Re: [H] Dual Networks
Wow! That worked. Changed the metrics to 1 (LAN) and 100 (Wireless), then pulled the internet on the lan and still have internet access and can still print. Excellent job, Jamie!

Try changing the interface metric like I said below. By default Windows will prefer a wired connection over a wireless one. I don't know if that will work or not though but it's worth a shot.

Re: [H] Dual Networks
If you have two networks (with different IP blocks) then it should work fine: NIC 1 - 192.168.1.x NIC 2 - 192.168.2.x T
