Yes, it is possible to set up two separate networks using two different routers.

The second router's WAN connection links to a LAN port on the initial router.
It seems there will be two different networks, each with its own Wi-Fi, firewall settings, and configurations. You’re wondering if your current router supports VLANs to create separate networks, but it doesn’t. It would be better to connect a newer router to an IPS switch or an older one depending on your needs. Your Asus router appears to have limited features compared to what you see online. You might want to upgrade to a more capable model like Netgear, though they can be pricey.
It depends on how you checked the setup. Did you verify if guests could communicate with each other and regular users on the standard network? Or did you assume everything was on the same subnet without realizing it might be segmented?
Because WiFi clients are usually treated as separate networks, the router can restrict communication between them or block access to other SSIDs. Even though they share the same IP range, segmentation by the router is key.
Since WiFi traffic isn't truly Ethernet, the router must efficiently manage this wireless layer, which requires a powerful processor to handle both WAN and LAN routing effectively.
It was some time since then, yet I recall it was a budget Trendnet N-band router. I managed to send a ping from the guest network to the main one—just a brief test.
