Or instead of being a penny pincher get an AX wireless router and not contribute more ewaste.

Which would you recommend?

The AX series is the current TP-Link offering for most use cases starting at ~$80: https://www.newegg.com/p/pl?N=50012120%20100158096%206013568... In addition, the AX3200 Belkin (RT3200) is $100, and the $140 Linksys (E8450) are both listed as supporting OpenWRT.

The Dell N1100 is a nice switch, but a relatively new product ( Below is my survey response to their support feedback request: 1) The products should not have a built-in time-bomb that causes them to stop working after only a few years. 2) Dell should have informed us of this issue by email. Instead they left a very "phishing" like voicemail on a manager's phone. (Not the phone of the registered point-of-contract for…

(Post Author here)

The non POE N1100's are fanless, Thankfully don't really contain any features that would require licencing, that being said also has no hardware Layer 3 capability, so not really in the same class as the N3XXX or N2XXX's

The licencing thing does suck though, that's poor from Dell who normally (at least switches wise) do a reasonably good job for the price.

Minor Quibble: £85 is not a cheap ethernet switch. It's an entertaining and informative read, but it's more like low-end datacentre hardware than that cheap €25 switch I've got in my home office. A little disappointing as I was hoping I'd have a cheeky high-bandwidth raspberry-pi alternative on my hands ...

It's an amazingly cheap 10g switch. (It has 4x10g along with the 1g ports). It's even a very cheap fully managed switch.

It has zero 10g ports:

  N1108T-ON: 
  1GbE Port Attributes Multi-speed:
  8x 10/100/1000Mbps half/full duplex RJ45 ports
  1GbE Port Attributes Single-speed:
  2x 1000Mbps half/full duplex RJ45 ports
  Integrated 1GbE SFP dedicated ports: 2
  Integrated 10GbE SFP+ dedicated ports: N/A

My main thought reading this as a non-network admin was of Mr Robot, and all the Linux installs on low level hardware used for hacks on that show. Very interesting read and lots of upside to what is discussed, but the thought of the uncountable, almost invisible operating systems running in a large network give me a odd feeling in the pit of my stomach. So many potential places for malfeasance to hide.

They're not potential; do you know about Intel ME, cellphone baseband firmware, Apple's new on-phone CSAM scanning plans, and yellow printer dots?

I've used these for over a decade with limited success. Their performance is very specific to your wiring and can be fouled up with lots of things. Mine was sometimes no faster than WiFi. MoCA (Ethernet over coax wiring like for cable/satellite TV) seems to work better.

I had a lot more success with them after popping my electrical panel open and rearranging the relevant outlet circuits to all be on the same AC phase (making sure not to unbalance the amperage load since some were 15As and some were 20)

I can't believe I haven't thought of that!

I'm using a pair of TPLinks to feed a wifi router on the opposite side of my house. The outlets are definitely on opposite phases, but the powerline adapters still work reasonably well. (~80Mbps). Now I'm realizing I should probably swap a couple of circuits and improve that connection.

My mistake. OK, it's just a reasonably cheap fully managed switch (at 85 pounds, anyway).

It seems like at least the TP-Link AX50 won't have openwrt support anytime soon (or more likely at all), so even worse for long usage times.

Intel ME and cellular baseband are particularly worrisome. They are essentially separate and inaccessible (outside of very restricted APIs) systems with their own CPU, running their own OS and applications with the lowest level access to all hardware.

Off-topic, but I just learned about another, practical networking utility, yesterday. "powerline adaptors" [0] Basically, buy these adaptors and for ~$100, you can have create a "wired" LAN connection using power outlets in a home. [0] https://www.techradar.com/news/the-best-powerline-adaptors

It would be more practical in many places now to use leftover "hardline" phone plugs, especially because when they are disconnected from service they are sometimes quite literally disconnected and you have much fewer concerns about bleedover into neighbors.

Speeds won't be great for that sort of ethernet-over-phone wire, especially because most landlines used awful, cheeap wires, but in some cases it is faster than powerline adaptors.

Unfortunately all the companies that produce such equipment for "phone line adaptors" sell only to the phone companies and never directly to consumers.

So many houses today have vestigial phone wires that no one is using for anything.

Thanks for the correction!
