      Given how difficult it is for me to troubleshoot a network issue on WiFi, I'll stick to the simplicity, stability, reliability, & useability of a wired connection.

      Besides, the gremlins that like to screw up a WiFi connection get annoyed when they realize I don't have any, then sniff that my neighbors do, & scamper off to go screw with the neighbors instead.

        How to connect with an ethernet cable:

        1) Connect cable to device and then to a switch or router.

        2) Enjoy.

        How to connect with WiFi:

        1) Find wireless access point or router.

        2) Make sure signal is strong enough.

        3) Walk to access point and push WPS button.

        4) Walk back to device.

        5) Enter password anyway because the WPS button didn't work for some reason.

        6) Re-enter password because your fat fingers messed up.

        7) Enjoy.

          I fear that Sir might have missed some steps in the wifi connection procedure. Sir has neglected to mention the need for foul and abusive language :)

          I remember when I got Sky Q installed. The 'engineer' wanted to use wifi. I told him there was an ethernet cable ready and waiting but he said it would be easier to use wifi. So he asked me where my router was. I said it was upstairs but it wasn't a Sky router and anyway the wifi was disabled. I told him I use a wireless access point downstairs because it's a better signal for my laptop.

          At that point he decided to try the ethernet cable and "see if it works". He plugged it in, checked the box and was astonished to find that it had obtained an IP address and was all ready to go.

          After that he left. Sad to think that he probably still believes that it's easier and more reliable to connect a Sky Q box via wifi than ethernet. Hence the need for quotes around engineer :)

        From the article: allowing data to flow seamlessly even if there is interference or congestion on some of the bands.

        even in a neighborhood of single-family dwellings, there is considerable interference from AP devices on adjacent channels, etc.. Doing the multi-band multi-channel bonding thing is ONLY going to make YOUR router fast, at the expense of EVERYONE NEAR YOU. Or what would happen when EVERYBODY does this and streams high bandwidth content at the same time... ?

          All that happens is that over time a new system comes out that gives us more bandwidth - and that bandwidth gets eaten up by an increase in competing devices. Sooner or later we'll start seeing problems with 5.8G like some of us recall with 2.4G.

          Many years ago I was sent to visit a bosses friend in Monaco - hard life, someone's got to do it :-) When I looked at the wifi in use around his apartment, the list of APs was pages long - and this was when 5.8G gear was few and far between.

          And also many years ago, I recall reading a comment from someone in Korea. His problem was a UI one - there were so many WiFi SSIDs that by the time he'd scrolled down to find his - the UI refreshed the list and he had to start again !

          I'll take a wired connection any day for a static device. And not only does the ethernet cable reliably deliver the network without interference from the neighbours - it can also deliver power for some of my devices.

      Re: You can pry the ethernet cable out of my cold dead hands!

      The other thing is, Ethernet goes between floors here at full speed (cables between the cellar, ground floor and first floor), Wi-Fi struggles to achieve 10% of its theoretical speed.

      I have Unifi APs in the house and they were originally in a wireless mesh, but the floors here are all re-enforced concrete, which means the signals are a bit iffy at the best of times. The router is in the cellar and everything upstairs was getting, maybe, 1mbps from the repeater in the hall, but the signal quality 3M away, but upstairs, was around 1 - 2 bars. Throw in the waterbed and ordering new Kindle books at bed time was a challenge.

      Putting a repeater upstairs helped, a bit, we had a solid signal all over the house, but throughput was still dire. Running gigabit Ethernet to each of the APs means full speed wireless on each floor.

          Re: You can pry the ethernet cable out of my cold dead hands!

          At one place I worked they were clearing out a room and in there was a large, grey, government surplus style metal cabinet. Inside were several racks made out of the strongest fecking square section hollow steel bars I've ever seen - very simple arrangement, front bar, back bar and joined at the far ends by crossmembers.

          I said to keep that one, and I then laid all the cables over the front bar with the end level with the next bar down, laid over the gap to the back bar then back out over the next front bar going down. It was a perfect size so that most cable lengths resulted in both connectors being at the front of the cabinet next to each other. Anything longer or shorter could be accommodated using some of the spare racks. The steel was just the right roughness that the cables never slipped sideways but could be pushed to the side if needed. The edges of the steel bars were also rounded, not sharp. It took every single cable from the half-dozen mixed boxes we had. I spent a whole day filling it up, with mains at the top, printer, VGA, coaxial, serial, scsi, other weirdness in the middle and networking of various flavours at the bottom, with space on the floor for a few plastic baskets for gender-benders and other convertors and adaptors.

          The cabinet must have been entropy proof. It worked beautifully for many years. Cables en masse can get VERY heavy, and these thick bars were rock solid. You could find the specific cable someone wanted in moments.

          I later discovered when a former employee paid a visit that it was the cabinet they used to hang the Linotype magnetic tape cassettes in. We didn't have any of the tapes left, but apparently they weighed an absolute tonne, and there was a whole library of different typefaces, one family to a cassette. Hence the incredible strength of the cabinet!

          Seems bizarre now that the entire library that was held by this bespoke metal box could easily fit ten times over on something the size of a grain of wheat now.

      This is just a hardware company trying to goad other hardware companies into putting it's stuff in the stuff they make. We won't see enough uptake to worry about it for 2 years or so.

    what's the betting that it won't offer 40Gbps if you're one room away, or you live in a crowded area, or your office is full of laptops? Even with Wifi 5 (802.11ac), the claimed "1300Mbps" only gives a throughput of about 250-500Mbps in absolutely ideal conditions.

    Anyway my gripe isn't so much that it's possibly not as fast as they say, the problem is that companies make new standards quicker than people will deploy them. Most kit is still Wifi 5, with Wifi 6 beginning to make inroads, and now they're talking about wifi 7?! I know we need progress, but releasing things slower, and when they're ready, would actually mean more uptake.

        Your both mostly right, but material penetration for 6ghz vs 5ghz bands isn't in another universe. It will be slower than LoS with the access point, but probably about as fast a room or two over as your existing setup is now.

        However, for wireless to make it close to the over hyped "why would I ever use a cable again" putting one AP in each room and using an even higher band is the way to go. Cross talk between APs and other gear on the same channel/band is one of the big reasons that 2.4 is useless in much of the modern urban hellscape. Going to the 60ghz or whatever the next spec is pushing will mean the signal won't be able to get through a cardboard box, which means that your neighbors immersive AR hentai universe won't knock the UHD feed off your TV in the middle of a game.

            FYI the Faraday cage that makes up the inside of your microwave is probably good for 40db attenuation at best. 100W may drop to 1W or 0.1W (60db) but 100mw is what a typical AP emits and so Mr. Microwave screams all over the band... even when it is perfectly safe for nearby humans.

            Also magnetrons drift around and so the affected channels are pretty wide. Radar systems need to use the outgoing signal applied to an AFC circuit to make sure they can receive the echo, as every pulse is likely to be on a different frequency within a relatively narrow range,

      WiFi often won't go through things you need it to to get to where you need it, while you can't stop it reaching everyone around you when you'd rather it didn't.

        Re: Does it go through brick walls?

        If reinforced concrete is your obstacle, then you're likely facing either a structural (load-bearing) wall or a firewall. Either way, you're basically screwed either way if "around" isn't an option.

    30Gbps sounds nice but don't you have to divide that by the number of stations thst are using it?

      Worse, collisions.

      This is a horrible idea, now devices will use 3x the channels.

      This should never have been approved, wifi frequencies are few, and shared.

        Re: shared medium

        There's an interesting thing going on between the WiFi companies and the telecomms companies.

        WiFi dwells in ISM bands, or uses other people's bands with (having to ensure they don't interfere), and is being backed into a performance corner as a result. Sure, 40Gbps, but the chances of that being delivered over useful ranges with useful numbers of client machines in useful (i.e. with another network right next door) places is remote.

        Whereas the cellular network guys get reserved bandwidth, strong network management, much more transmission power, etc. With those advantages (which come at a cost - spectrum is not free), they have the ability to substantially outperform WiFi on range, or throughput, or both. Dedicated bandwidth pays dividends.

        Which begs the question, "Do we need WiFi?". If it comes to that, "Do we need Bluetooth?". 5G has fiddled with having a WiFi-esque profile. There was even talk of 5G having a Blue-tooth, Personal-Area-Network profile too. Both a wireless LAN and a wireless PAN would be better (from a purely technical performance point of view) with dedicated bandwidth. Why have WiFi when one could have something like WiFi, but better?

        I think that, basically, it comes down to branding. People are used to Bluetooth and WiFi, and it'd be a hard sell to get something different adopted.

        We probably should do away with major network standards using free / borrowed bands and have those network functions shifted to dedicated bands. However, there's no mechanism for making that happen. Companies have the liberty to develop products that use the ISM bands (or negotiate to borrow other peoples'). There is no governmental reason to say "no" to that. Also the market will always settle on whatever is good enough to sell, which is where WiFi and Bluetooth now are. So, we're probably never going to get useful functions like a wireless LAN put into dedicated bandwidth and be properly coordinated with other networks like celluar or PAN.

        I think it's interesting to look at the price we currently pay. For music to be delivered to a set of ear buds, these days that means data transport down and up the layers of the IP network stack, with the cellular network stack getting in the way there somewhere, followed by data transport down and up the layers of the Bluetooth stack. The cost is the complexity in running 3 stacks, the software to integrate the 3 stacks, and the battery power consumed.

        Ok, from an end consumer's point of view the battery power lost is modest.

        But the faff is incredible. Having that music come out of those ear buds via a different mobile / computer means pairing, setting up, logging into the Spotify account, etc. With today's networks, there's no way that the music can be addressed directly to those ear buds by the music provider.

        There's also no way that devices can learn about other permitted devices, unless a user goes through some sort of pairing process for each and every desired combination of pairings.

        Looked at this way, it all looks woefully non-joined up. Though I'm not convinced that this is enough to force improvements through.

      No, it's worse than that. Collisions increase geometrically with the number of devices you connect.

    Wired speeds*

    * Wired speeds when you're in less than 1m away and there are no obstructions. The only advantage I see in WiFi is not tripping over a patch cable. I still need lots of Ethernet cables to keep the WiFi APs in close range.

    I don't believe any of the hype surrounding WiFi. It's radio and in the real world it is pretty appalling and unreliable.

    We recently moved into a new rented place and it has no wired networking, something that we enjoyed in our previous place.

    Not sure what the specific issue is, but wherever I put the network access point, you cannot get WiFi in half of the house, with no convenient way to wire up a repeater to the other half.

    We actually solved the problem with some of those Powerline networking plugs. For our situation, they're actually pretty sweet and we get a good reliable throughput, not Gbit mind, but good enough. Powerline from the router to a couple of remote places in the house and a Wifi repeater attached to one of them for WiFi coverage.

    1. LybsterRoy Silver badge

      Very similar solution here but needed because of foil backed plasterboard. Occasionally the line back to the router goes titsup but I discovered that unplug the cable from the laptop, wait a couple of seconds and replug and things are fine.

  12. martinusher Silver badge

    All that glitters

    I haven't followed this version of the protocol but if it follows past form then the bandwidth advertisements will be based on coding rate which is invariably wildly optimistic. To explain. The WiFi packet is made up of a string of coded symbols, a packet consisting of a preamble, some low rate information followed by the packet data proper. The result is that many packets consist of a dozen symbols for framing and housekeeping information plus a string of data symbols coded for whatever the fastest rate you can get away with. If the packet is long then you can 'lose' the overhead of the initial symbols but most packets are not, they're comparatively short, so the actual data rate of a real world transmission is usually a lot lower than the advertised coding rate. Once you add in contention -- two or more nodes competing for the same bandwidth (remember they don't even need to be on the same network) then the effective transfer rate drops even more. Much ingenuity has gone into overcoming these limitations but realistically they will never compete with a 1000BaseT link (or even 100BaseT in most real world situations). This doesn't mean this new WiFi is useless, just that marketing people have form when it comes to overstating a technolgy's performance.

    (...and yes, if its using virgin bandwidth then it will scream along. But then everyone else + dog will move in and it will be back to normal)

    40Gbps sounds amazing, but...

    I hope it uplinks to the network router or switch over something faster than 1Gbps Ethernet. Eventually there's going to be a wired Ethernet connecting the wireless access point to the backend, and 2.5Gbps/5Gbps/10Gbps ports are still not exactly commonplace (getting better, but still classed - and priced - as "premium" for some reason), even less so 40Gbps ports (maybe link aggregating multiple 10Gbps ports will work/be required).

    Feeding the 40Gbps WiFi7 beast sounds like it may be the more difficult nut to crack, in a world of predominantly 1Gbps wired connections.

      Re: 40Gbps sounds amazing, but...

      2.5 & 5 Gbps PoE needs to become popular and cheap, quickly. It's such a shame that there's an unmet need right in the middle of the market. The standards work, and they allow you to re-use a lot of existing cabling, whilst providing worthwhile performance increases.

      Where's all the gear?

      1. Richard 12 Silver badge

        Re: 40Gbps sounds amazing, but...

        There's no market for anything faster than 1Gbps but slower than "the fastest feasible"

        Datacentre needs the fastest you can give it, but home and office usage is almost always practically limited by the Internet connection, which is currently almost always in the region of 40-500Mbps, and basically never faster than 1Gbps.

        Dunno if that was solved for 10

        As they're actually fallback symbol rates of 10Gbps, why sell at 2.5Gbps when you can sell it as 10Gbps

        Power delivery adds further complexity, I know the 2-wire Ethernet standards committees are currently trying to figure out how to do that. Dunno if that's solved for 10/5/2.5Gbps though.

        So, what are you going to do with 5Gbps?

    ... I see we're recycling the claims from the .11ad days

    Seriously, wasn't this almost verbatim the promise vendors were making when trying to fling their 802.11ad-capable devices (ie 'wireless' laptop docks)? At least WiGig had the 'excuse' that it was aimed at enterprise clients still using the bulkier docks of yesteryear (as if that's a bad thing) and was kinda positioned to make a lot of the cables redundant, by allowing the user to plop his or her device out of the way in a more "efficient" * way ... in the days before USB-PD made docks little bigger than USB hubs of old... and for a fraction of the price of the bloody WiGig docks :D Too bad that after enough procurement types bought into the hype and the overpriced stock people realized that the tech was glitchier than a 20$ Ninvento in its initial form to make .11ad NIC "upgrades" unsellable on business machines :D

    *Nothing has wasted more time, effort and nerves than some moronic efficiency drive nuking "good enough"... sometimes I wonder how popular a "strangers on a train" scenario would be for dealing with the higher ups that make IT work "interesting" :D

    my whole house is wired and anything wifi is switched off. why ? so the neighbors can't bog down or leech off my network !

    That is the problem with wifi. you may have high bandwidth but there are only 11 , 15 or 16 channels in the spectrum. ( depending on where you live). I can see at least 20 different routers so some of these are 'sharing' a channel ( time multiplex) .

      I have both, wired and wireless. I like the convenience of quickly checking emails on the phone or tablet, or just sitting down in a comfy chair with the laptop to do some stuff. I prefer a wired connection for work, media delivery, file storage, basically actually everything.

      And yes, the problem is that there are too many networks for too few channels, because _all_ neighbours crank up their AP's sending level to absolute maximum. You can see the AP a few appartment blocks away. That results in about... 50 or so networks visible from here, I stopped counting - and this results in the reliability and performace that we all love about wireless.

    Even wireless needs wires. The AP still needs to have wires to it. So there are what about 25 20Mhz channels in 5Ghz? So by moving to 320Mhz bonded, that is 16 of the 25 channels. So one AP will use 2/3 of the channels. If you need to that much bandwidth, wired will still be faster since it will be full duplexed.

    Will Wifi8 be 500Mhz bonded?

    WiFi - is that thing still going? I gave up on it years ago - I'll stick with my powerline LAN, thanks, (her indoors won't let me drill holes in all the walls and drape wires everywhere for some unaccountable reason).

    As someone else has pointed out - 'new standard' = "we need to sell more kit". 5GHz wifi reliably gets about half the distance of 2.4GHz wifi in my place, or to put it another, it's twice as useless as 2.4GHz. It might be great if you've got a cardboard house, but no good if you've got brick and/or block walls..

      Re: Powerline?

      Doesn't powerline LAN have its own sniffing issues, especially in communal settings like apartment buildings?

      Anyway, I recognize that both wired and wierless Internet has its uses. Some people, for example, have to use portable devices or aren't allowed to wire up for one reason or another (usually tenant restrictions). Others, as noted, have radio-restrictive layouts.

      What I'd like to see is a solution for someone who has both at once: they can't use wireless, AND they're not allowed to wire up. Maybe worse, their power lines aren't well suited for a powerline-based setup, either.

      1. Richard 12 Silver badge

        Re: Powerline?

        Powerline is wireless over shitty waveguides.

        So yes, you are sharing bandwidth with everyone else on your phase.

        It's great as long as nobody else has it.

        What data transfer physical medium are you suggesting for a user who can't run cables, use wireless or any preexisting power cable? Magic?

        1. Charles 9

          Re: Powerline?

          I sure would like to know. My home is owned, but multi-story and old, so there's no easy way to cross floors other to run outside, making certain rooms downstairs nigh-inaccessible (no outside walls). Also because it's old, some of the walls have radio-attenuating materials (they're also load-bearing so can't be easily replaced). It creates some distinct not-spots in the house that have no easy solutions.

          Just saying there are plausible scenarios where neither solution is practical.

  21. ibmalone

    Maybe get the simple things working first?

    Had to replace a MediaTek wifi+bluetooth module in a new laptop as the bluetooth LE mouse would get lost and require complete repairing whenever it was idle for a couple of minutes, or the machine went to sleep, or you restarted the computer. Both windows and linux, so likely a firmware or hardware issue that I haven't had with Broadcom or Intel. So maybe they should figure out how to handle devices going into standby on 12 year-old standards before trying to sell us on implementations of draft standards.

    Anyway, the idea that 40Gbps will replace the 10GbE and vlans holding our server room together seems a little optimistic, not to mention nightmarish.

    I'll be happy when I can pick a random AP, a random WiFi device, turn them on, enter the correct password, open a web page, and actually get it most of the time.

    As opposed to the current situation, where most of the times, even when the AP is in LoS 30cm away, the connection stalls for thirty seconds and then fails giving no reason; or proudly shows five bars out of five, but does not actually even resolve URLs; or oscillates randomly between the nominal speed and the speed of a typewriter; or works but drops randomly every few minutes; and so on and so forth.

    "Throw away your Ethernet cables* because MediaTek says Wi-Fi 7 will replace them"

    Bullshit bullshit bullshit.

    Don't get me wrong, WiFi has its uses. But fundamentally it still solves one, and ONLY one problem - NOT being able to use a cable.

    In every other way it is nothing but problems compared to a cable.

    How many WiFi channels do you need to get the same throughput as a good wired network with proper distribution type switching fabric?

    Then there is security - doesn't matter how much encryption you use, with WiFi you are still broadcasting your data. Anyone can (potentially) listen to it and grab it.

    At one of my sites one of my access points can see 40+ other WiFi NETWORKS!!!! None of which are ours.

    The higher the data rate with radio, the more subsceptible it is to anything - building layout and construction, furniture, even people walking around. That is just the way radio is.

    And it is awful lot of (complex) technology just to try and replace a length of copper.
