Using laptop as router for desktop "LAN" doesn't have valid ip configuration?

I used to hook up my desktop to the internet by connecting it with a wire to my laptop and then my laptop would share its wireless internet. I haven't done this for awhile and now i am getting this error. "Local area connection" doesn't have a valid IP configuration. on my laptop i have internet and on my laptop it says the LAN connection has internet. On my desktop it says it is joined/connected but has no internet access. I have tried several things, reseting routers, different cords, flushing dns, manually putting in ipv4 info. etc. etc. so many things. I can not get it to access the internet. Any tips are much appreciated and I will do everything you guys ask in order. even if i have already tried it. So please any tips. Here is a copy of my Ipconfig/all on my laptop.

Update:

Alright, I am looking in my routers firewall area. (att uverse) and i cant find where i can add ANY physical address. But i can allow myself to host specific applications. like Games, Servers, Phones. and other things. But cant find addresses in the list. Any ideas?

    Start by running cmd from the start menu

    Type “ipconfig /all” without the quotes

    Write down the physical address of which ever connection is/are not working. If you are hard wired to your router, then use the Ethernet adapter physical address. If you are running wireless, then use the Wireless LAN adapter. I had to do this for both.

    Go to your router's firewall and find the physical addresses of the connections.

    Find the physical address(s) of your blocked adapter(s) and unblock it.
