6. Good so far

Good news on finding how to access the routers console. That will help enormously.

As far as the whitelist, that's normally used add exclusions to the firewall blocked traffic coming from the outside (Internet), not traffic originating from your private network (LAN). Personally, I'd check the router logs first. Assuming logging is turned on, it will show if anything being blocked by the firewall, along with a plethora of other potential problems. I'm assuming your firewall is built in to your router?

What's the make/model model of the router? I probably won't know anything about it, but it will be easy enough to get instructions.

FYI, there is flat Ethernet cable available, made to be easier to hide. I haven't tried it.
