2 adapters 2 networks

[fierce phoenix]

I am using an old Wireless G PCI card Nic and a 10/100/1000 Nic (on board) I have connected them to 2 completely different networks both networks have their own WiFi router/modem combo. network A has 6 Mbps DSL (Wired) and Network B has 20 Mbps Cable (Wireless)

Which one will my system use? I have always heard Wired trumps Wireless.

I know if I have 2 adapters connected to the same router spanning tree will decide which one to use but in this case there is a single connection to each network.

This will depend how the routing table is configured. You can check this with ROUTE PRINT from a command prompt (assuming Windows). One of the two NICs will have its default gateway on the 0.0.0.0 address.

Yes, I believe wired Ethernet will by default be the priority since it has a lower cost of operation.

I'm not sure which one Windows prioritizes by default, but you can change the priority order manually.

Wired always better when talking on the LAN, once your data goes to WAN, it's all down to the connection speed, and external network configuration.

If you want to use both to load balance ... http://www.sortbyte.com/software-programs/networking/network-manager
