I only have router suggestions for 1.6 GB fiber

I use an asus GT-AXE16000 which has a 2.5 GBe WAN port, and supports 2 10GBe ports, wired to my computer with a 10GBe adapter. I have 1.4GBe bidirectional fiber, and get the full bandwidth to my machines that connect 10GBe.

It’s wifi support is unbelievable. I use a AI mesh with it, and it covers the house, the yard (wifi sprinkler in the garage, and wifi pool and hot tub) and every smart device (around 100 total). Supports wifi 6, my phone transfers 1000MB/sec both ways over wifi.

Complete features, including an AI firewall that’s stellar. Expensive, but very worth it.

This really depends mostly on the capabilities of your devices. Just getting a better wifi access point/router combo won’t help if your devices can’t do any of it. Most devices are 2x2 MIMO and only support 80MHz wide channels on the 5GHz band. If you have a wifi 6 client (assuming you have a wifi6 router), the max signaling rate is 1200 Mbps, which translates to about 800 Mbps accounting for overhead. You can almost double this if you have devices that are capable of 160 MHz bandwidth but that is very rare, or if you have 3x3 MIMO capable devices (just as rare). Wifi 5 devices won’t get much better than the already quoted 500 Mbps. If you have wifi6e devices (just as rare) and a wifi6e wifi access point/router combo, you can also break the 1 GHz barrier. Wifi above 1 Gbps is still an expensive proposition.

ASUS axe16000 has WiFi 6e support. Of course you WiFi device will need to support WiFi 6e. The iPhone 15 pro series does but not the regular 15. Otherwise wire it but you pc will need to support multi got as well. Maybe a usb c adapter that does multi gig
