Limited or no connectivity - need help

[wei]

I had been using a wireless connection to my Verizon router, and it
was working fine for months. Suddenly the wireless connectivity was
lost because the USB/ANTENNA plug in stopped working. I proved this
by trying a USB plug in from another machine - I had connectivity just
fine on the problem machine.

Since I lacked a spare plug in, I removed the bad one and connected
the machine to the router with a CAT5 cable, a method I used til last
year.

Somehow the CAT5 connection now fails - I show a yellow exclamation on
the task bar icon and it says I have 'limited or no connectivity'. In
desperation I reinstalled a fresh copy of XP SP3 to start over from
scratch. I still have the same problem somehow, which surprises me
because it is virgin installation of a new XP OS.

What on earth have I done?

Are you using a cable that you know is good?
Are the mobo NIC drivers installed?
Does Device Manager show any related errors?
Is the Ethernet port enabled?
Do you have an IP address on the correct subnet?
What does 'ipconfig /all' show?

Not an exhaustive list above, just a few things to get you started.

Embarrassingly I have to report that the cable was bad. :<(

Why you did a reinstalled XP SP3 for,
Now you are unable to do a System Restore,
back to August 21, 2012 to fax the problem..

Now you have to call Verizon for help to reinstalled your router..

Have a good day

No need for embarrassment. I'm glad to hear that the fix was
relatively easy, once you found the problem.
