[i and V]

hey everyone, i got a huge problem... i figure i'd post my question here since there seems to be more ppl here then at cable/dsl boards...
anyway, im using cable modem and windows xp and as of yesterday for some reason windows screwed up and is setting it's own ip! i called optimum online and they told me that they should be setting the ip for me to use and not windows. so i reinstalled windows but that didn't help...
does anyone know how to fix this? it's really confusing... i mean when i go to the connection icon on the task bar i can see that there's info being sent and rcv'd but i can't connect to anything... and it's not ie b/c i tried aim, aol, telnet, and even ran ip config and nothing... basically i have an ip set by win and not by opt. online...
thanks!

Welcome to the forum i and V..........................

Have you powercycled your modem?

If under IPCONFIG it has the wrong IP address

Type in: ipconfig /releaseall

Then: ipconfig /renewall

Now type: ipconfig /all

What IP address are you getting? 169.X.X.X ? If so, you are correct - Windows is setting the IP. However, this indicates you are having some kind of communication problem between your machine and your ISP's DHCP server.

BTW, I believe the command Speedo mentions, ipconfig /renewall should simply be ipconfig /renew. Try both if the first one doesn't work.

I got those instructions from ATTBI directly when I had the same problem he has, It worked OK for me, But who knows..............

i tried to power the modem on and off...
i'll try the ip commands when i get home...
and the ip that windows is getting begins w/ 172...

172.x.x.x !?!? Make sure you have you IP Configuration set to automatically receive address (I forget exact wording) instead of manually setting the IP address.

I'd get the cable companies setup instructions and run through them for the TCP/IP settings. If that doesn't fix it, you may have a defective NIC, cable, or modem. I'm somewhat stunned that the cable companies support doesn't have a "cookbook" walk-thru that they do to get you back on-line!

I'm suprized they just left him hanging there, Attbi will stay on the phone and walk you thru it.............
