I have problem with connection on my laptop.
Internet works well on computer, but there`s problem when I plug cable in laptop. It is written: "There is no or limited connection". Before that, there is written "Invalid IP".
I thought there is problem in laptop, but I reinstalled operation system. After that, everything worked fine until i did not conect internet cable on my computer.
How can I fix this problem? Why is there written "Invalid IP"?
I am using ethernet connection.

Modem: Motorola SB5101E SURFboard Cable modem
XP SP2

Welcome to TSG.
For starters,do a power on reset of the modem when you recable or re do any connection.
(power off /on the modem)
See if that changes your scenario.
It would also be helpful to know make and models of your modem and if any router is involved here..

[Alex030102]

I did everything you said. Nothing changes.
There is no router.

Is your connection to the modem USB or Ethernet. I know with that modem there is a installation CD that comes with it. Did you install it?

[Alex030102]

Yes, i installed it, but CD is needed for USB, not for ethernet.
My connection to the modem can be through usb and/or ethernet.
