The router is WRT1900ACS. What's the AP make/model?
have max 3 devices streaming at a time we don’t use 4K yet but want to be ready for it.
4K from common streaming services is compressed and under 50Mbps, not a problem.
want speeds that max isp of 500mbs close to the router and will be able to cope with more at a later date
AC router can do that. For more you need to upgrade not only the router to AX, but your devices to AX too.
VPN firmware - use VPN/dns for streaming and vpn for sons PS5 gaming.
Home routers can do enough for streaming speeds. VPN for gaming - I don't know, latency is important for gaming.
spend max $300 but if a really convincing reason would go higher
Are you willing to reuse the WRT1900ACS router as Access Point? Are you looking for a completely new "mesh" Wi-Fi system?
