Hi John.

Not sure if you got answers to your router question, but it's yes you can - and it's pretty easy. I bought the Z21 around the time your asked (through DCC concepts as it so happens) and am very happy with it after sorting out 2 issues with it. One was getting the existing router working, the other to program the Cobalt point motors (de/activate the self-centring using fixed accessory addresses) . Both I solved pretty quickly. The connectivity of having Loconet and RBUS (=express-bus) is great giving access to cheap current detection, servo control and so. The short protection is very good.The 3A amp capacity is pretty good too - goes a long way for me in N scale with the Cobalt IPs just nipping from it.

Steps for setting up the Z21 for your own router
The Z21 is by default on address 192.168.0.111 and because routers often only see 256 addresses in a range of addresses such as 192.168.0.xxx, it may not 'see' your Z21.

The solution then is to either [A] change the Z21 address into the visible range or change the address of your router into the 192.168.0.xxx range. My router was setup with 192.168.1.xxx range. After changing my router's address from 192.168.1.254 to 192.168.0.254 it all started working.

As said, you can also change the Z21's address by using the Z21 maintenance tool that Roco supplies. The tool PC only but I run it also on my Mac using CrossOver. I haven't tried the address changing - only spotted the option. It comes with a warning of that you may make your device unreachable after you program it and that they (Roco) can not support you if you do.
