Let's see that ethernet cable do orthogonal frequency-division multiplexing...

Dude I just bought 4 refurbished Linksys MX4200 (tri-band) access points for $80 (total), put on OpenWRT, and built a mesh system. I'm incredibly happy with the result, especially for the price. And, I've got wireless bridges all through the house so I can keep some things off the forwarding channels and only in the back haul.

It's not wired, but it's close enough and doesn't require me drilling through all my walls running cable or carving out a space in the house for all of it to coalesce.

Granted, I'm in an area with not a lot of wireless interference...I work in enterprise networking and I've had a lot of issues with remote workers on wireless networks that weren't capable of handling the volume of data that the users were uploading. Sometimes just because there's too much interference...but a lot of the time it's because of misconfiguration (either out of ignorance or because the good features, like multicast-to-unicast, are missing), or printer drivers that spam the wireless with multicast whenever the printer is offline (which I've seen a surprising amount of times).

If you're on wireless...multicast is bad, mmmkay? Only "one" device can talk at a time on wireless (barring MIMO shenanigans), and when it's multicast traffic...it has to get sent at the lowest compatible rates. A lot of routers set this to 6Mbps or even 1Mbps by default. So your nice fancy "1200Mbps" wireless has to slow down a crawl every time your Roku wants to tell Alexa that it's there. Which is surprisingly often. Scale up for all the internet-of-crap stuff people have and it's a miracle their wireless works at all.

Oh and I've found people with extenders they don't know about. Ring Chime? Apparently it functions as an 802.11n (only) extender. Huge bottleneck right there. And then it can only be as good as the signal it gets from the next access point.

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

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 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.

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

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.

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.

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.

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

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