I'm sorry who is using RJ45 ports on a laptop these days? Seems like that question was asked and answered years ago, and wifi has won.
- m4x 6y agoI use it on a regular basis to connect to industrial networks. Wireless is not typically available in that situation and for good reason.
- jdxcode 6y agoI would say I run into a situation where I dig my RJ45 dongle out of my bag once per year still. Usually if I'm in a different office or trying to fix Wifi or something. For me the dongle is annoying but probably sufficient. I've also worked in offices where the Ethernet was better because it didn't require VPN access and was more reliable, but in those situations I plugged it into my monitor rather than directly into the laptop.
- msla 6y ago> I'm sorry who is using RJ45 ports on a laptop these days? Everyone who understands collision domains. Everyone who understands bandwidth.
- imwillofficial 6y agoI don't think you understand collision domains.
- msla 6y agoI understand that a WiFi LAN is one.
- imwillofficial 6y agoEvery port on a switch is one.
- msla 6y agohttps://en.wikipedia.org/wiki/Collision_domain https://en.wikipedia.org/wiki/Collision_domain > By connecting each device directly to a port on the switch, either each port on a switch becomes its own collision domain (in the case of half-duplex links), or the possibility of collisions is eliminated entirely in the case of full-duplex links. For Gigabit Ethernet and faster, no hubs or repeaters exist and all devices require full-duplex links.
- imwillofficial 6y ago"or the possibility of collisions is eliminated entirely in the case of full-duplex links." So is a wifi connection full or half duplex? I don't think you understand collision domains.
- auxym 6y agoI've worked in many companies (both software and non-software) where ethernet was the only way to access the corporate network. One had WiFi that only gave internet access, the other had no WiFi at all (in 2017).
- km3r 6y agoI use mine nowadays, because my room is just far enough from the access point for occasion zoom drops. The 'better' solution would have probably been to put an access point right in my room, but I already have an RJ45 dongle + ethernet cord and I trust a cable connection to have less drops than wifi.
- liotier 6y agoWelcome to dense urban environments, where the list of available wi-fi networks is well above fifty and the throughput well under 100 Mb/s on a good day... When I sit at my desk, I plug the RJ-45 and I get 1 Gb/s - no ifs, no buts !
- NikolaNovak 6y agoYo (hand up). I mean. Really. That strikes me as willfully ignorant and arrogant. Clearly it's heavily used, especially in professional/corporate environments. FWIW I use WiFi if I have to on the move. But at home and office it's hard wire all the way. In the office it's not even an option, everybody must. At home, it's a quality of life thing. The speed drops and disconnections and unpredictability of WiFi are not thing of the past yet. For some there's a security issue as well, real or perceived. Wire just works. Edit: other examples - gaming laptops; secure networks; dense environments either urban or corporate; anything that needs predictable connectivity, bandwidth and lag really :-/
- adrian_b 6y agoExactly the same applies to me. Both my own laptop and the laptop from my employer (a large company) are used almost all the time on wired Ethernet, the main exception being during business trips.
- imwillofficial 6y ago"Clearly it's heavily used, especially in professional/corporate environments." It's so clear that they removed it from their lineup? Clearly you're wrong. I have two Macbooks work/home, and a USB-C dock has been life changing in its awesomeness. And yes my dock has RJ-45 ;)
- ben-schaaf 6y ago> It's so clear that they removed it from their lineup? Clearly you're wrong. They also removed scissor switches, sd card readers and hdmi. But they're bringing those back (or have already), so they don't seem like a good authority to appeal to here.
- imwillofficial 6y agoHave they? Their newest laptops are USB-C only.
- fomine3 6y ago
- robotnikman 6y agoAt work when at my desk. If every device in the office were on Wifi, things would be a mess
- imwillofficial 6y agoUSB-C Dock solved this problem for me.
- funcDropShadow 6y agoHands up. My laptop is sitting at home 1,5 m away from my Unifi access point and the network cable is still measurably more reliable and performant. Wifi might have won the amateurs.
- webmobdev 6y agoCome on, that's ridiculous - wired LAN is more secure and faster than Wifi - anywhere I go, I prefer wired to Wifi.
- NovaS1X 6y agoEvery single one of our laptops gets sent out with an accompanying Ethernet dongle. Every one. Still very much useful in corporate environments.
- t0astbread 6y agoApart from what everyone else was already saying I have another cool use case: When transferring large files between two devices it's neat to be able to establish a point-to-point Ethernet connection between them, configure static IP addresses and netcat the files over it. It's fast, I don't need to encrypt anything and I'm not hogging anyone's bandwidth.
- anonu 6y agoDepends on who your audience is. HN crowd: give them an RJ45.
