew it back to 169. also i tried unpluging the ac adapter from the modem, unplugging the coxialal cable for 5 to 10 seconds and then pluging it back in, then putting the ac adapter back in and resetting the computer and that would not work either. i even used my own laptop that works perfectly fine on my home network and dsl connection and it was given an ip address of 169..... when connected to the modem and would work with the router. and when i tried the setup on the cd that came with the modem it would get to the point where you renew the ip address and it would say that it could not do it. also i could not run the normal setup program that came with the modem on either of thier two computers because it said it needed 128 mb of ram, but they have 64 or 96. i was able to run it on my laptop and i said what happened already above ^_^. but when i called tech support, he said that there was a way around this, going to sas.r5.attbi.com. i tried this on each computer and it said "windows could not open the search engine." i also tried setting the automatic connection script and proxy to sas.r5.attbi.com and *r5.attbi.com or something like that like he said. no matter what, when a computer was directly connected to the modem it had an ip of 169 something. i even tried to connect to sas.r5.attbi.com through the router, because when the router is connected to the computers, they have normal ip addresses like 192.168.0.100 and 101. but that didnt work either. they have comcast cable. um...what else is there to say...the cards obviously work because they can see each other on the router. for some reason the modem is giving them bad ip addresses. and connecting to the intereted through the router to the hub doesnt work either. um. the ethernet cards drivers were from like 3-03 so i think that maybe if i find new drivers it might work. so i was over there from like 3:30 to 12 trying to get this to work,

please help

Sorry, can't help you right at the moment... not conscious enough to read through your post.

Two pieces of advice, though:
1) For the love of god, learn to use paragraphs.
2) Ask in tech_support. :)

If you get an ip of 169.* when the computer is connected directly to the modem, something's fecked up. If everything was working, you'd get a valid address, and not a 192.*. Do this:

1. Reset the modem (unplug the power for 10s, plug it back in)
2. Reboot the computer
3. Check the cabling
4. Reinstall NIC drivers

That's pretty much what they'll tell you to do, if I remember correctly. They've probably changed their process since I last heard from them.

(Please use paragraphs, it's really hard to read a block of text like that.)

It sounds like your modem doesn't have connectivity. If you are getting a 169 IP address when connecting one computer directly to the modem, then you are not getting a valid IP address. I have a few questions for you:

1: What brand of modem is it?
2: What are the lights on the modem doing?
3a: Is the modem connected to the computer via ethernet or USB?
3b: If you are connecting via USB, have you installed the modem drivers? (Make sure you are only using EITHER ethernet OR USB and not trying to use both at the same time.)
4: When you unplugged the modem did you unplug it for at least 30 seconds?
5: Do you get the 169.x.x.x IP address regardless of which computer you connect the modem directly to?

Also, a piece of advice for you: Unless you can get a valid IP address when the modem is connected directly to the computer, trying to set up your network is rather futile. Connect the modem directly to the computer and call Comcast support and tell them you need help getting registered and that you aren't getting a valid IP address. They will be able to run some tests to see if your modem is even connecting to the network at all. They can use your modem's MAC address to find the modem's IP address and they can try pinging the modem from their end. If that fails, they'll need to have a technician come out... Assuming you don't just have a loose coax connection somewhere or a splitter that isn't rated for cable Internet.

1) not sure right off top of head what kind of modem it is

2) 4 of the 5 lights were continously green. the only one that isnt is the activity light which is flashing yellow

3) not connecting through usb

4) yes

and i called comcast and they did run a test and they said that a 169 ip isnt valid and that they werent getting a signal from the computer

[gaymafiakingpin.livejournal.com]

The modem will have an IP address of it's own. To determine if the problem is with the computer or with the modem (or otherwise) they will need to attempt to ping the modem, not the computer. If the computer isn't getting a valid IP address there's no need to bother trying to ping the computer. That 169.254.x.x IP address already indicates that the computer isn't connecting. If they can successfully ping the modem, then it will be more likely that the problem is with the computer. If they can't even ping the modem then they will need to send a technician out.

Sounds like a Surfboard modem.
Solid Power, Receive, Send, Online - bliking Activity? That sound right?

If that's the light pattern, your modem is locked. If you cant get an IP, it's likely the PC at fault. To make SURE the PC is the problem, tho, try to get a diagnostic IP from the modem like this:

- Unscrew the coax (cable line)
- Powercycle the modem (unplug, wait 10sec, plug in)
- DO NOT plug back in the cable line yet.
- Reboot the computer
- Check IP.

If the IP remains 169, then the problem lies in the PC config OR a bad NIC, OR a bad ethernet cable, OR a bad ethernet port on the modem.

Check the back of the modem where the ethernet cable plugs in. (Check this when the PC is turned on.) Any lights? What colors and are they blinking or solid?

[teriwyn.livejournal.com]

Actually, I just suffered thru reading your post, and what I gather is this:

- The PC gains a 192.x.x.x IP from the router
- The PC gains no IP (169.x.x.x is used by Windows in the absense of a DHCP IP) from the cable modem.

Simple question... when you tried to go from using cable modem to using one PC connected directly, did you powercycle the modem? Is this a Comcast area that used to be ATTBI or was it always Comcast? (The network is set up differently in different areas.)

If it used to be ATTBI, let them know that your originally connected a device with one MAC address (being your router), and you are trying now to hook up a device with a different MAC address (being your computer).

If it is an area that was always Comcast, then the above step is not necessary and all you have to do is powercycle the modem.

[tjernobyl.livejournal.com]

When I worked for ATTBI in the spring, the authentication was entirely based on modem MAC. Though the system recorded all the MACs it saw past the modem, it allowed them all access so long as the modem MAC was authorized.

[teriwyn.livejournal.com]

I understand that changes have recently been made to SAS which prevents more than one CPE MAC from obtaining an IP unless additional IPs are paid for. Thus, limiting the number of IPs able to be used concurrently to one. In order to switch the registered CPE MAC, the user typically needs to go back to the SAS page from the device that originally obtained the IP and release ownership. (Using lay terms because I'm not sure what jargon is actually in use, now.)

Since I do not know if the router really ever obtained an IP or not, it's hard to say if there's anything in SAS at all, binding the router MAC and preventing a direct connect. If the router DID, but they couldn't get it working the first time, then connecting from the orignally used CPE will be impossible and an agent will likely need to release the last-used MAC. Further, if they're in a classic Comcast area, we don't use SAS at all and the point is moot, heh.

Just trying to account for all possibilities.

the link light on the back of the modem is solid green and the activity light is blinking orange

when i had the coaxal cable out and rebooting the computer, it has an ip address of 192 soemthing, when i pluged the coaxal cable back in and on the computer hit renew, went back to the 169 ip

You don't know how to use the enter key!

i do so

it was just 2 am and i was realy really tired from lack of sleep and stressed because of this and i was practically falling asleep in my chiar

sounds like your using a DOCSIS modem.and that way you cable company has it setup is to have the modem lock in the MAC address of what ever device plugged into it.so this is how you can fix it.hook your router to the cable modem.then hook you computers to the router then call your cable company's tech support tell them you changed computers and that you need for them to release the MAC address from the modem.if they are about to do this then the cable should let you use your router on it.if they can't.then this is what you can do this modem will relearn info.before you go to sleep plug-in the router to the cable modem and leave it connected over night also be the router is set to a direct connection not pppoe.and the next morning the cable modem should relearn the new MAC and you will be about to browse.i would also remove any static IP's you may have added to the NIC cards.

Sorry about the way my directions came out I was typing them as i was working on something else.
