I have two (onboard) ethernet adapters that I would like to use to access both a LAN (used to communicate with a highspeed camera) and the internet.
After implementing recommendations from these two threads: Multiple network connections on Windows 7 and Ethernet (intranet) and Wi-Fi (internet) to work simulatenously, I've still only been met with limited success.
I have the adapters configured as follows
LAN
Default Gateway: blank
IPv4 Address: 192.168.0.1
Subnet mask: 255.255.255.0
DNS: blank
Internet
Default Gateway: 172.79.72.1
IPv4 Address: 172.79.72.127
Subnet mask: 255.255.255.0
DNS: 172.79.2.1
I have the interface metrics for the LAN and internet set to 1 and 2000, respectively. In addition, in Windows 7's advanced networking setting I have the LAN adapter set to be accessed before the internet.
This has all been done because whenever the internet connection is active, I (somewhat) lose connection with the LAN. I say somewhat because with the internet active I cannot connect to the camera through its software; however, it does reply to pings through the command prompt. What's more strange is that in order to fix the problem, not only do I have to disable the internet connection, but I must also reboot the computer. Simply restarting the camera software after disabling the internet does not solve it, so for this reason I suspect Windows is the culprit.
Here are my routing tables

Any help with this (very frustrating) problem would be greatly appreciated. Cheers!
