Given the choice, I'd definitely choose a cable for anything I know will require high internet usage. Wireless is just too slow, even on a 5G connection.

I still remember I once broke my Windows installation (young me had tried dual-booting the Windows 10 beta and my Windows 7 installation). I had to get system restored discs from the manufacturer. It wasn't particularly tricky to fix, but it took a long time to download those Windows updates after it finished. I noticed an immediate change once I remembered I had an old 30 ft. ethernet cable lying around and plugged it in. (This was maybe 8-10 years ago.)

Who buys a $300 home wifi box? They're $50-100

Wireless data links should be the exclusive domain of temporary, nomadic and/or sacrificial applications.

If the channel is permanent, static, or critical; as much of the path as practicable should be provisioned with constrained energy transmission.

I spend a lot more money on good Ethernet switches. But at least that works and is easier to manage than Wifi.

I set up a mesh router pair a while back - super easy setup, and the speed is good enough to have multiple TVs streaming at once, and without needing to run cables between rooms... Worth it.

That one in the picture is $599 isn't it?

I'm seriously thinking of getting a usbC-ethernet dongle for my mobile, for when I'm at my desk.

I got a used 10Gbe switch and a thunderbolt 10Gbe adapter for my computer and now I can transfer my videos and photos from my NAS like it's my internal hard drives.

It can also do 2.5Gbe which pretty much future proofs me.

6.99 is just one cost though. If you're needing ethernet actually done in walls then you're going to be paying a lot more than an access point.

Unless you need 6ft of cable or you just run wires on the floor it's more like $200 of plenium rated cable, and keystone jacks and the labor involved with the run.

My house with a half finished basement (easy access) took probably 16-20 hours running to 5 rooms.

But that cable can't summon Kel'Tuzad unlike the router.

I have about 6 or 8 ethernet cables in use plus more in my spare cables box, and I don't remember ever paying for one. Where do they come from? I never seem to run out.

Phased arrays are not a joke. You can get ridiculous dynamic range with those
