I use home network for all PCs, but I also set laptop can connect to internet directly without network though all the connections are through the same broadband. The reason I allow independent connection for laptop is in case when home network lost(the hub is not stable, and I don't have time to buy it yet ), laptop can still connect. I have some doubts here, -- How I know which connection the laptop is using? I guess the direct line is faster, but how I set the laptop to go through the direct connection?
