There are also the glass snakey bois that you could use.

If it’s anywhere near that long you should see a doctor.

Yes, it seems painfully obvious that the primary driver of new WiFi router sales, is WiFi overcrowding.

I would argue that the public needs to be better educated or at least saved from themselves with WiFi, however, nobody will be doing that. Having multiple lower-powered APs in a space can dramatically reduce how far outside of your premise the signal travels, and provide fast speeds indoors, however, it only takes one dummy to pick up a long-range AP, and put it in their apartment to ruin the wifi for everyone else around them.

Unless we start EM isolating apartments, or get everyone to start using modern lower-powered WiFi with multiple access points for coverage, things won’t change. I largely consider it to be impossible to fix WiFi in large buildings; especially established apartment buildings. No company is going to spend on 2.4Ghz and 5Ghz isolation insulation to be installed between units just for their renters to have better WiFi, and the general public as a whole… well, it’s basically a fool’s errand to convince everyone to do anything without government regulation, and bluntly, the government, made of the same idiots that make up the general public, isn’t any better and won’t be forcing everyone to “do it correctly”… so we get this dystopian landscape of WiFi for any high-density area.

IMO, new builds don’t really have an excuse not to, it’s a trivial additional cost to install while things are being built, putting AP hookups in the ceilings, and WiFi blocking measures in the walls between units, but they still don’t, because cost. They want to spend nothing and collect huge rent payments for basically squatting on a plot of land.

Also WiFi is half duplex so you only get those speeds in one direction at a time.

I have a 10 meter cat5 cable I use for one application that can’t have any interruptions or lag.

Calling it cat5 cable makes any woman who hears me want to leave their man for me. Good to see another king our there using the proper terminology, stay tight player

Physical limit for 2.4GHz is 1.11 gigabits per second or only 143 megabytes per second AT ALL. For 5GHz it’s slightly more than twice as much, but still less than even shitty cat5e, that allows 2.5GBE at 100 meters or in certain conditions 5GBE.

While with cat6 you’ll probably do 2.5gbps to 100m no problem,

Cat6 is 5gbps no problem at 100 meters and 10gbps at 55 meters.

I remember running out of those at work, & intentionally crushing the cheap-ass crimp-tool in my hand, just so I could finish up the next day with pass-through connectors & my Klein tool, rather than spend the next two hours re-terminating connectors that I ‘should have’ gotten exactly right the first time.

Replacing connectors is east, but won’t solve your problem if the issue is bad cables in the walls. Pulling new cables entirely depends on how well they were installed. A lazy install will actually be much easier to replace, because a lazy installer won’t bother stapling cables in place. They’ll just run the cables across the attic/crawl space and leave it where it lands.

If you’re lucky and got a lazy installer, then you can be equally lazy; The old cable in the wall is going to be your pull line for your new cable. Step 1 is figuring out which lines are which. This is easier with something like a cable sniffer, but there are a few ways to do it. But assuming you know which cables are which, the rest is fairly straightforward.

Use electrical tape to affix the old cable to the new one. Just make a bend on each cable, hook the resulting bends together, then wrap them tightly with electrical tape. The bends hooked together allow the cable to hold the strain, rather than the adhesive on the tape. And you want to use electrical tape because it stretches. Pulling it tight when you wrap ensures that the tape will compress the cables with every wrap. You also want to try to make the connection as “smooth” as possible, so it won’t snag on anything when you pull it.

Now that the old cable is attached to the new, just grab the other end of the old cable and start pulling. It’ll drag the new cable through the wall for you as you pull it out of the wall. Fair warning this is much easier if you have someone feeding the new cable in as you pull, to ensure it doesn’t snag on anything as it enters the wall. It also only reliably works on installs without a lot of bends and corners; Every corner you have to pull around is another potential corner to get snagged on. If you get snagged, sometimes pulling it backwards (tugging on the new cable entering the wall) can help you reset to try again. But sometimes there’s no replacement for good old fashioned legwork; If you get really stuck, or your tape comes undone, or your cable breaks from the strain, you may need to go crawling around your attic to fix it. This is a fast method, but it’s not 100% reliable.

No pulling wires from walls, just cutting the ends off and installing new connectors. Might not be enough in every case though.

Crimping took me like 5 attempts to get right when I learned it in school.

Pedantic but correct. Only your connection to the internet is down.

Even when there are massive “internet outages” sometimes it’s just DNS being bad. The internet works just fine, it’s just not working in a way that you can make use of it.

I think people care about different things, networking might not be something they’re interested in so aren’t interested in spending time learning about it. Where as when you are interested in it it’s not so hard to read, watch videos about it and experiment with it. At least that’s generally how I find these things work.

I run a 20m from my landline Box to my Router. In the hallway I route it behind the furniture. On doors I router it along the frame with transparent Self-adhesive cable older I got of Amazon.

You’d be surprised.

What about lan to wan? Can it detect that too?

ethernet loop detection isn’t as common as you think.

Network storm protection built in? Pretty fancy

Didn’t know this was a thing. Tytyty

Those are the way.

I bought a bulk bag of the shitty kind. Worst purchase of my life. I was too stubborn to throw them out and it took a decade+ to get through them all.

Ehhh… not quite. There’s evidence that copper runs closer to the speed of light (aka c), than fiber. Light through glass runs at around 2/3 c, making it the slowest option.

Wireless technically runs as fast as light, through atmosphere that’s a tiny bit slower than c, but as close as we can get.

There’s also a large argument among physisicts and electrician YouTubers about the speed of electricity through a wire, and I don’t understand the conclusions, though they were articulated quite well by the YouTubers, it just didn’t stick in my brain. The premise is how fast a lightbulb would illuminate if it had one light-second of pure copper (or superconducting) wire between the power source and the bulb, with little to no resistance. It’s interesting but nuanced and complex.

Wifi, being EM waves (same as light) should run the fastest, copper ethernet close behind and fiber dragging it’s heels at 2/3rds c. However, in practical applications, wifi has more to overcome since it’s a shared medium. Copper and fiber have a dedicated medium, so they have no competition in signaling, wifi needs to contend with everything from other wifi networks spurious emissions from other frequencies, even background cosmic radiation, as well as itself (half duplex). Because of all of that, you generally end up with wifi in last because it has so many protections and checks that it delays itself to ensure that it’s transmission will be recieved intact. The packets are generally larger and take longer to get started, so all the additional (mostly artificial) slowdowns make it slower. However, if you use highly directional antennas, a pair of them, on different but otherwise equivalent frequencies for send/receive, and cut out a lot of the other factors by designing the system well, then disable most of the protections because they’re not needed by design, it will be faster, at least in terms of latency, than fiber or copper in almost every case.

Since designing a multi-access system that doesn’t need wifi’s protections is borderline impossible, this is limited to very controlled point to point systems where both ends are tightly constrained.

So the argument “wifi has a lower minimum latency” is correct, but irrelevant in 99.99% of use-cases. Copper is easier and cheaper than fiber and actually runs faster, than fiber, but it’s only viable for extremely short runs, up to 100m in most cases, and fiber, while “slow” at 2/3rds c, is better for longer distance since there’s less line-loss across the glass per foot.

This is a very deep topic and I’m no physicist, but I’ve been endlessly fascinated by this issue for a very long time. The information here is the result of my research over many years. I still consider fiber to be the gold standard of data communication, ethernet to be next-best and overall best for relatively short connections, and wireless to be dead last due to all the challenges it faces that are not easily overcome.

Is the notebook or desktop wifi NIC and antenna important or only the router? Because when I had a shitty laptop a few years back the latency sucked ass, both at home and at my university (where I hope they had good network components but idk)

Unless you have no choice - a good WiFi will not add noticeable latency.

Myself I am playing over 5ghz wifi. I would say I don’t feel much difference, but prefer cable any time!

I just tested ping between my weak computers, one of which supports only 100mbit ethernet and are sequentially connected via cheap 2$ dumb switch and ISP-provided router and got 0.187ms average, while ping via same system, but using 802.11ac for one device got 8.16ms with standard deviation of 11.9, maximum of 67ms and minimum of 1.44ms.

Right. Like even in the shittiest scenario that’s not a major difference. There’s stuff like interference and the speeds are lower, sure, but 1 gigabit is plenty for non enterprise situations

Maybe…

your latency on your network might be 0.6ms, but for most practical use-cases, it will be orders of magnitude more. Partly due to the interference and half duplex nature of wifi, but also because of CSMA/CA (carrier sense multi access / collision avoidance) algorithm, which listens before transmitting to ensure the channel is clear, and waits when it’s busy until it’s clear before transmitting. The actual transit time for each frame is very short, but getting to the point where you can actually transmit is the main challenge for wifi.

Propegation time for a 1500 byte frame on gigabit Ethernet is approximately 12 µs, or 12 microseconds, aka 0.012 ms. So the argument is kind of squished here. Given that you have a dedicated channel to the switch (and not needing a carrier sense, collision avoidance of detection algorithm with ethernet) the frame can be immediately sent, so the total transit time from a computer connected by ethernet to a router or switch is orders of magnitude faster.
