Weird, it’s like the right time to shift subsidies away from oil and coal and towards renewal and nuclear was 30 years ago, not 4 years from now.

Will they be raising their rates in India? Because that’s where Spotify thinks I live now.
- Comment on Have you encountered this? 1 week ago:
It’s getting to be less common. A lot of newer/trendier places are giving their wait-staff tablets (which are also handling ordering, seating status, etc), or at least portable payment terminals.
Some of the big established chains have kiosks at the table where you can order apps/drinks directly, pay, play games.
I’ve also been to several places that’ll put a QR code on the receipt for payment. They may also have their menu online that you can get from a QR on the table. As an added bonus that usually means their online menu is actually kept up to date.

- Comment on Wi-Fi 8 won't be faster, but will be better - more details emerge just hours after Wi-Fi 7 protocols are officially ratified 1 week ago:
Yeah, I know.
Add to that “secret” repeaters. Take for example the Amazon Echo Chime. Combination Smart doorbell speaker/802.11n repeater (2.4GHz only).
You connect to that, good luck.
Oh and people installing repeaters not knowing how they work, putting them someplace with a piss-poor signal and putting their computer next to it, thinking it will be better now that they have “full” signal. Their laptop may have a strong signal to the repeater, but the repeater to the AP is weak, so everything connected to the repeater is weak.

It’s often not a matter of speed but of reliability.
Simple fact is, there are very few occasions where you truly need more than 10Mbps or so, which can handle 1080p, or 25 for 4k.
High speeds are great for the infrequent download, but for most day-to-day internet tasks…it’s largely unnoticed.
The real killer of wifi is latency, jitter, and loss. And these will present themselves as slowdowns when browsing or low-quality video when streaming…but on a sensitive application (gaming, real-time voice/video, many enterprise/corporate VPNs, especially under heavy use). And there’s tons of factors that go into causing these conditions on wireless that are simply not a concern on wired.

Yeah your wifi sucks dude. Or your area.
It’s pretty much impossible to get decent wifi in a dense urban area where there’s competing signal.
The channel has to be clear before any station can talk. So if there’s another ssid or another router on the same channel, you’re waiting for it.
More devices on the wireless (including your neighbors wireless, if you’re on the same channel) means more waiting. More waiting means slower speed.
Add to this that most AX+ gear is defaulting to 80MHz channels and avoid UNII-2 bands (for good reason), bringing us back to 3 usable, non-overlapping channels on 5GHz.
Add to that, that a lot of consumer gear defaults to a static channel. Or says “auto” but really just sticks to one channel. Xfinity routers are notorious for this.
Also, no broadcast/multicasr suppression and enabling legacy rates, also default behavior on a lot of consumer routers and sometimes even unchangeable. Legacy rates (support for circa-2000 802.11b) define the minimum speed that is allowed (usually 1Mbps), and that speed is used for all broadcast and multicast. And these get said by the device and then repeated by the router.
Now we also have smart speakers (like Sonos and Google) that use multicast to make multi-speaker groups. That destroys the wifi. Worse, if your neighbor is playing music and you’re on the same channel. It’ll destroy your wifi.
Printers and their drivers like to spam multicast too. Even if they’re wired, because its still the same network.
Old unused port forwards too. Your router will keep looking on the wire and wireless networks for the destination, using ARPs (which are broadcast traffic). If the IP is offline, it can spam the network looking for it.
If you want good wifi, find a clean channel and thoroughly understand www.wiisfi.com. It is by far the best deep dive on wireless and many of its flaws.
What it doesn’t talk about is shit mesh systems. You want a decent mesh it must be tri-band with a dedicated backhaul. Even that is gonna slow down if you’ve got multiple hops between device and gateway. Much better to wire in all the endpoints.
But if you’ve got a clear channel and good, well-configured hardware, and good placement…you can get good speeds on wireless.
But you really should still use a wire (or something like MoCA or Powerline if that’s not an option) for anything more than light browsing and streaming services (not realtime!). Wireless is prone to latency and jitter and some applications (voice/video, work VPNs, gaming) are far more sensitive to that than others.
