 I prefer to run higher quality wifi access points (AP) than the all in one type routers.   My current router is X86 based running Linux Nftables on bare metal and Bind9 and Kea as well as some other services in Docker on a VM. I prefer to run higher quality wifi access points (AP) than the all in one type routers.   My current router is X86 based running Linux Nftables on bare metal and Bind9 and Kea as well as some other services in Docker on a VM.

 Ultimately, what is important is the actual performance is the wifi system is satisfactory.  I have tried to help improve performance by moving as many as reasonably possible services to wired Ethernet, there by reducing bandwidth used on wifi and the use of 2 wireless access points connect upstream via Ethernet, which gives better wifi radio coverage and helps share wifi radio bandwidth. Ultimately, what is important is the actual performance is the wifi system is satisfactory.  I have tried to help improve performance by moving as many as reasonably possible services to wired Ethernet, there by reducing bandwidth used on wifi and the use of 2 wireless access points connect upstream via Ethernet, which gives better wifi radio coverage and helps share wifi radio bandwidth.
  
-The current access points are Netgate [[https://www.netgear.com/support/product/wax206/|WAX206]].  They only went on sale circa 2021 and went end of life early 2025, I am disappointed with Netgear for such a short support period.  Strangely the less featureful and powerful WAX202 still seems for sale at Netgear as of writing March 2025.  The WAX206 has a dual core aarch64_cortx-A53 running at up to 1350MHz, with 256MB NAND Flash and 512MB RAM.  It has 4 x 1Gbit ethernet ports and 1 x 2.5Gbit ethernet port.  The WAX206 does not have a USB port.  There is a currently supported [[https://openwrt.org/toh/hwdata/netgear/netgear_wax206|OpenWRT]] operating system solution for this wifi router.+The current access points are Netgate [[https://www.netgear.com/support/product/wax206/|WAX206]].  They only went on sale circa 2021 and went end of life early 2025, I am disappointed with Netgear for such a short support period.  Strangely the less featureful and powerful WAX202 still seems for sale at Netgear as of writing March 2025.  The WAX206 has a dual core aarch64_cortx-A53 running at up to 1350MHz, with 256MB NAND Flash and 512MB RAM.  It has 4 x 1Gbit ethernet ports and 1 x 2.5Gbit ethernet port.  The WAX206 does not have a USB port.  There is a currently supported [[https://openwrt.org/toh/hwdata/netgear/netgear_wax206|OpenWRT Techdata: NETGEAR WAX206]] operating system solution for this wifi router.
  
 My old wifi access points from 2014 were [[https://www.netgear.com/support/product/ex6200/|EX6200 – AC1200 Dual Band WiFi Range Extender]] gave me good service until I updated in 2022 to the WAX 206 units.  The EX6200V1 has has a dual core aarch64_cortx-A53 running at up to 800MHz, with 8MB NAND Flash and 128MB RAM.  It has 5 x 1Gbit ethernet ports. It has 1 x USB 3.0 port.  Only having 8MB flash capacity reduces the 3rd party opensource operating systems available. openWRT does not have a solution and dd-wrt only has a limited solution. My old wifi access points from 2014 were [[https://www.netgear.com/support/product/ex6200/|EX6200 – AC1200 Dual Band WiFi Range Extender]] gave me good service until I updated in 2022 to the WAX 206 units.  The EX6200V1 has has a dual core aarch64_cortx-A53 running at up to 800MHz, with 8MB NAND Flash and 128MB RAM.  It has 5 x 1Gbit ethernet ports.

 I always setup my Wifi Routers as Wifi Access Points (AP) using an Ethernet uplink only, also know as "Dump AP" or "Bridged AP".  Effectively the AP becomes an extension of my LAN and all the providing the Wifi functionality, all DNS, DHCP, firewalling, NAT functions occur in the upstream Ethernet wired Router. I always setup my Wifi Routers as Wifi Access Points (AP) using an Ethernet uplink only, also know as "Dump AP" or "Bridged AP".  Effectively the AP becomes an extension of my LAN and all the providing the Wifi functionality, all DNS, DHCP, firewalling, NAT functions occur in the upstream Ethernet wired Router.
