i am using a windows xp sp3 desktop and i am trying to get to my wifes Windows 7 gateway laptop. Both are on the same LAN and workgroup. i however can not ping her static address on her laptop when she is connected via wireless N to our the share router. i go into the router and see that she is connected but from the desktop i can not ping her static address by Ip nor by name does not work. i also tried going thru network places nothing. i am just trying to copy and paste files to her C$ drive. i tried turning off windows firewall on the laptop nothing still does not work.

Just curious why people in HOMES using a class A network and borrowing 16 bits for a subnet mask???? anyone explain that to me....

You would only do that if you wanted more subnets and less hosts... but that usually is not meant for a typical home LAN. Most of the time we use the Class C network with 24 bit subnet for homes to give us 255 hosts of course minus 2 for broadcast and gateway...

i get what your saying but i want to be different.

I mean there is nothing wrong with it at all. It is still a private used address but I have seen a lot of people from different countries use the Class A network. i was just always bogged by the idea......
