E:\>arp -a
Interface: 192.168.1.100 --- 0x6
Internet Address Physical Address Type
192.168.1.5 00-a0-24-cb-d4-84 dynamic
If I ping 192.168.1.6 which doesn't, I get this -
E:\>arp -a
Interface: 192.168.1.100 --- 0x6
Internet Address Physical Address Type
192.168.1.6 00-00-00-00-00-00 invalid
Note the Physical address is all 0's and type is invalid
If you get the former and the ping isn't working, the most likely cause is you have a firewall on the machine

Both XP firewalls are OFF.
Not sure what you mean by the arp -a. I type in ping 192.168.1.105arp -a and get told it's a bad parameter????

It should be
ping 192.168.1.105
arp -a
(ie separate commands, one after the other)

And write it on a sticky label and stick this to the router. This does not create a major security risk as if someone is standing next to the router all the wireless security in the world is not going to stop them plugging a piece of Cat 5 in the back of it.

You have first to mark the area that you want to copy. There is a button with a dotted sqare that you click then drag the white cursor over the area to copy. Then click the copy button.

Re: Help setting up network
The second ping is a loopback - ie PC pinging itself. How about the laptop pinging PC?
Also, can you confirm from the ipconfig /all on the laptop that the MAC address 00-02-3f-34-39-82 is correct. If it is, something on the laptop is blocking the ping - usually a firewall!
Another thing to try on the laptop is ping 127.0.0.1 (a loopback test), and also try pinging the 'problem' laptop from the other laptop.

Re: Help setting up network
Sorted
I'd turned off the XP firewall but still had on the AntiVirus firewall
One more time, THANK YOU Aragorn and all. Very sincerely appreciated
