They don't get it

When I was 15, my dad purchased me a plaster saw (still have it) and handed me his drill.

Then told me to make it look neat, but "don't fuck up because your mother will kill us both".

I ran about 4 network points through the house.

Nothing like fear to produce a 100% perfect finish 😉

And then there's me who just screwed up installing a new door knob. I stripped the threads on the screws cause I used the wrong size screws drilling. Now if the new knob fails in the future, I need to buy a new door lmao
- If it's a wooden door that you're screwing into, dab some match sticks with a little bit of liquid nails and gently hammer them into the stripped-out screw hole, and cut them flush with the hole. Once the glue dries, you can drive the screw back into the matches and it'll have enough wood to bite into.
- If you can, re-use existing sockets! Old telephone or antenna lines can work! You tie the cable to the end of the old cable and pull it through the existing PVC pipe.

Go ahead and pull em in the wall! Don't be scared. Worst case the world is ending anyways

For me it was like

Join forces and do link aggregation for double the speeds.

A tale as old as time. Before Ethernet cables we were running phone extension cables through the house to connect up the modem to the only phone jack.

I did this for every device in my house. used flat ethernet cable and just fished it under the carpets. Was significantly cheaper than trying to make wireless reach the other side of the house.

Flat ethernet cable
What?!! I did not know this existed!!
- Yeah they're great! I got a super long flat white one and those little white plastic staple things you can lightly hammer into the wall, and ran it along the baseboard of the walls, makes it nearly invisible! It was a bit tedious to do (which is why I haven't yet redone it in the place I live now, although I will), but honestly I super recommend it. My partner wanted to try and run cords through the walls but I was way too nervous about what might go wrong, so found this solution instead lol
- You can also buy devices you plug into the wall and route your network through your power network. Used them to give my detached garage wifi. Works pretty well.

I had to buy carpets to hide the cable under them when running across the floor. Only exposed parts go through the doorways, and the wife complains about them. Well, I am not complaining about our craptastic wifi anymore.

If you own your house you could learn to pull cable and how to do punchdowns. It's not a super difficult job. That way you could impress the lady of the house with your technical skills while also hiding the mess.
- I'd be careful giving broad advice like this.
  In my country (Australia) it's illegal to run cabling yourself unless you're a registered cabler.

It's either deal with the distance with a wireless network (which can't even reach my current bedroom in my house) or deal with concrete walls that also cuts down the Wi-Fi signal in my new bedroom.

Then again, my home's network is due for an upgrade because it's 17 years old, so I just need to convince my family to upgrade to CAT6 cabling and a faster Wi-Fi router.

You could just use 2 Ethernet Over Power adaptors (not to be confused with power over ethernet).

After all, it's not as if the powerlines aren't already installed at home and connect all power plugs with all other power plugs.

This isn't even new: I've been using this solution for about a decade, back when it could do a mere 20Mb/s (which was still way faster than my Internet connection could handle back then ;))

Unless having a 500Mb/s limit on bandwith is somehow unacceptable when you could have Gigabit ethernet. Then again, why not fibre all the way ;)

Have you ever paid attention to packet loss?
Honest question, because I'm an electrician and Ethernet is so fickle, I've always assumed it would play hell on the overall quality.
- The whole thing is layered into multiple levels (go check the OSI Model and its Layers on Wikipedia if you're willing to go down that specific information hole ;)) and the physical layer should mainly be handling packet loss on the connection between those adaptors, transparently to the higher layers that just see that as lower bandwidth than the spec for the adaptors (a spec which is really quite optimistic, IMHO).
  Yeah, a cable with a metal sheaf wired to the GND level (i.e. Cat cable) is going to be way better at higher frequencies and at isolation from noise that two twisted copper wires were the network signal is shared with a different "signal" which whilst generally 50/60Hz (depending on country) can have spikes and noise at other frequencies, so it's never going to be the same.
  However for example at home right now I can get a reliable 100 Mbit/s over a pair of those adaptors from my router to my PC and the speed limitation is actually (I believe) from my old router not supporting Gigabit Ethernet rather than from the adaptors which are supposed to handle up to 500 Mbit/sec.
  That said and as somebody pointed out, it only works well if the plugs you're connecting are on the same electrical network, as transversing coils isn't exactly great for high frequency signals.
- It definitely can be finicky. I had a portable ac that completely killed the power line ethernet connection when it ran. And my current house I have it in i use from where my router is to where my main TV is and it is unreliable even without that AC unit. So it definitely depends on the circumstances.

I always wonder if I’m introducing bad latency by running a 100 ft ethernet cable.

Then I remind myself it’s the speed of light.

Mine runs from the top floor all the way into the basement!

Do y"all not use the magic adapters that you plug in by your router, then by your PC to make a lan cable out of the electric wiring? That improved my cable management so much

Power over Ethernet adapters have some serious limitations. MoCa adaptors which use existing coaxial connections, even if you have cable internet, can provide greater speed and better latency than Poe. To be honest though, copper ethernet or fiber ethernet or generally the best way to go.
Drill through the walls or be lazy and run a cable over the roof
- To clarify, powerline adapters are what you mean. Power over Ethernet is just that, providing a current over an ethernet cable.

How many are 100ft?

30 meters.
- Thanks
- 30,48 meters.
  Come on, be accurate. The metric system isn't based on random body parts or things laying around that came in handy once upon a time 400 years ago
100

Do people not know power line ethernet adapters are a thing? Look if up on Amazon, you just plug one into the wall by your router and one next to your PC. Clean and strong connections.

What in tarnation is this black magic? I don't know how I've never heard of these before.
- They're good/reliable enough that it's worth the £20-30 to try a set out. Although like another guy commented bad wall wiring can sometimes have effects if your router is really fast, I get my full 11MBps through my walls easily enough in relatively old housing.
