I wouldn't investigate too much time into the WRT1200 setup as long as it isn't sure that it can handle VLANs and open source software can configure it.

Usually, VLAN tags are just used inside a closed network. If data leaves the network, it generally is untagged (except you extend the "closed network" to some external devices such as another switch or a CPE with two or more SSIDs). By default WAN and LAN (external) ports are untagged, while the (internal) port/wiring between the physical switch and the CPU is tagged, b/c the CPU needs to be able to handle each packet, be it from WAN or from LAN.

The WRT1200 has to have two CPU ports, b/c it has two physical NICs (WAN and LAN are on an own NIC each) as you did found out. So two ports/wirings are needed anyway.

BTW: There is a nice picture of the WNDR3700 architecture in the OpenWRT hardware wiki, which shows port assignments:

https://wiki.openwrt.org/toh/netgear/wndr3700#switch_ports_for_vlans

It also has two separate NICs just like the WRT1200, but you can use VLANs on both NICs if needed.

Just received my wndr3700 v5 and wouldn't you know it there isn't a version 5 firmware available.

Sure it is. Supported since r49247, see https://wiki.openwrt.org/toh/netgear/wndr3700#tab__openwrt_support

I saw that but I can't see where to download the firmware.

BTW, in post #49 you asked for a recommendation, but had ordered the WNDR3700 already. I would have recommended a TL-WDR4300 or an Archer C7, both are supported by OpenWRT for a long time now. But WNDR3700 or even better WNDR3800 should be o.k. also.

If I can't get this one to work I'll return and purchase one of the recommended ones.

Got a TL WDR4300
and this is how the default interfaces are configured:

If I understood previous advisements, LAN should be eth1.01 and when I create a Guest VLAN it would be eth1.02. Is that correct?

No, eth0.1 is LAN, VLAN ID is 1. eth0.2 is WAN, VLAN ID is 2. They share a common physical switch interface (eth0) on this router.

Your guest network would be eth0.3, VLAN ID 3 or whatever eth0.x, VLAN ID x.

Have created VLAN ID 3 eth0.3 with static id of 192.168.3.1
Here's my Switch Configuration, however, it doesn't work as set up.. Port 2 on the Router is Port 3 in the Software. When connect ethernet cable to port 2 on router and to my computer then run arp -a in cmd window it does not come back with the static id of 192.168.3.1.

First you create an interface with name guest. Be sure to assign a static IP and a netmask:

Then set up DHCP, it can help to not have to change between IPs on your laptop/PC:

Now configure the switch. Port WAN (the blue one) is software port 1, so physical port 1 is sw port 2 and physical port 2 is sw port 3, right. I use port 2 as the guest port. Make sure your laptop/PC is connected to physical port 2 during setup, so you are still on the LAN after saving and applying. Make also sure the desired port is untagged member of VLAN 3 and no member of VLAN 1 anymore. Then connect your laptop/PC to physical port 1 and got to the LuCI web UI again. You have to use http://192.168.3.1/ now and you need to log in again:

That's it, your laptop/PC now is connected to the guest LAN (or else you can't log into the web UI). See network settings to find out the IP assigned to your laptop/PC:
