@aorus1 Thanks for your inquiry. We’re looking into adding support for WiFi 6 capable hardware. However, that’s going to take some time.
For the time being, if you have a powerful WiFi router already, one plausible solution is to use your existing WiFi router as an Access Point. Connect to the pcWRT by wire and turn off WiFi on the pcWRT. Since WiFi is shifted to your existing router, the Newifi D2 (with dual core CPU, 512 MB RAM and hardware accelerated NAT) should be powerful enough to handle most needs.
