Does this ridiculous number of antennas even do anything or is it just marketing wank?
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.
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.
Lookup “phased array” and “beam forming”
Lord Sauron would like a word.
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.
To be more precise it’s not each stream having it’s own antenna, you combine the signals from all antennas and then “spatially filter” it into separate streams, but the number of concurrent streams is limited by the minimum of the number of antennas at both ends of the connection, if your device has only one antenna and your access point has eight you can only have one data stream.
What fast of a WAN connection are you talking about?
I can’t see how a midrange 802.11AC AP could suffice for a decent WAN connection. IMO you need at least 802.11ax
2x2 AC on 5ghz has an 867mbps max PHY throughput, which after a 50% derate for signal quality and overhead is still a very comfortable 400mbps… typical cable internet is around 100 to 500mbps with a lot of places offering “1gbps” that it never actually reaches, so it’s certainly sufficient for 90% of people.
If you have a very heavy multi user (6+ devices always on) household you may find some benefit from an AX 2x2 or 3x3 router just because it can handle congestion better.
Six plus always-on devices is rookie numbers. I’m in the twenties, in a house with a handful of people.
And yes, the router I’m currently using is faster than all my wired devices over wifi, save for the two that pair some form of 2.5/10Gb ports. Also yes, my 1Gbps WAN hits about 900-ish on the downstream, with the ISP guaranteeing at least 800 as a legal requirement. I don’t know if other regions allow ISPs to sell connections that run at 50% of the advertised speed, but… yeah, no, that’s illegal here.
Honestly, full home coverage is the biggest issue I have. If this was a new house I would have wired it as a solution, but as it is, I only got the whole home fully connected with reliable speeds by spending a bunch of money in wireless networking gear.
Well since the ruler’s out, 133 here. It’s hell.
Explanation: mostly younger roommates. Majority of bandwidth goes to just 21 personal machines, 4 MLO devices in particular, 1 of which uploads a fuck ton of cam stuff.
That said, most connections are idle. In particular there’s a chunky subnet of energy monitors with a low hum of usage.
I say “hell” because it takes 7 mesh nodes to reach everyone (while playing nice re: antenna strength in a congested building), maintaining security and privacy for everyone requires planning, and the second anything goes wrong everyone loses their minds.
Woof, yeah, now you’re talking.
I mean, once you factor in a phone, a computer, probably some gaming device running updates in the background, you’re thinking at least three devices per person, plus whatever tablets, smart TVs, printers and IoT garbage you have lying around the house. And if you live on an apartment you’re trying to service all of that alongside a bunch of other people trying to do the same.
Honestly, I struggled a lot to get a solid, cost effective mesh to solve the issue. I ended up going back to brute forcing it with a chonker of a router. No idea if that impacts my neighbours and, frankly, at this point it’s every bubble of electromagnetic real estate for themselves.
It’s honestly crazy how much networking you have to do at home these days, particularly if you work from home or throw in a NAS into the mix. I have no idea how the normies manage. Maybe they pay somebody to set it up?
I’ve wondered the same. Pretty sure they just lean on the ISP equipment offerings and outsource the rest to the cloud. Critically, I envision plug and play users who don’t give a shit about security or privacy, and that simplifies a lot.
Honestly if you take that setup from the ISP (which I think is often free and now usually includes a docsis 3.x with at least one repeater, installed) then just bump the default encryption and add a VPN, I wouldn’t say it’s a bad way to go at all, mainly because when there’s any issue it’s on the ISP to fix it.
It won’t be bleeding edge and you won’t be able to do any directed networking fanciness without your own gear, but the not my problem perk is nothing to sneeze at.
And yeah mesh is a headache. It’s all wired backhaul (sfp+ and copper) but nodes regularly fall out of sync and the mesh doesn’t heal properly. Main reason I kept coming back was the benefit of co-channel stacking, which makes your signal footprint small but really deep so neighboring routers move over.
Yeah the meme is just trying to be superior edgy. We live in an old duplex and no, my landlord won’t let me run networking through the walls and ceiling. I tried cabled network over electricity sockets and it’s worse than a good wireless connection.
It’s not all about the WAN speed. Having fast LAN speeds is always worth it.
This will help hugely with stuff like PC game streaming (from your PC to a tablet or TV for example), screen sharing to TV, file transfers over LAN, media servers, etc.
You won’t ever get anywhere close to that though on 2x2 AC.
Where do you live where 1 Gbit/s is much lower than 1 GBit/s? When I had 1 GBit/s, I got around 800-950 Mbit/s. When I had 2 Gbit/s I got around 1,7-2,5 Gbit/s
What do you define as a “decent” WAN connection?
Great answer. Thank you
I’m a network professional with a specialty in wireless.
Yeah, beam forming and mimo are the main reasons for antenna diversity. There’s also more radio chains in those units typically, and more radio chains can provide better speeds if you have client devices that can take advantage of the extra radio chains (both sides need to have the same, increased number of radio chains to see an increase).
The antennas are fairly small/thin pieces of wire that are not very long, so the antennas don’t need to look like that, but the quantity is useful.
As someone with a telecommunications background who’s taken apart some cheap routers that look like that: the only caveat I’ll add is that the antennas are only useful if they’re actually connected to anything. From a decently trustworthy brand you’re probably fine, but I’ve seen a few where only one or two of the antenna couplings were connected to anything internally.
There’s no shortage of liars and cheats everywhere. I’m unsurprised that a company world either intentionally, or through sheer ignorance, have “antennas” that are little more than aesthetic pieces of plastic.
I believe it’s for beam forming which can be used to improve signal strength in a specific direction.
Some of them are marketing wank, some of them have MIMO channels that need multiple antennas to support independent bands with multiple devices.
1 MIMO channel = 2 antennas, so this router could theoretically have 4 devices communicating bilaterally without interrupting each other.
tell that to the $800 of copper running through my walls.
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’re
Still cheaper
*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
And the contractor to do it all.
Why wouldn’t you do it yourself?
Like, in an old house its a massive pain in the ass to run that, but still firmly in DIY territory.
Disabled, so physically cannot do it, or I would.
And then you still need a wireless router to get Internet on your phone unless you use data at home like a crazy person.
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?
If that happens often enough to be worth 43 times more than the cat cable, then it sounds totally justified to me. But also, what if you got a toaster oven for upstairs? To put next to the router?
What if you used the router as the toaster oven? Tapping_head.gif
My PC, laptop, work laptop, are all wired using gigabit. But my laptop on wifi reach 1200Mbps so it’s faster than cable!
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.
Impressive, I lose half my speed with the router around the corner.
If you have only one device on Wi-Fi, multiplexing turned off, or especially if you have MU-MIMO support, Wi-Fi can be faster than a single wired connection. It is still higher latency and subject to other drawbacks such as security and power consumption, but of course it offers advantages that can outweigh the disadvantages depending on use case and user needs.
That said, it’s technically not faster than the cable, but rather faster at the data link or network layer. For example, CAT8 physically supports up to 40Gbps, but most consumer and even professional electronics only support up to 2.5Gbps. Only really enterprise level switches can push up to like 100Gbps onto copper, and even then that’s using QSFP transceivers, not RJ-45 connections. Fiber cables regularly push 400Gbps.
Same lol. I get 800Mbps on Cat6, but 1100 on Wifi 6 with one of these fancy expensive 11000ax gaming routers that has all those antennas (antennae?).
Ethernet is obviously better but running ethernet around your home can be a pain in the arse
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.
I think it’s a little more than $500 to get Ethernet ports installed all around your house. Especially if you need to run through fire breaks and insulation. Will have to wait till a remodel before I can get those installed.
That said, I didn’t skimp on my home networking, even though it’s all wireless. I’ve got 4 WiFi 6 APs on PoE with Cat 6 runs thru the attic. I can get 700 Mbs+ download speeds pretty much anywhere in and around the house.
It could be, depending on where you land on the DIY vs building code spectrum… Also what your local building code details in terms of low voltage cable.
In my experience unless you’re intentionally going through air handling ductwork, CMG is fine, though I would go with CMR at least, just as a matter of safety. I have yet to see a residential home with any fire protection or fire breaks, at all, nevermind where you would think to put them, like between floors and whatnot. The homes in my area are mostly built from timber, so we’re basically living inside a framework of dried out wood, so putting a fire break between wood framed floors where the floor/ceiling shares a set of wooden cross members for support, seems like it would be unnecessary, since the framing of the building is going to conduct the fire between levels.
Ethernet is low voltage, so it’s largely unregulated. The only real regulation is regarding plenum or riser spaces, and the latter is mostly when floors are intentionally or naturally separated in terms of shared fate when it comes to fire. I only see fire breaks in concrete structures, usually apartments or commercial buildings.
YMMV, not every country has the same building codes, so every person reading this will need to do their own research or pay someone who knows.
My point remains, regardless of all this conjecture: even if it’s $2000 or more, this is structure cabling that should service the premise for as long as it continues to stand, which is hopefully many decades. Over 20 years, at $2000 for installation, you’re looking at a cost of around $8.34/mo for the cabling to exist.
Considering people will pay 10x that for Internet service, and the addition of Ethernet in the building will allow them to take full advantage of the internet they’re paying for, I’d call that a bargain.
Preach! I just finished a long DIY remodel and running ethernet to everyroom was less than a $100 in cable and connectors. Obviously it was easier and cheaper for me because I already had a lot of the drywall down.
Either way such a good point you make, people will drop 1k on a phone no questions asked but a few hundred is too much to get the best home upgrade a tech enthusiast could ever ask for.
I could preach all day about this.
I have a simple philosophy: wired when you can, wireless when you have to.
With that being said, doing a site survey for wifi and getting optimal access point locations, then placing Ethernet in ceiling there for said access points, ensures you have good coverage of your space, which then leads into another rant about network hardware and people spending thousands on everything except their router/access points even if they have the structure cables to support such a system…
Then people wonder why their wifi sucks.
I mean, spend a couple hundred one time to get Ethernet run, spend some time on an online ap placement tool and signal estimator for it, and then go buy infrastructure wireless for your home, and spend upwards of $1000 on networking hardware. You’ll get more out of it and it will work for longer than your $1000+ smart phone, or many $1000s laptop that use it almost constantly.
Networking is critical and it should be seamless and blend into the background. You shouldn’t need to mess with it constantly to get it to work. If that’s normal for you, then something is very wrong.
So far, I’m only £150 down on cable and clips on my rennovation. And this is the decent stuff, AWG23, and double run.
It’ll probably go sideways when I spec up a switch with enough ports, mind…
Or if you rent. I could run an Ethernet cable to my office from my router, but it would have to run upstairs and across a few doorways.
Way less so if your home is constructed such that the wireless is borked
Let’s see that ethernet cable do orthogonal frequency-division multiplexing…
Dude I just bought 4 refurbished Linksys MX4200 (tri-band) access points for $80 (total), put on OpenWRT, and built a mesh system. I’m incredibly happy with the result, especially for the price. And, I’ve got wireless bridges all through the house so I can keep some things off the forwarding channels and only in the back haul.
It’s not wired, but it’s close enough and doesn’t require me drilling through all my walls running cable or carving out a space in the house for all of it to coalesce.
Granted, I’m in an area with not a lot of wireless interference…I work in enterprise networking and I’ve had a lot of issues with remote workers on wireless networks that weren’t capable of handling the volume of data that the users were uploading. Sometimes just because there’s too much interference…but a lot of the time it’s because of misconfiguration (either out of ignorance or because the good features, like multicast-to-unicast, are missing), or printer drivers that spam the wireless with multicast whenever the printer is offline (which I’ve seen a surprising amount of times).
If you’re on wireless…multicast is bad, mmmkay? Only “one” device can talk at a time on wireless (barring MIMO shenanigans), and when it’s multicast traffic…it has to get sent at the lowest compatible rates. A lot of routers set this to 6Mbps or even 1Mbps by default. So your nice fancy “1200Mbps” wireless has to slow down a crawl every time your Roku wants to tell Alexa that it’s there. Which is surprisingly often. Scale up for all the internet-of-crap stuff people have and it’s a miracle their wireless works at all.
Oh and I’ve found people with extenders they don’t know about. Ring Chime? Apparently it functions as an 802.11n (only) extender. Huge bottleneck right there. And then it can only be as good as the signal it gets from the next access point.
I’m a nice fellow who provides free internet to all of my neighbors.
It’s a pain sometimes.
I worry about the teenager upstairs, but all the others are old ladies and it doesn’t bother me a bit…until I want to do something serious.
I’m about to (tax time) invest in a router that allows me to control their bandwidth. It’s free, so if 20mbps don’t work for them they can pay for it.
I will open up the kid’s PS5 so he can game. His laptop is getting 10mbps though.
Old ladies rocking 4k to sleep is too much.
They don’t pay for internet so they get the good good on their services. I’m too sorry and antisocial to go deal with it.
Legit would’ve commit crimes for 20mbps growing up. And I was one of the lucky ones too
Wireless data links should be the exclusive domain of temporary, nomadic and/or sacrificial applications.
If the channel is permanent, static, or critical; as much of the path as practicable should be provisioned with constrained energy transmission.
Would be cool if building code standards included Cat5 (or even better, USB) along with the standard power and phone connections of new builds.
I’m seriously thinking of getting a usbC-ethernet dongle for my mobile, for when I’m at my desk.
I, too, have shitty wireless. In fact, for my work laptop, that’s exactly what I do. So much more reliable. Way too many wireless connections on too many channels close by.
If you have wireless charging then you should definitely get the dongle. I have one for those times I need stability. Get a thin lightweight USB C extender so the dongle is not getting in the way.
Getting a USB dock instead would probably get you both charging and Ethernet.
I have one that has hdmi and usb as well so I can use my phone in desktop mode on a monitor, then I use parsec to get in my VM and I have access to a full desktop experience
Nice!
For others considering this, keep in mind that not all phones support external monitors, they need specific hardware for it. Pretty much all Samsung S phones support it, Pixels do not. So check if your phone supports external displays before you buy any hardware!
Google added external monitor support starting with the Pixel 8. So, yeah… Most don’t support it, but newer ones do!
Can you not charge and use a single USB-C port at the same time?
Yes you can. You just need a dock instead.
I mean I just have more than one port and can charge using the dedicated charging port.
What laptop are you using that makes it such an affair to use two USB-C ports?
Edit: I missed the “mobile” part
If I’m reading the thread correctly, they’re referring to a mobile phone which only has 1 USB port typically
Ah butts, you’re right, the first guy said “mobile” and I didn’t read it correctly. I can’t figure why they would ever need a connection like that for their phone, though.
Unless you need 6ft of cable or you just run wires on the floor it’s more like $200 of plenium rated cable, and keystone jacks and the labor involved with the run.
My house with a half finished basement (easy access) took probably 16-20 hours running to 5 rooms.
Yeah when i did my house i was quoted $100-200 a drop and that was years ago. I bought materials for 20 drops for about 1k (cables, keystones, plates, cable tester, ethernet cutter, puncher, drywall knife, flex drill bit, wall fishing tape, network switch, and a bunch of other stuff im probably forgetting). It took me 1 hour per drop on average. Some were easy, some were a pain in the ass. Now you can save on materials slightly by doing 1 drop per room whereas i did individual drops for each jack (because i wanted full bandwidth on each line), but either way it is going to end up more costly than an access point or mesh system unless you’re just running one line within the same room.
Definitely worth it if you care about the speed or reliability of your connection but i think for most people these days it’s probably overkill.
If you do go wiring everything then now you’re mostly already set up to do some Power-over-Ethernet (PoE) devices for cameras, access points etc. And next thing you know you’re an amateur home networker!
I got a used 10Gbe switch and a thunderbolt 10Gbe adapter for my computer and now I can transfer my videos and photos from my NAS like it’s my internal hard drives.
It can also do 2.5Gbe which pretty much future proofs me.
6.99 is just one cost though. If you’re needing ethernet actually done in walls then you’re going to be paying a lot more than an access point.
I have about 6 or 8 ethernet cables in use plus more in my spare cables box, and I don’t remember ever paying for one. Where do they come from? I never seem to run out.
But that cable can’t summon Kel’Tuzad unlike the router.
