That's correct. For dual WAN router you should consider a business grade router combined with a wireless access points.

@D3C0D3R No big difference between these - AX1500, AX10.and AX15. They are all rates as AX1500. AX15 is the most recent router model.

@Nigelandre You have three options: 1. Use another C54 in RE mode (check this post). 2. Use a dedicated RE of your choice 3. Use another router in AP mode connected to C54.

@FishhyFishCakes Well, that was the point - to isolate guests in another VLAN (a different network subnet) so other users couldn't see them and vice versa. If you want this to work your main router...

@tkurtulus Check this post for recommended steps.

@FishhyFishCakes The only way to separate users in different networks is to use the Multi-VLAN mode configuration for TL-WA1201.
