FIRST

=====

Go to DOS, type ipconfig - check all your network settings.

 

 

SECOND

======

Try loopback on the PC - i.e. ping 127.0.0.1 - see if you get a response

 

 

THIRD

=====

Try pinging computer names and testing name resolution i.e if the PC is called MAINPC on the network, type ping MAINPC in dos.

 

 

FOURTH

What are the IPCONFIG results for the laptop?? Seems odd your name resolution isn't working...

Cannot now ping home computer, I think onboard network card is faulty?

Have no PCI slots available!!

 

Is there another way too network 2 PC`s together, eg via usb ports maybe?

Ahh! Get a pair of these (one for each machine) and the world of wireless networking is open to you (they are fantastic - I use them at home)...

 

100m range, ideally no more than 60m in my experience though - works through walls, doors etc.

60m is a little optimistic, mind you, my walls are 2 feet thick stone!

Don't forget, when you go wireless, to set up your router to only allow access for the mac addresses for your PCs and change the default passwords to access the CLI. If not anyone can use your connection and access your information.

tis true jeff, i have a pda with wifi, and i'm always amazed at the number of kind people who allow me to use their wireless network all over the country

Unwittingly kind

 

Also forgot to mention that I believe the default passwords are all the same so anyone with any knowledge about routing, well you are practically authorizing access...

 

And don't use any obvious passwords or birthdates... use numbers in place of letters zero for O or 1 for i and special characters.

 

I know its obvious but better to be safe.
