Honestly you’re better off getting a non-wireless router and switch with sfp+ ports and back hauling them with 10gb transceivers, then just get a wifi6e AP. Microtik makes a real nice set of switches with dual sfp+ and multiple 2.5gbe ports.
Negotiating 5 gigabits was widely skipped to 10gb, which has more support than even 2.5gb.
Or skip learning what that all means and just get a wifi6e router with a 2.5gbe wan.
Yeah it’s crazy how it all stacks up. Back when I had all my RGB on, 2x pumps, 11 fans, with the monitors on my power draw at idle was almost 200w. Power prices here aren’t great so running my gaming pc 24/7 costs me almost $100 by itself each month. Planning on cutting that down greatly with this new server.
I just nabbed an amazing deal on eBay, a Dell Precision 3420 with a Xeon e3 1270v6 for $90. Gonna make it a headless server and hoping to get it idling around 30-50 watts. For comparison my gaming rig idles at a whopping 90-120w.
The BEST WAY? Run an Ethernet cable from your main router’s lan port to a simple unmanaged network switch, then run a cable from the switch to the basement, to a new router. Name the router the same SSID(wifi name) as the main router, same password. Wired mesh done. Router models don’t usually need to be the same.
