Does this ridiculous number of antennas even do anything or is it just marketing wank?

[-] themoonisacheese@sh.itjust.works 120 points 4 days ago

Technically, it does provide better connection speeds by enabling the router to avoid channel hopping, so it can talk to multiple devices (or the same devices if it has multiple antennae) at the same time. This is part of the recent wifi6 and wifi7 standards so more and more devices will start to gain speeds using this technique

Realistically computers have at best 2 antennae and this is largely marketing wank.

[-] Soup@lemmy.world 42 points 4 days ago

Though if you have multiple devices all trying to connect to wifi, like even a phone for example, then a computer having two antenna that it can actually use 100% of the time still sounds valuable to me.

It does. Wifi uses MIMO (Multi-in, multi-out) to run multiple concurrent data streams over the same channel width, which overcomes individual channel bandwidth limitations (there's only so much radio frequency space to go around). Each stream having its own antenna, and having larger antennas, gives stronger signal/noise ratios, less retransmitted packets, and overall better connections.

A lot of those high end "gaming" routers are often oversold though.... MIMO improves throughput if you have an Internet link it can saturate; realistically even a midrange 2x2 802.11AC router will provide more wifi bandwidth than your internet does. And for gaming, they do nothing to improve latency no matter how many streams you run, as wifi's inherent delay (5-15ms) is pretty much a fixed quantity due to its radio broadcast time-sharing nature. The meme is correct. A $6 ethernet cable beats any and all wifi routers and client adapters, and always will.

Wireless tech has improved greatly over the last 20 years. Speed, latency, bandwidth, stability…all generally excellent. 15 years ago I wouldn’t have wanted to use a wireless mouse or LAN connection. Now? NBD. They just work. Still have issues with poor signal in some areas, but mesh range boosters take care of that pretty easily.

Wireless peripheral devices, sure, but if I'm streaming 4K with HD sound then I still want copper.

tell that to the $800 of copper running through my walls.

[-] stupidcasey@lemmy.world 54 points 4 days ago

Hay $800 worth of copper, I found a 1000ft roll of shielded pure copper for $2.11 because someone misplaced the decimal point I know because it was listed for $2.1199 every thing was automated through amazon so they just shipped free shipping to, thank for listening $800 worth of copper, your the best.

You could have 30 clips break and it would still be cheaper.

But what if you're gaming downstairs and the router is upstairs and then you have to go upstairs for pizza rolls so you take your gaming laptop upstairs and you're eating right next to the router and so you're just plugged in and then what if you forgot to turn off the oven and your girlfriend is yelling at you "You're going to start a fire! Why can't you remember to turn off the oven? What's wrong with you?" and then you go back downstairs to finish gaming?

Nah, wifi is pretty good today. I just dont like the consumer devices like the router shown here. Recently redid my wireless and went with a non wifi router, a poe switch and a few access points, connected through ethernet. I wouldnt dream of going back to the conventional one wifi router. Still use wired for stationary devices I can reach with a cable though.. TV, AV, consoles, PC are all wired.

[-] TankovayaDiviziya@lemmy.world 2 points 2 days ago* (last edited 2 days ago)

To be honest, I think a lot of Lemmy users are old and yearn for the older technologies simply because they have been more familiar with them than newer ones. They would have used the first gen of a technology, which may not be efficient, and dismiss it altogether, without realising that subsequent generations of that technology improves over time.

I have had that realisation of cognitive bias when I had Bluetooth headphones back in early 2010s. The wireless connection isn't great and gets cut off every now and then. I dismissed the technology as less efficient than wired earphones. It was over the years with the popularity of airpods that I gave wireless earphones another chance. And honestly, the Bluetooth connectivity vastly improved than I expected and I would not go back to using wired earphones again on regular basis because I don't have to deal with the wires getting tangled or yanked. I only use wired ones as backup if my wireless earphones went missing or broke.

Sorry to say this to OP, but it seems that you're being an old man yelling at the clouds. Look, I'm also old and I admit I have had that moment of yelling at the clouds too. We will have that more moments as we age.

[-] anamethatisnt@lemmy.world 4 points 2 days ago

I have a similar setup to @PieMePlenty@lemmy.world in regards to my home network and I wouldn't dream of removing my wifi network. I still consider wired to be superior though it rarely matters at those latencies.

My Windows laptop on wifi:

My Fedora on wired network:

[-] LavenderDay3544@lemmy.world 3 points 2 days ago* (last edited 2 days ago)

Wifi 7 is insanely fast to the point where it can easily be just as good as wired ethernet and can even beat a lot of the wired standards except the few latest ones. It's a good choice for devices where running a cable wouldn't be very practical, but you need wired level speed and reliability.

[-] anamethatisnt@lemmy.world 9 points 2 days ago

wired level speed and ~~reliability.~~

While WiFi is a lot better nowadays I've never seen it reach the reliability of wired networks.

[-] MellowYellow13@lemmy.world 4 points 2 days ago

wired will always be better, faster, more reliable, and cheaper

[-] jim3692@discuss.online 4 points 2 days ago

I remember watching a video from Linus demonstrating a WiFi router. I don't remember if it was WiFi 6 or 7, but any obstacle could cause connection drops.

I don't know if things have improved since then, but I usually bond WiFi and PowerLine for rooms that Ethernet cannot reach.

[-] wreckedcarzz@lemmy.world 33 points 4 days ago

*Excluding running ethernet cables to every room through the attic, down the walls to wall jacks. Also the cost of the jacks, and the various switches needed for several rooms. And the contractor to do it all.

But hey for like $600 I have cat6a in basically every room so

[-] ILikeBoobies@lemmy.ca 21 points 4 days ago

And the contractor to do it all.

Why wouldn’t you do it yourself?

[-] wreckedcarzz@lemmy.world 16 points 3 days ago

Disabled, so physically cannot do it, or I would.

[-] maniclucky@lemmy.world 18 points 4 days ago

Like, in an old house its a massive pain in the ass to run that, but still firmly in DIY territory.

Ethernet is obviously better but running ethernet around your home can be a pain in the arse

[-] MystikIncarnate@lemmy.ca 16 points 4 days ago

A pain in the arse you only need to do once, and you can hire someone to do it for you for basically the same cost as a couple of the high end wireless routers, so in like 5 years, you break even.

Also, how much have you spent on your computer (s), phone(s), tablet(s), and all your other internet connected devices, and you won't spend like $500 on something that can run all that stuff simultaneously? Pouring literally thousands of dollars on connected devices, but most won't pay more than they would for a toaster, to get them on the internet, then pay out the wahzoo for gigabit internet that your crummy d-link router can't handle, and you wonder why all your fancy gadgets run like shit.... It's a lot like buying a Ferrari to drive on dirt/gravel roads.

My PC, laptop, work laptop, are all wired using gigabit. But my laptop on wifi reach 1200Mbps so it's faster than cable!

[-] nickhammes@lemmy.world 25 points 4 days ago

Faster than gigabit, but not 2.5 gigabit. Your cables likely support the speed, just your ports and switching hardware are capped at gigabit.

It's not extremely expensive, but unless you move around a lot of big files, you're probably getting very diminished returns, even spending less than twice as much for 2.5x speeds.

[-] latesleeper@lemmy.world 20 points 4 days ago

Impressive, I lose half my speed with the router around the corner.

[-] Gestrid@lemmy.ca 2 points 2 days ago

Given the choice, I'd definitely choose a cable for anything I know will require high internet usage. Wireless is just too slow, even on a 5G connection.

I still remember I once broke my Windows installation (young me had tried dual-booting the Windows 10 beta and my Windows 7 installation). I had to get system restored discs from the manufacturer. It wasn't particularly tricky to fix, but it took a long time to download those Windows updates after it finished. I noticed an immediate change once I remembered I had an old 30 ft. ethernet cable lying around and plugged it in. (This was maybe 8-10 years ago.)
