@techbloke, it’s frustrating when the guest isolation feature shows as enabled but doesn’t actually block access like it should. On my RT-AX58U, I noticed that sometimes the isolation only applies to wireless guests and not wired ones, so double-check if your guest devices are connecting via Ethernet or Wi-Fi. Also, some firmware updates introduce bugs that can cause this kind of issue, so switching to Merlin firmware helped me get more reliable guest isolation and extra controls without new hardware. That said, if you're not comfortable flashing third-party firmware, a quick workaround I use is setting up VLANs if your router supports it, which adds a more robust layer of separation. Worth exploring before diving into Merlin, especially since you want to keep things secure without extra gear.
