windows 7, two connections, two subnets, lose connection on original

I have a gigabit connection to my Domain, using 7 x64 ultimate.  I typically program routers ahead of time before I take them to a client's, so I also installed two additional 10/100 pci cards.  

Unfortunately, whenever ANY seven machine (period) is connected to ANY secondary subnet, the original connection stops functioning entirely.  It shows both networks "local only" in network sharing center, however this is false as the original behaves disconnected.  There is also a new red X to the internet.

This is must be a very widespread issue as I have not encountered a win7 computer that didnt behave this way.

I also have a netbook with 7 x32 Pro, with a WIFI and 10/100 port.  If the wireless is connected as well as the LAN, to different subnets... one of them stops working completely.

I dual boot XP home and it works flawlessly.

IS this a strategic built in cripple on windows 7 ?  or is there a solution to this?  no change after sp1

Are they separate networks?  That is, different IP/subnet combinations?

i can then hit the second network upon connection to it, but the first disappears.

go into the network adapter, tcpip ipv4 settings, advanced, turn off automatic metric, and now add a metric number lower numbers have higher priority
