Cable internet IP problem; shows 192.168.1.1

November 26, 2010 at 15:18:02
Specs: Windows XP
I am using cable internet. My lan provider is most probably using routers. They change DHCP Server IP needed for the internet service to connect from time to time. For e.g. it's currently 10.127.8.1

But sometimes ipconfig/all on my PC shows DHCP Server IP as 192.168.1.1 and then the internet doesn't connect. But the local area connection shows 100Mbps.

Is it the problem with my motherboard slots? my lan card? or is the problem on the side of the lan administrator?

I have checked different lan cards but can't come to a conclusion. Some work & some don't.

I require help please.

Thanks in advance!

"My lan provider" ??

Who is your LAN provider? Shouldn't you be asking them?

lan provider means the admin. basically the person who manages the network. he keeps saying that there is no problem on his end. it might be a lan card or cable fault. but he is not a technically sound person. he might have hired people when he was setting up this business then he started running it on his own.

Only the wan port of the router has 10.127.8.1

It is normal that you get a ip address in the 192.168.1.x ip range for a lan.

These have nothing to do with you not having internet access.

Post the results of an ipconfig /all for review from your workstation.

Unfortunately, you have to depend on him. It doesn't matter which internal block is used. 192.168.1.X is fine. Try ipconfig /release & ipconfig /renew. I don't know what else you can do if the "admin" is not qualified.

when it works okay, it gives the dhcp ip 10.127.8.1. but when there is something wrong, it gives dhcp ip 192.168.1.1

the admin who is running the network in our locality has a lot of computers connected thru different routers. he keeps saying that its the fault of my cable or my lan card that i'm getting a 192.168.1.1 ip.

Ethernet adapter Local Area Connection 9: ????????

Why are there 9 LAN connections on your PC?

No. It's only a single connection. I have 4 PCI slots so I was just checking my lan card on each.

phenomfawaz it does not appear you have a router but are connected directly to the modem.

Either that or you have the cable from the modem cabled to a lan port on the router not the wan port of the router.

Correct your configuration so you are connected to the router

modem<>router<>pc

How do I do that? I only have a PC with a lan card. the rest (modem and/or router) is not my property.

Hardware does not decide what ip address it gets unless its been burned into it for some reason. You eliminated that thought with replacing the nic cards as tests.

If you are just connected by a cable to an outlet or port in the modem, then two things:

1. you need to buy and put in a router of your own.

2. if you got a 192.168.x.x ip via the cable company then that is a messup of theirs

Now there are settings in the Alternative Tab under the nics properties that allows you to put in a static ip address if dhcp fails. Might want to check if your nic has this setting. Some don't.

The only other way I can think you could get that address is if you had wifi and connected to a wifi router that was giving out that ip. Though usually 192.168.1.1 is that of the gateway.

I am kind of confused here. Firstly, if everyone in my locality doesn't have any problem, then why should i buy a router? I have been using this cable net for about 2 years from the same provider. It's just now that the problem has occurred. It is obvious that there is some problem, i just want to know where it is.

The company who provides the internet services have sold their dealership to lan providers in different areas of the city. There is a dialer that requires an id and a password. i have them. the dialer only connects if the condition that i've stated in my previous post fulfills(mentioned above in my "ipconfig /all" result).

What does people around you have to do with your cable access? They each have their own line right?

The suggestion to buy a router is one of the steps in how you protect yourself on the internet.

Your issue, as you describe it, is you get a private ip address 192.168.1.1 and when you do internet doesn't work.

There is NOTHING you can do since this is NOT a problem with your pc. It's a problem with the internet provider.

What would be very helpful in documenting this is to have the results of an ipconfig /all show the 192.x.x.x ip. That is what I would like to see.

Good job phenomfawaz. I see what is going on now.

Looks to me that you have a rouge or misconfigured dhcp server on your lan.
Notice how this ipconfig is missing connect.net.pk?

Who is in charge of the network where you are?
How many people in your office?
If you put 192.168.1.1 what comes up? Should be the routers logon page. Say what brand of router?

The others that work are they in the 10.x.x.x ip range also?

Thanks. Yes I notice that.

It is not my office network. I'm using it at home. The person I have mentioned before is in charge.

The problem occurred again yesterday. But it was only for a short period. That's how I was able to send the above "ipconfig /all" result.

When the problem occurred, I tried pinging at 192.168.1.1 and it gave a normal reply of <1ms. But I didn't try it in my browser, and I don't know how to.

And yes I believe that they are in the same IP range.

just put 192.168.1.1 in the address line and hit go.

I would suggest talking to the person in charge and explain what you are experiencing. Only this person can change this.
