We need reliable, real-world ~20mbit/s for our warehouse scanners, not 382722 theoretical Gbit/s 5cm from the access point. And roaming that works instead of stupid clients clinging to somewhere or being thrown into a reconnect loop when the AP tries to get them to roam. I know this is theoretically possible today. But in the real world, I have inherited the setup, so AP locations are fixed for now, clients are some random old handhold motorola android devices and interference is high.

In comparison, DECT has been flawless in the same space. Set and forget, just works. I always wondered if we could have a kind of DECT proxy on the LAN, and have the ERP application talk to that proxy using DECT... I mean, it's a few EANs and stuff, DECT could handle this easily.

I was recently made aware of WiFi HaLow. Official standard, ranges into the hundreds of meters. Speed suffers at long ranges of course, but still respectable (50-100kbs).

Difficult within the EU due to ISM limits.

Maybe ok for your garden camera where the authorities just don't care. But no go for any industrial usage.

euduhdhbene 30 minutes ago | parent | next [-]

We have devices sending telemetry and occasional OTA updates without urgency (if it takes a few hours to get it over it’s not a problem).

If you need consistent MB range traffic for cameras I wouldn’t advise it but for low (5kbs) traffic it can be attractive. A few thousand bits can encode quite a bit of information. Don’t be fooled by the “kbs”.

Usually this rules are for experts who have to implement the limits. They should not be exposed to end-users.

Dead outside the US unfortunately, worse range than regular wifi due to being strangled by lower channel width and ridicolously low power limits. The two bulky HaLowLink routers are the only off the shelf thing with support for it, it's nonexistent as a wifi standard.

I was so excited when I discovered it a few months back after struggling for years to set up reliable wifi for outdoor robotics, only to realize we can't have nice things. The struggle continues.

I've had similar issues with clients (Blink camera sync modules) connecting to far-away APs instead of the much closer router. I could not force them to connect directly to the router no matter what.

Turns out the 2.4 GHz radio of my router had died (Fritzbox 7590, apparently a common issue), thus forcing 2.4 GHz-only clients to use those other APs.

spockz 3 hours ago | parent | next [-]

In ubiquity gear you can “lock” devices to a specific endpoint. I suspect ultimately you would prefer to have failover available but at least for troubleshooting you can see how it connects to that specific AP. Similarly you could see the amount of clients connected to an AP on every frequency and WiFi version.

Thanks - I’ll try this. I have a problem where my kindle only downloads books in one room (but I can make purchases in any), and I’m pretty sure that it’s connecting to a different AP and doing something stupid in the process

We have about 20 client devices, I would very much prefer to throw a bunch of APs into the warehouse and it just works - DECT can do it, so wifi should, too. I'd settle for 10mbit/s!

> or being thrown into a reconnect loop when the AP tries to get them to roam

The AP does not have visibility into what the client actually sees, and no, a coordinator that has knowledge what the APs see isn't that much better.

Imagine a situation with two APs and a client being in the middle of the two in a RF-impeded situation (i.e. your typical office building). AP1 may "hear" the client better (i.e. it gets a higher RSSI and SNR), but the client may reject it in favor of AP2 because the client sees a better signal coming from AP2 due to reflections, a powerful RF signal from a floor above interfering with the channel of AP1 or God knows what else.

RF is a weird world.

avhception 2 hours ago | parent | next [-]

I'm no RF expert, and we're not a big company. I wear many hats, from DBA to local WiFi expert. And while there are certainly limits to what can be achieved without dedicated experts, I want to stress how DECT in the very same scenario just delivers unwavering reliable operation without me ever giving a hoot about RF interference or 802.11k or r or any other implementation detail.

fragmede 3 hours ago | parent | prev [-]

How much money do you have? Nokia's Centralized RAN basically solves for cellphones by not choosing between AP1 and AP2. The device yells out a packet, both radios hear it, and the signals are combined in baseband processing. Wifi 8 doesn't quite do this, maybe 9's gonna have it. Or the patents run out and the telecom networks cooperate and everything gets a cell modem.

I recently upgraded from a WiFi 5 router to a WiFi 7 one, and my bandwidth increase was a grand 0% (that's ok though I was actually just sick of my old router's shitty UI!)

There is about 10m and a brick wall between my AP and my desk so yeah, a fancy new MCS that can theoretically deliver 25Gbps was just never gonna be useful to me.

Also I've worked on (other non-WiFi) 802.11 products where our competitive edge was all about interference motivation. Our competitors at trade shows would see the demos and say "that's fake, you guys are cheating". So I have the feeling that in general there might be alpha in more resilient wireless links.

fmajid 2 hours ago | parent | next [-]

For a while I had wireless mesh networking in my new house, until I finally got around to pulling fiber to get a proper 10Gbps backbone. Upgrading from my UniFi WiFi6E AP to a WiFi 7 doubled my effective throughput as measured by SpeedTest. This in a 1930s house with solid brick construction.

How often do you see your router's UI to justify any change?

jofzar 3 hours ago | parent | next [-]

I had a TP-Link deco, which while great as mesh, you couldn't limit the speed of certain devices. Which was again fine, except when the PlayStation 5 in a room could literally saturate the whole 250mbs bandwidth of my internet and when it would do an update would make our whole houses internet unusable.

It's seriously impressive how it wasnt possible to set per device speed limits or even QoS which has been a thing since like 2007

It's the first because we finally caught up on speed. We have it better than I imagined possible.

Last year, I saw 1600 Mbit/s from the Internet at a normie's place with an ISP-provided router. Still have a cat 6 cable around the living room but haven't used it in the last 2 years. Not exactly wifi but I routinely get 600-800 Mbit on 5g networks in crowded areas.

It's 2026 and I'm running more cat-6 in my home to all my static devices. My theory is using wires lowers wireless contention, leaving more WiFi for the mobile devices.

I put in 2 CAT6 wires to every room in the house (4 in my office, 4 in garage), with one big PoE switch in the garage.

Everything with an Ethernet port is wired, wifi is for phones and tablets only (a few UniFi WiFi 6 APS).

Works great!

Internet has never dropped for me while working, family loves the always working NAS streaming via wired Apple TV.

I wired up my office, and thr speed test after was slower than on wifi. haven't had a chance to debug it yet, but it's something to consider.

ButlerianJihad an hour ago | parent | prev [-]

A few years ago, for some reason my ISP began to screw up my WiFi. Tech support could not help; I had at least two devices showing the same symptoms; at one point I even shut down my home connection out of frustration. I could only think of two possibilities: that there had been some kind of security event that tripped their security AI and was blocking my WiFi (and inexplicably leaving all Ethernet connections unhindered.) Second possibility: they were deliberately (but deniably) messing with my WiFi access at home so that I would use more mobile data. In fact a salesman told me that would be a logical move. Except it was affecting my Chromebook too.

So my only choice was to purchase a third-party router/WiFi. I did not want to make the network more complex, but if my ISP router couldn't provide WiFi, it would need to happen.

So now I have a working WiFi 7 router, and my ISP's device is permanently in Bridge Mode. I went to the hardware store and purchased a bunch of little cable staples, and I nailed up an Ethernet cable from the router to the bedroom. There are 3 desk positions in here that can be reached by Ethernet cable.

Unfortunately, if I am out on the balcony, I normally need to use WiFi, because I can't fully shut the door when a cable is snaking out of it. Also, I picked up a little USB-C-Ethernet dongle for my phone, if worse comes to worst. The bandwidth is great; besides, my downstream is only 100Mbps, so who needs overpowered LAN bandwidth?

ksec 3 hours ago | parent | prev | next [-]

In typical WiFi fashion, for all the WIFi 8 features to working perfectly and debugged we have to wait for WiFi 9 [1]. This was true with WiFi 5, WiFi 6 and WiFI 7.

Unfortunately IMO WiFi router brand selection is getting increasingly small. I have no issue or problem with using UniFI myself. But it is not something I could recommend to family and friends as they don't know how to set it up. Eero is not available to much of the world outside US. I just wish Apple revive its AirPort Express business.

Oh no. I haven't even upgraded to WiFi 7 yet!

BlackRabbit1 5 hours ago | parent | next [-]

You are not missing too much.

One of the core features (MLO) is currently mostly scam. APs/Clients negotiate the protocol (and it shows up in the status) but doesn't it to either increase robustness or bandwidth (by combining/switching between two frequency bands).

Also the driver quality is a huge mess.

(We tested it using the latest generation Cisco Enterprise gear but also with Prosumer stuff like Ubiquiti or TP-Link)

But honestly: we need WiFi-8. It finally brings infrastructure-controlled roaming which is super important for any VoIP service.

greenavocado 4 hours ago | parent | next [-]

> infrastructure-controlled roaming

802.11 r/k/v exists

BlackRabbit1 3 hours ago | parent | next [-]

That's not controlled, seamless hand-over as we know it from GSM/3G/LTE/5G for 30 years now.

We basically miss all data (received stations/signal levels from both sides, Bit Rate errors, etc.) for making roaming decisions and then to softly connect them to an AP you want them to be on.

Enterprise WiFi is currently mostly "This is a list of APs you maybe can connect to.. have fun.. if you can connect we pre-seeded the AP with some crypto data, so it doesn't take ages to negotiate. Here's your (more or less friendly) disassoc. Fuck off bye."

It does somehow work for stationary setups - but as soon as you have mobile traffic (like walking around or machines moving) with multiple APs the quality hits the shitter brutally.

Currently this gap is being filled by industrial 5G with dedicated frequencies. It's crazy expensive.

avhception 4 hours ago | parent | prev [-]

On paper, yes. In the real world, that random Android client is clinging to an AP that can barely hear it while a better one would be available.

It sounds like you're talking about throughput aggregation, which indeed no device currently supports.

Aren't devices with Intel Wi-Fi 7 BE200/BE202 are supporting that?

As well as latest Samsung phones?

BlackRabbit1 2 hours ago | parent [-]

AFAIR: the BE200/B202 only have one radio. So no parallel streams on two frequencies.

But they are the best cards around if you want to play with Wifi-7 on Linux. But always go for the latest wireless-next kernel + firmware blobs. Also they are not compatible with AMD mainboards (go for Qualcomm then).

The upgrade to 6E was a big jump in my network (Wifi7 Unifi Wall AP). On the same spot, the M3 MacBook (6E) has basically zero lag over VNC, while the M1 MacBook (6) has a noticeable lag. It’s a bit mind blowing how big the difference is.

InvaderFizz 4 hours ago | parent [-]

That is likely because of AWDL and your WiFi card doing channel hopping to listen between packets.

Set your channels to 6/149/37 and the lag will probably vanish. Exactly because of this, I only run those channels, even across multiple APs.

In Europe, you may need to use 44 instead of 149.

There is currently no good way to keep AWDL off other than a script that just turns it off every 200ms, because of course Apple. Also, not always an option with work issued Macs.

silisili 3 hours ago | parent | prev | next [-]

Not missing much. I feel like it's in many ways misguided. 6ghz ftw because 5ghz penetrates too much and causes noisy neighbor problems. Well, from my experience, 6ghz doesn't penetrate at -all-. So unless you live in a barndo or studio apartment, it's mostly an exercise in frustration.

My family doesn't know that the WiFi AP is not the DECT base. They understand when I tell them, but that's gone after a week. They use the words WiFi (or, as we say in Germany, WLAN) and "Internet" almost interchangeably. At work, too. "Internet kaputt" can mean anything from "my device is broken" to "our ERP app is not doing the right thing / responding too slow".

That is true everywhere. I think operating systems could do a better job at informing about the health of the internet connection in words the user understands. What seems to be the current bottleneck:

swiftcoder 5 hours ago | parent | prev | next [-]

Makes sense. Last router upgrade I reached the point where my wifi speeds (at least near the router) were indistinguishable from plugging into gigabit ethernet - that's fast enough for any home task, and the same speed as my fibre uplink. I can't see chasing speed further, outside of very specialised setups.

riobard 4 hours ago | parent | next [-]

When talking about network bandwidth, it is custom to measure in bit-per-second therefore the "bps" notation. If you convert to bytes, it is highly recommended to use "b/s" notation instead, i.e 150MB/s, to avoid confusion.

tveyben 4 hours ago | parent | prev | next [-]

But IIRC the de facto unit for network transmission speeds are bits - not bytes - pr second, and when it’s more the rule than the exception than people write ‘B’ in stead of ‘b’ then the confusion gets even higher..

No. Just no. That speed is only possible when standing at a Nevada test range, in late spring, on a ladder, holding the router above your head, with a black cat sitting on your left shoulder. Any minor change from those parameters and your speeds will be 30% the theoretical maximum ... maybe 50% if you can only find a grey cat.

LogTrim 5 hours ago | parent | prev [-]

The peak-speed arms race stopped being interesting to me a while ago. I don't need 20+ Gbit/s theoretical Wi-Fi. I need the connection to stay boring when I'm at the edge of coverage or the neighbours are hammering the same spectrum.

The 95th-percentile latency and packet-loss targets here seem much more meaningful than another 2x headline speed increase.

My only scepticism is how much of this survives real consumer hardware. Wi-Fi 6 had things like OFDMA that sounded great on paper, but support/implementation was pretty uneven.

itopaloglu83 4 hours ago | parent | next [-]

My neighbor thinks that they can increase their 100Mbps ISP speed by having 5 or 6 access points at 2.4GHz in their 1400sq ft (~140m2) apartment.

There’s so much interference that the package dropout rate is around 40% at 2.4GHz usually.

spockz 3 hours ago | parent | next [-]

Having a AP in every room can be as significant boost if the walls impede the signal a lot. In fact we have one wall which is especially bad. Stand in front of it or next to it and reception from the front of the house is decent. Take one step back behind the wall and signal drops to less than 10%.

So having the 5-6 AP is not the problem, then shouting at max power is the problem. Especially “gaming” routers tend to do this.

Gigachad 4 hours ago | parent | prev [-]

2.4ghz is pretty bad but the 5 and 6ghz bands don’t really travel far. I’m in a dense area and 5ghz works great while 6 has basically no detectable traffic.

Agree completely. Higher speeds are a bit pointless for most users. Unless you have an extremely fast NAS, where you need to copy (not stream) data over Wi-Fi, you're unlikely to be anywhere near the current limits.

I'm using 802.11ac and see no need for higher speeds.

Higher speeds automatically means less latency and that does matter, especially if you are into stuff like games where every millisecond matters.
