Trying to carve out a new network on a home LAN

I have a home LAN that includes wired and wireless. I wish to set up a lab that will all be wired into something and connect to the main LAN via an extended wireless setup.  So I have my main wireless router connected to the Internet and it talks to the lab wireless router in the basement wirelessly. The lab router is an extension of the main wireless LAN. This all works OK.

What I want to do is to keep traffic on the lab LAN within itself. I don't want to have all of that traffic routing up to my main router or affecting other devices that live on the main router, unless I am taking lab traffic to the Internet or I am communicating with the lab from a computer on the main router. So lab1 and lab2 devices should be able to talk to each other without impacting PC1 or PC2 that connect to the main router.

I had purchased a Netgear FVS318G to create a whole other segment that I could then route. However, I keep having trouble getting it all to work together.  I can get the devices talking to each other, but not have full routing capability into the main LAN or vice versa. It struck me that perhaps I bought something that's really more complex than I need and perhaps the complexity of the device is messing up what I am trying to do.

So, one question is: is there some way to do this simply. I know that the FVS318G will probably work if I get it configured properly, but it's becoming almost not worth the effort because I think the device has more features than I really need that are complexing my efforts.

Would a smart switch be the answer, of if I just hook a dumb switch to the lab, is that enough? I experimented with a dumb switch this morning and mostly got it to work, but to have full functionality I had to point the gateway of each lab device to the IP of the main router.  In that scenario will the dumb switch keep lab traffic between lab devices within the switch or will it still have to go to the main router and then back again?
