I understand the frustration but please be assured that once a data packet leaves the wifi access point and joins the physical network it is stripped of all the wifi information & headers and becomes just a regular packet. It has no memory of its journey via wifi or any other encapsulating packet along the way.
You have changed your router though - that is a physical network change. The settings may (or may not) be the same but as a consumer router it will only expose a fraction of the actual settings through to the end user. Add in the internal changes, architecture differences, security and firmware revisions your new 'router' will behave differently to your previous one.
The frustration of consumer-focused 'routers' (typically not just a router but an all-in-one network device), such as those made by Asus, is the reason many of us buy a more enterprise focused 'pure' router so that we can see and change every little detail.
Are we ready to focus on the physical changes of your network introduced with the router and firewall part of your new Asus device?
