WiFi speeds are usually OK, but the apartments density is so high here (and new `xfinitywifi` APs are often popping up on my channel), that I'm almost ready to move back to cabled for most purposes.
It's 2.6mm diameter, and I had success running it between baseboards and carpet.
My apartment has a nice patch panel though so I don't have to actually run cables everywhere.
It's still amazing to me, though, that so much new gear is still 2.4GHz only. I bought a brand-new, top-of-the-line air filter earlier this year, and even at close to $500, 2.4GHz is the only option.
With an air filter, do you ever want to control it? Naively I'd think that you'd want to leave it on unless you're going to be gone for a week or more. And even in that case it's probably easier to flip the switch.
Would it tell you when it needs a filter change? Would that actually work better than a calendar?
Ethernet is usually <1ms.... powerline adapter i use is about 2ms.... wifi to the same router, is 40ms. 2ms is much more manageable for me than 40ms
My WFH setup is on wifi and I've never had any throughput/latency/reliability issues that made me want to run a cable.
Of course at this point we're close to Wi-Fi 6E hardware and I probably wouldn't have done all of this at this point.
