Unable to renew IP address

I have a gateway pc running Windows XP, and about a week ago my internet stopped working on it. I would open up internet explorer and it would say something like not having an ISP and gave me the option to work offline. I've tried to repair my network connection only for it to come back with an error "unable to renew IP address"

i've looked at microsoft's website on the computer that i'm on now, my laptop, and a site i went to said it may have been a Winsoc32 key corruption; so I downloaded and used the guided help from microsoft and it showed there wasn't a corrupted key.

Also it's not like a lot of other problems i've seen on this site where the network connections balloon pops up and notifies of a "limited or no connectivity", mine says the device is working properly but it's not performing! Any help would be greatly appreciated!

how are you connecting to your network? is it wireless or cabled?

what ip address do you have at the moment?(open up a command prompt and type in ipconfig) and press enter... let me knw the result

cabled (6mb cable broadband from comcast)
192.168.0.1

Fist of all, what type of cable-modem do you have? (Motorola, Ambit, etc)

The cable modem should have a LAN link light which should go on or off, depending if your PC is connected or not. Does it work that way? Also, the cable modem should have a 'Sync' light, which should be on and steady.

You should not have to set a static IP address in your PC, your PC can get that device from the cable modem and/or ISP.

When you go to a command prompt and type 'ipconfig /all', what is the result?

you should see a default gateway address of something like 192.168.0.1. You should be able to ping it by typing ping 192.168.0.1.

Do you have personal fireall software installed?

i see the problem......... if your ip address is set to 192.168.0.1 then that will be conflicting with your modem router having the same ip.....

if your router/modem is 192.168.0.1 , change your ip to 192.168.0.2

your computer has to have the same 3 sets of numbers as your modem/router but the last 1 has to be unique

im not using a router... the connection goes right from the cable receiver to my computer.

sorry, i'm not technically gifted... how do i change my ip address?

by xvnight

Also I just noticed that when I look at the ipconfig there isn't a Default Gateway address.

by shady108

open up a command prompt and type

ipconfig /all

ive read a fw posts on other forums other people are having the same issues with u with comcast

the other thing that has been suggested is unplug your cable receiever from the power for 10 mins. turn off your pc. turn on the cable receiver until all lights are on and then powe rup your pc

I'm pretty sure it's not a comcast problem because I plugged the ethernet cord from my gateway pc to this dell laptop and the internet fired right up, no problem.

by ic-it

(and Shady is right). The cable modem needs a complete reset. It has basically grabbed the MAC of the Dell and wont release it to get the Gateway's MAC.
After you power off the cable modem, also unscrew the cable connection. Wait 30 seconds and connect it to the Gateway. Power it up and then screw the cable back on. Power off one more time and then restart everything.

have you got any internet security software or firewalls running on the pc?

can you go into your tcpip settings of the network adapter and list what you have in-

ip
subnet
gateway
dns

by xvnight

ip: 192.168.0.1
subnet: 255.255.255.0
gateway: (blank)
dns: (blank)

First, resetting the cable modem is the first step. The first computer to access it will be the one that will 'work' properly. Others will fail unless you reset it. I recommend picking up a router to use multiple systems on your home network.

If that fails, try these.

I have been running into a recurring problem recently where XP just stops working with the network properly.
open control panel, go to administrative tools, device manager, uninstall your network card.
after it finishes, then scan for devices. It just may start working afterwards.

If not, go to start -- run -- type (without quotes)
"netsh int ip reset resetlog.txt"
press enter.

Then check the status (after a minute) by
start -- run -- type "cmd"
in the dos window type "ipconfig /all"
does it now have a gateway, DNS, ip address?

by xvnight

thank you! Im on the gateway now, I hit reset and typed the ip reset and when all the lights on the cable box came back on I checked my ipconfig and it was normal again! Internets working golden.

thanks again!

by xvnight

I have an Arris cable modem.

theres no default gateway but i can ping 192.168.0.1 no problem, but if i try to ping microsoft.com or comcast.net it comes back with an error.
no firewall software on the computer

do you want me to tell you all the info the ipconfig /all shows?
