Computer can't aquire ip address

If you have the model number we can assist you. There are several things that you need to know. Your password to the modem if you have changed it, You need to be able to connect directly to it with a network cable,

Disconnect the coaxial cable from the Arris.
Turn the Arris off.
Connect an Ethernet cable from your computer to the Arris.
Turn the Arris on.
Turn on (or reboot) your computer.
Open a command-line prompt on your computer.
Enter 'IPCONFIG' to see the IP-address of the "default gateway".
Open your web-browser, and type that IP-address into your web-browser, to access the configuration-page of the Arris.
Configure the Arris.
Turn the Arris off.
Connect the coaxial cable.
Turn the Arris on.
Reboot your computer.
Done.

Try 192.168.0.1 or 192.168.100.1. Make sure that your pc is connected directly to the Arris TM602G modem and not on a router.

comcast use 10.0.0.1 for ip address, I think
check direct tv box for internet settings for it's ip address should 10.0.0.2 maybe call directv maybe they could further.

Your ISP should have given you the following information...
Static IP, Internet IP Address, Subnet Mask, Gateway, Static DNS 1-3.
With that information at hand, follow tis link to the router user manual and go to Page 11 of the manual to go through the step by step process of setting the router up for an internet connection.

I just installed a Belkin N1 (model F5D8635-4 v1000) to a Comcast Arris modem in SW Florida by resetting the IP on the router to 192.168.1.1 Comcast assigns 198.168.0.1 (but will accept 192.168.1.1 however not .2.1) and Belkin default is 192.168.2.1. Problem is easy enough to correct by following the instructions for changing the default router IP using a Firefox interface as documented in the user's manual. Note that when applying changes it takes about 30 seconds for changes to be effective.

This would normally mean that you have assigned the IP address manually but have also given that same IP to another computer and they are fighting about it.

If this is the case then just check your IP allocations and find out which computer is using the same IP and change it to one that is not in use.

It may also mean that your router is trying to use the same IP as your modem

With just your modem connected to the computer

go to the START MENU / RUN then type CMD and press enter.

Now in the black screen type IPCONFIG /ALL

Take note of the numbers esp in the default gateway, that is your modem)

Now with just the router connected by wire do the same thing.

This time the default gateway is your router if it is the same as your modem then you need to alter it in your router,

You haven't given a model so you will have to work this bit out yourself but your are looking for a setting on your router that starts with the same number you got.
If your default router gateway was lets say 192.168.1.1 then that is what you would be looking for. Change the third block so now it reads 192.168.2.1 and save the settings. This would clear any conflict between modem and router.

If you have assigned IP's to computers they would need to be changed to reflect the routers new IP and again you would just change the third block in the allocated IP to a 2

If in doubt read this a couple of times or print it out.

This could be a duplex issue. When you log into the belkin does is assign you an IP address? Have you used a ballpoint pen to reset the EMTA since you have connected the router?

That's Ok.

Is your computer connected directly to the cable modem from comcast and what type of connection if it is?(USB or Ethernet/LAN-its look like a telephone chord for slightly larger) or are you using a router?

First thing that you need to check is the actual modem(box provided by comcast normally the brands are; arris, motorola, webstar, samsung or linksys. Make sure the LED light on the front of the modem that say's either Online/Ready/Cable/nternet is stable or solidly lit.

Go to Control Panel and look for Network and Internet or Network and Sharing Center, on the top left hand side you will find tasks, look for manage network connection and check if you have a local area connection, right click the icon and go to Status then Details. Check if you have an IPv4 IP address(58.x.x.x or 271.x.x.x or something like that) if the IPv4 show as 169.254.x.x(where x can be number s from 0 to 254) its an invalid IP or your computer is not getting any valid IP from Comcast.

you can find your I.P adress on the PC you use at home that is connected to the wireless modem.

if not theres an option on the xbox 360 to find the I.P automaticly try that!

hope this helps please rate me
