Autoconfiguraiton is enabled on network card

I am trying to connect a comcast modem cable to my pc. The comcast equipment is working but it can't get the ip #'s from comcast because of the 'autoconnection.' is enabled.
I've tried to disable it by using 'ipconfig/release' but I get the following message: All adapters bound to dhcp do not have dhcp addresses. the addresses were automatically configured and can not be released.
I've also updated the network drivers, replace the network card with a different brand. Uninstalled & reinstalled the network card. Nothing is working.
I have a Dell Windows2000 Pro Pc.

Please help...:--D

 

Do you have a router? No? Consider getting one.

If you had a comcast technician install your service, he/she should have made sure that you had a connection to the Internet before leaving the premises. Among other things, the technician would have made sure that your modem was provisioned.

Did that happen?

Answer that question please.

Is is unclear what you mean by 'autoconnection'.

Once you have a connection to the modem, after the modem has been provisioned, the modem stores your MAC address in its ARP cache. If you change the interface that talks to the modem, no communication will occur. To clear the ARP cache on the modem, power down the modem completely (unplug it) and wait a good long while. Go get coffee. And plug it back in. The first device plugged into the modem will give its MAC address to the modem ARP cache. From that point forward, this will be the only device the modem will talk to until you do the power cycle trick again.

If you were not there when the technician ensured that the modem was provisioned and the technician used HIS laptop to ensure a connection to the Internet, then it is possible that the MAC address from the technician's laptop is what is currently in the modem ARP cache--preventing you from getting a connection.

There's nothing that cannot be released.

See ARP cache above.

 

The modem is working properly. The tech left b/c he was at a lost. Comcast tech support says that I need to turn off the 'autoconfiguration'. Comcast can see the modem on their side.
Still need help.
:--D

 

when you type ipconfig/all you get the following info:
dhcp enabled.... yes
physical address...00-a0-....
autoconfiguration enabled .... yes
autoconfiguration ip address.... ###.###.###.###
default gateway....

this is where that autoconfiguration is showing.

I tried to type ipconfig/release but get the message in my 1st message above. All adapters bound to dhcp do not have dhcp addresses.All adapters bound to dhcp do not have dhcp addresses.

This is a non-sequitor. What is the indication that the modem is working correctly. If you can't connect to the Internet with a single system and no router, then the Comcast Tech should have stayed on-site until it was working. This is the minimum that they guarantee. If you introduce a router, they won't guarantee operation (even if that is a better way to operate, and OTOH, it usually works flawlessly.) However, you have one system directly connected to the modem. The tech being at a "loss" and leaving is lame. There could be more than one thing contributing to your problem.

Them being able to "see" it is bogus. I've had Comcast tell me that for weeks until I finally got them to send a technician out who discovered the wrong filters installed up on the pole. If the technician could not get his laptop to connect through the modem, they didn't confirm a good install.

In talking to them on the phone, they should have, at least, given you the same instructions about clearing the ARP cache on the modem as you got from me, here. They also should be able to talk you through setting up your network properties until you achieve success. If not, then they need to dispatch another tech to do the job right.

What did your do for an Internet connection before Comcast? If it was DSL PPPoE, then the Comcast tech probably doesn't know what to do. If that is the case. then you must remove all the software from your previous ISP that implements PPPoE. This may be one uninstall or more than one depending on how PPPoE or WinPOET was implemented. You can't run PPPoE unless you have something on the other end that understands the protocol. After that, reconfigure your network properties.

Go to local area connection properties - TCP/IP properties --
and click on Obtain an IP address automatically. Click on Obtain DNS server address automatically. Click on the advanced button. The IP settings should say DHCP enabled. Click on the DNS tab. Uncheck the "Register this connection's addresses in DNS." Click OK. Click OK. Where your adapter is listed in Local Area Connection Properties, click on the Configure button. Does it say the device is working properly? Click on resources tab. Does it say "No conflicts "? Click on the power management tab and uncheck both boxes if either is checked.

Next time you talk to Comcast, ask them what they mean by "autoconfiguration" -- ask them, because they know that is the problem, to walk you through making it not so.

If they mean APIPA by "autoconfiguration ", you only get an APIPA address when your DHCP request is ignored by the Comcast DHCP server. That will only happen when you don't have a good connection. This would mean that Comcast hasn't delivered the connection that they say they "see. "

APIPA - Automatic Private IP Addressing; you don't turn this on or off--it works as a fail-over. From Webopedia -- With APIPA, DHCP clients can automatically self-configure an IP address and subnet mask when a DHCP server isn't available. When a DHCP client boots up, it first looks for a DHCP server in order to obtain an IP address and subnet mask. If the client is unable to find the information, it uses APIPA to automatically configure itself with an IP address from a range that has been reserved especially for Microsoft. The IP address range is 169.254.0.1 through 169.254.255.254. The client also configures itself with a default class B subnet mask of 255.255.0.0. A client uses the self-configured IP address until a DHCP server becomes available.

Comcast telling you that the problem is autoconfiguration is bogus. If the next person you speak to on the telephone at Comcast tells you this, and they can't tell you something new and different than you see here then read them this message, and ask to somebody who really knows how to troubleshoot your connection problem.

If they do tell you something new and different, please follow up here so I can learn something.

They don't have DHCP addresses because
they couldn't find a DHCP server --
Comcast's DHCP server.

Either the Comcast connection is bad
or the modem is bad
or their provisioning of the modem is bad
or the ARP cache isn't cleared
or your cable is bad
or your NIC is bad
or your network configuration is bad.

Regardless, Comcast should fix the problem
unless it is a bad NIC. It doesn't sound like
a bad NIC.

 

is there a way I can send you a picture of the ipconfig/all window showing the 'autoconfiguration'. Maybe seeing it will help understand what i'm seeing and trying to explain.?

 

The nic card is working properly. I've changed nic card and the new one is giving the same information.

the time the tech was out he didn't have a laptop.
Called comcast and they can send another tech out but will cost me $45.00. If the tech can't solve the problem I will still be charged the $45 for the service. I told her, charge for service, what service is it if he can't resolve the issue.

I'm looking at my work Pc and the ipconfig/all shows noting labeled 'autoconfiguration'.

Please adivse.
Thanks.

w.young - no need to try to send a picture since you are using 2000. Just as well since the forum won't allow them.

start~run~cmd
ipconfig /all > c:\config.txt (you won't see any results on screen)
Open c:\config.txt, copy the contents, paste it in a post here.

And please don't mask anything. You may well be covering up the bit of data someone needs to solve your problem. For instance, if your IP is an APIPA like Bitbyter wrote about, it is essential to know that. But no way to tell without seeing the address.

As a side note and I'm assuming here that comcast is your ISP - if comcast has never gotten you connected properly then my feeling is they owe you an aplolgy rather than charging you for troubleshooting an issue that's been there since the get-go.

 

All Newt's comments are spot on. Responses to his questions would be valuable to the troubleshooting process here.

 

I will make a copy of the ipconfig info tonight and post it tonight.
