My favorite!

No this is Patrick.

Where are you finding then for $25-$35? Ebay has them going for $70+

Check your firewall logs (Status -> System Logs -> Firewall for pfSense, can’t remember for opnsense). I’d suspect you might see blocks from 10.0.66.x to your Playstation.

Of course.

Do either routers support going into what’s called an AP access mode instead of router? If they do then you could put one into access point mode and run a patch cable between the two.

You may also be able to load DD-wrt on them but checking https://dd-wrt.com/support/router-database/ it doesn’t look like either have support.
