Hi everybody,
I have a linksys router and a cable modem connection. I have connected
two
computers, a desktop and a laptop. Everything had been working fine
until this afternoon when all of a sudden my laptop could no longer
connect to the internet.

I have had that problem before but usually if I reboot my computer and
reboot the linksys router and modem, I always get the connection back.
I noticed that my desktop could still connect to the internet, but no
matter what I do the laptop just can't connect to the internet
anymore. I have tried lots of different things, like moving the
connection to a different port on the linksys router, trying to
directly connect the laptop to the cable modem. But nothing is
working. Also, when I do an ipconfig/all, I see that the IP address I
get on the laptop is radically different than that of the laptop (even
the first 3 digits). I am guessing somehow the IP address on my laptop
got changed and it just won't change back.

Somebody please help!

It shouldn't matter if the IP address of your laptop is different. Your
router should be spoofing (copying) the IP of your desktop computer, or
whatever computer you had hooked up when the cable modem was first
provisioned. If somehow the MAC spoofing got turned off in your router,
then I would expect only ONE of your two computers to be able to connect to
the Internet. But most routers are smart enough to correct this problem by
themselves, if you turn on your hardware in the right sequence (starting
with all power disconnected and the laptop NOT connected to the router)

Plug in cable modem. Wait two full minutes.
Plug in router. Wait two full minutes.
Plug in desktop PC. Boot the desktop PC and make sure that you can access
the Internet OK.

If everything looks good, then plug the laptop back in to the router.

If that doesn't work, then pull out the manual for your router and see how
to set it to spoof the mac of your desktop PC (or whatever PC was hooked up
when the cable modem was provisioned) -Dave

Can the laptop talk to the desktop ?

What is the address. It wouldn't happen to be a 169.x.x.x type address
would it? If so then windows didn't actually get an address from your
router and it is defaulting to it's own address. This could be a symptom of
no wire to your router, or a bad one... Try a known good one. If that
fails, then for laughs try manual settings. Not sure what your numbering
scheme, likely 192.168.1.x, basicly the same as your working machine except
the last digit diffrent and not one.

If that fails then possibly reinstalling the network drivers might help.

Bad card in the laptop? Bad Cat 5 to the router? I'd look there first.
FWIW
YMMV

Dave, I did what u said but it does not still work. I know it can't be
the Ethernet card or the cable or the linksys port, because I got new
card and cable, and I tried different ports. Still no luck.

What OS??? If Windows XP, do start, control panel, network connections,
network setup wizard, then specify that you connect to the Internet through
another computer or gateway. The only thing I can think of is maybe your
notebook is no longer set up to access the Internet through the ethernet, so
try the above. -Dave

Do a Google search on lspfix.exe. This is a small program that resets
the layered services protocol in WinXP. Run it in basic mode, not
advanced mode, and reboot. See if that helps. I have had this same
issue recur from time to time on three WinXP laptops and this takes care
of whatever the source is.
