I have one router on my home network. This acts as the main WiFi access point for all devices, as well as being connected to a simple switch for my home lab. I would like to be able to isolate my home lab onto a different subnet, where all machines on this side of the network would have static IP addresses.

Is it possible to do this with only one router? I have been advised by a colleague that I can set up a VLAN and use this as a way to split the network up into two subnets, but I'm not sure i fully understand how this works.

Any advice on how to achieve this would be appreciated.

Thanks.

First of all check that your router is able to make VLAN;. If it is, give us a screenshot with your settings page. If it doesn't an option would be to install OpenWrt+LuCi ;) (if your router supports it), and then: http://wiki.openwrt.org/doc/uci/network/switch

A router functions on the 3rd OSI layer, on which communications occur using the Internet Protocol (as in, IP addresses). VLANs are a product of the 2nd layer, the Data Link Layer. You'll likely not have that functionality without using a switch in between the router and the rest of the network.

FYI - having two different subnets will require two different routers, even if your network is segmented into VLANs. Routers are how computers communicate across different networks. In short, you'll need a second router in order for the two networks to communicate anyway.
