Can Internet connection sharing be reversed?

Hello everyone, I just joined the forum looking for questions about my wireless network that I have been trying to set up.

I have a XP computer that has a cable modem. I was setting up a Netgear wireless router so that my son could connect his new Vista computer to the internet. Went through the Netgear setup wizard and things were going ok until I could no longer access the internet from the main pc to complete the wizard. The network has been created, security enabled, and able to be connected to by the new pc, but it is not able to connect to the internet either. In trying to complete the setup, and get back the internet connection on the original pc, I ran the network setup wizard in XP thinking that was a step I was missing, but now I think that I may have enabled Internet Connection Sharing without really knowing what it was. When I run ipconfig /all on each pc, I get an IP of 172.16.0.2 on the XP and 172.16.0.3 on the vista. Dhcp and dns show same number only ending in 1. Does anyone know of a way to reverse Internet Connection Sharing? I have thought about doing a system restore, but not sure if that would help.



Thanks for any help with this

Welcome to the forums!!



This is what I would do (test after each thing):



1. Power cycle the modem and router. Discount both, power up the modem first, then (after a couple of minutes) power up the router.



2. Confirm that all of the modem and router connections are correct. The cable coming from the the modem should be connected to the WAN/internet side(port) of the router and the PCs into the other side. Make sure all connections are tight.



3. Run the Network Setup Wizard again on the XP PC. This will overwrite any previous incorrect settings.(I would not worry about the Vista machine until I got the orignal PC working)



4. Run the Set Up Wizard for the router again.



If you get that far with no luck, let us know and we can try some different things.

just compleatly reset the wireless. hold the reset button on the back for 30 sec. That will return it to default settings. Then i would sudgest setting it up yourself by going to the main web page. 192.168.1.1 user (if i rembore correctly) leave it blank or try admin password is, password and set it up manualy.

Ax: I have tried all four steps you mentioned, all with no luck.



Brian: Question before doing this, If I try to set it up manually, what settings should I use for the IP address? When I first went through the router setup wizard it stated that it determined that I had a static IP address, but rr tech support says it is dynamic? What should I choose, and what are all the steps I would need to take?



Thanks for the help guys,

Scott

it should find your internet automadicaly. all you do is conect the router to your computer via the lan cord. dont connect it to the internet. Hole the reset button and it will reset itself it will give your computer a ip of 192.168.1.2 type in the address in internet explorer 192.168.1.1 there it will ask you what servace you have, just chose auto which it will find the ip. the rest is very straght forward. once you have it all setup, just disconnect the power and plug it in your network. if it does not work, you can just take it out and re configure it

why did you share the connections? wait how did you share the connections? do you have two NIC's?

just plug the connect the modem to the WAN or Internet Port on the modem, then connect the two computers via ethernet, using the computer ports on the router, or via wireless, by connecting to the name of the wireless network hosted by the router

PS- DO NOT forget to change the password to your router and put a password on your wireless internet

Happy New Year!

Brian I reset the router and am able to log in to set it up, checked all of the settings, rebooted, still no internet.



Viking -see above, was setting up router, lost connection, thought I needed to run the network setup wizard and from what I gather, this caused XP to act like a router. Only have one NIC in the XP computer, so I believe I have created a loop. I can log onto the network wirelessly, but no internet connection on the Vista. Status on the Vista machine says the connection is Local Only, not Local and Internet.

Do you have a internet connection on the XP computer?



What is the gateway set to on the Vista computer? It should be set to the address of the router.



Are the PCs set to receive their IPs via DHCP?

ok. try connecting it again to the modem but unplug the modem for 30 sec. this will reset the dhcp and allow the device to pick up a new one.

Ax: No internet connection on XP, gateway on vista is the same as the router, both show that DCHP is enabled.



Brian: Unhooked modem for 30+ seconds, checked again, still getting the same ip of 192.168.1.2 with gateway of 192.168.1.1



Keeping in mind that I cannot get an internet connection even when I hook the modem directly to the new Vista, could it be that my modem is not communicating to the computer? RR and my local cable yahoo's tell me that the modem is functioning and is not the problem. They say it is the router, and blame that even after I tell them that I have tried the modem to computer connection on both pc's and can't get a internet connection that way. Would they be able to see communications to the modem and then to my computer, or can they just check the modem and see that it is receiving info from the cable company. This may be very basic, but I am just really frustrated with the entire situation.
