Do you have any issues if you take the firewalls down completely?
Do you have 2 firewalls running at the same time on both computers? or you have Windows on one and Kasp. on the other? If its both firewalls on both computers, turn off Windows and see if that clears it up.
If not, what I would do is connect them both wired to the router, remove all firewalls and rebuild the sharing. See if you still have the issue of sometimes there sometimes not. If it runs fine for a day or so then start adding things in, like go wireless on 1 computer give it some time if all is good then add something else in. At some point you'll probably find the issue.
My opinion on firewalls. If you own a router and the NAT firewall is turned on and you don't have a PC in the DMZ there is no need to have windows or any other firewall running. All you are doing at that point is stopping people already in your network from getting on your PC. If someone is good enough to get past your router then they are good enough to get past your firewall. Again this is my opinion and others may disagree, which is fine.
Hope this helps
