This is very useful in places like big city where there are gazillion of devices fighting for airtime. Wifi 7 devices can dynamically switch channel, or even use multiple channels at once which should help a lot in congested environment.
Comment on Wi-Fi 7 quietly took off while everyone was looking at AI

I guess one reason why no one is paying attention to it is because is the Wi-Fi speed usually the limiting factor? In my case I’ve rarely ever maxed out my Wi-Fi 6 speeds. Typically the host or the network that I’m on that is the limiting factor.
Although I’m also in the US so I know where not know for having the fastest internet in the world. Maybe in other areas of the world WiFi 7 might be more useful.

I have one WiFi 6 access point and unless I’m running a benchmark while right next to it, I can’t tell the difference between it and the WiFi 5 access points. I doubt WiFi 7 will make much difference unless you are running 320MHz channels. There’s only enough bandwidth for 3 of them, so good luck getting decent performance unless you live out in the country though.
High speeds are helpful for anyone that has network storage and doesn’t want to plug in an ethernet cable. It doesn’t have anything to do with how fast your internet is.

They’re is so much wrong here I don’t know where to start.

get a better wifi 6ap. You should be getting about 2x the bandwidth. I get about 900mbps on my 5 year old cell phone sitting on the couch.

Wi-Fi 7 smaller width channels to avoid interference. Pretty much everything you’ve said here is backwards/wrong and i encourage you to do some learning on your own.

I’m using a Unifi U6-Lite access point and an Intel AX210 WiFi card on an 80MHz channel. Iperf showed about 600mbps down on WiFi 6 and 550 on WiFi 5 from across the room last time I tested it. There’s no other WiFi networks anywhere near me to interfere with anything.
Smaller channels will avoid interference, but you get less bandwidth on them. The bitrate only increased 20% between WiFi 6 and 7. To get a large speed boost, you need the wider channels that WiFi 7 supports.

The lite, being the cheapest model in that line, unsurprisingly only supports 2x2 mimo. Getting 600mbps from that is actually really good, but given net bandwidth is nearly identical to what is available for wifi5 I’m not surprised you didn’t see much of a difference.
An ap with 4x4 mimo would substantially outpace your wifi 5 router.

On my Archer BE800 and AX201 equipped Thinkpad T14 I’m able to hit just over gigabit on speed tests. Your wifi 6 lite is only 2.4 and 5ghz which is probably why your speeds are so poor, especially if you have other devices on the network.
Unifis wifi 6 offerings were really disappointing. 2.4 5ghz wifi 6 only is just kinda stupid, and I think that’s why it has had such lame reception (no pun intended). Wifi 6 with 6ghz is incredible. Wifi 6 on 5ghz is good. And wifi 6 on 2.4ghz is just kinda awful. It’s not worse than anything previously on 2.4ghz, but it’s just not a step up.

I’m more excited about reducing congestion when more of my neighbors upgrade to 6, so that BSS coloring and other wifi 6/7 features can enable more efficient use of the spectrum. Before wifi 6 most of the upgrades were just increasing data rates, but really lacking in improvements to spectral use efficiency (like the resource unit allocation in OFDMA which splits channels into sub carriers and centrally plans assignment to multiple client devices for simultaneous use which results in much less wasted airtime compared to each device yelling and listening while waiting to see if they can have exclusive access to the whole channel which wastes time) and interference management (like preamble puncturing which allows partial use of a channel when only a portion has interference). In a crowded environment like an apartment building wifi 6 should help a lot in reducing channel utilization.

On a LAN? Pretty easily if you have a gigabit or greater network. Wi-Fi 6 can do close to gigabit but not consistently and needs to be close to an AP, and unlikely a bunch of devices at the same time will be able to do maintain it’s peak.
And WAN speeds of gigabit and greater have become more common, too.

Also the fact that the faster the wifi, the easier it is to block.

These new standards aren’t really targeting residential use so just people shouldn’t care.
Cocodapuf@lemmy.world 5 months ago
Ok, I know why we changed the version naming scheme: a, b, g, n, ac, ax… It was a nightmare, just awful.
But I’ll bet it does still have a IEEE designation, so how does 6 or 7 map to the previous scheme? Also, what’s new, what are the impressive current speeds and features?

WiFi 7 = 802.11be, FYI
jose1324@lemmy.world 5 months ago
5 is AC, 6 is AX

Canada, one of our primary ISPs offers fibre to the home with speeds of 1Gbit and even higher. So many threads on their forums with users confused why they can’t get anywhere close to 1Gbit and it always turns out to be WiFi.
ManosTheHandsOfFate@lemmy.world 5 months ago
I can get very close to 1 Gbit on Ethernet but top out at maybe 400 Mbps on wifi.
AlternateRoute@lemmy.ca 5 months ago
Exactly, wifi 7 will probably get us to or close to practical 1Gbit wireless speed vs theoretical 1Gbit speeds.
stealth_cookies@lemmy.ca 5 months ago
Wifi 6E already does that, I get about 940 Mbps with my phone on my 6GHz network. That is maybe 10 Mbps less than I get wired.

I wonder about ping. Will it ever be on par with Ethernet for online gaming?
