you urge to be so correct
when your trying to figure out something you have to try things .. if you just say 'meh thats not it' than how do you know ? .. you have to bring it it down a notch really ..
i've been using / supporting and working on kai since day1 , i'm a moderator an administrator and an everyday user .. i don't 'urge' things to be correct based on nothing , i've seen uninstalling a firewall solve the same problem hundreds of times over the years ..
a firewall will block xbox system link traffic because its not 'standard' network traffic , the same reason that you need promiscuous mode to use wireless ..
how is your network now set up ? .. xbox and computer wired to a router ? ..
It is also set to my current router not the adapter.
what ? .. in the kai config it has a section where your network cards should be listed , pick the wired one.
