connecting 2 laptops

It looks like you might have inadvertaintly created two seperate networks, one is using Workgroups you said this> i made workgroups on both pcs,

If you want to use Homegroups for sharing you only need to set up a Homegroup not a Workgroup type of network, using the "Home" network location works best with Homegroups if you want to use it.

But you also created a Homegroup > made homegroups and set documents, printers, viodeos, ... to share,. You need to use either Workgroups or Homegroups for your network but you can't use both.

That is probably why you show dual networks. You will need to delate one of them. I would delate the Workgroup go with Homegroups because it's made just for Windows 7 machines.

It's probably best to start over at this point by delating the Workgroup and leaving the Homegroup on all machines, then create a new Homegroup and join it from the other PC's.
Homegroup - Leave
Homegroup - Create
Homegroup - Add Computer or Join

If you are using an Anti Virus software or third party firewall it may be better to uninstall them until after you get Homegroups up and working correctly.

If you want to use Homegroups follow this trouble shooting guide to make sure it's set up correctly.
