<Ellied> gaaah this is dumb. My neighbors run the wifi, and they only have 5 GHz up for some reason, and the lovely designers of my HP laptop decided not to include 5 GHz wifi on it
<Ellied> Idk what the hell kind of laptop doesn't have 5 GHz wifi (like, even ones from 10 years ago do, wtaf)
<Ellied> I could just set up wifi-to-bluetooth tethering on my phone, but.... it doesn't have bluetooth either! :V

<UmbralRaptor> Can confirm, have a 10 year old HP(?!) laptop with 5 GHz coverage.
<UmbralRaptor> !wpn Ellied
* Qboid gives Ellied a code-switching feather
<Ellied> Just from what I've used recently: Two generations of Thinkpad, a Toughbook (obvs) and an old Dell. All have 5 GHz.
<Ellied> I think even the PCMCIA card for my ancient Dell has 5 GHz.
<whitequark> UmbralRaptor: ummmmmm no
<whitequark> 802.11a is the same air protocol as 802.11bg, but shifted to 5 GHz
<whitequark> whereas 802.11n on 5GHz uses different modulations on 5 GHz and is much faster
<whitequark> your 10 year old HP laptop has 802.11a, and new laptops have 802.11n, but confusingly will still sometimes refer to the 5 GHz band as "802.11a"
<UmbralRaptor> Apparently the local schools are running 802.11a on their routers, then. o_O
<whitequark> actually, I made a small mistake, 802.11a predates 802.11bg (obviously, as the name implies)
<whitequark> it's just that bg has seen wide *deployment*, and a has barely seen any
<whitequark> it's possible that your school has a.
<UmbralRaptor> Multiple schools in this case.
<whitequark> could be a municipal deployment.
<whitequark> unsurprising that it hasn't been upgraded since forever.
<whitequark> like, 15 years at least.

<FluffyFoxeh> 5GHz wifi has really poor range too
<whitequark> ehhh, and 2.4G spectrum is really crowded

<Iskierka> Is it just me or does it seem like a design flaw to have a reactor that clearly requires gravity for flow on a space station with powered artificial gravity
<egg|work|egg> is there a backup reactor to bootstrap things
<Iskierka> unclear
<Iskierka> there is still power to the reactor's artificial gravity but not to all of the station
<Iskierka> Getting closer it appears to be a tokamak. Not sure if a tokamak core needs gravity for the circulation? But the generation certainly does. But then this also means there's probably a bootstrap somewhere

<bofh> FluffyFoxeh: poor range, but often works better than 2.4GHz in places where the RF spectrum is crowded, for exactly that reason.

<Ellied> whitequark: is a on-air compatible with bg? I know my old laptop has a, and I would be very surprised if RCN (my building's internet service provider) is deploying routers with anything but bg on their 5 GHz bands these days.
<Ellied> wait, I read your responses wrong.
<Ellied> s/bg/n/
<Qboid> Ellied meant to say: whitequark: is a on-air compatible with n? I know my old laptop has a, and I would be very surprised if RCN (my building's internet service provider) is deploying routers with anything but bg on their 5 GHz bands these days.

<Ellied> theeeere we go?
<Ellied> I remember reading that WiFi was 5 GHz before it was 2.4, and assume that my old laptops with 5GHz support are designed for that old protocol, but they also seem perfectly compatible with (if not incredibly fast on) modern 5 GHz networks.

<whitequark> Ellied: there's no bg on 5 GHz
<whitequark> a and b are the same except a is on 5 GHz and b is on 2.4 GHz
<Ellied> gotcha
<whitequark> and g is a slightly extended b
<Ellied> so a is the 'original' 5GHz protocol, and n is the 'new' one?
<whitequark> more or less
<Ellied> and they are on-air compatible?
<whitequark> I imagine if n on 2.4 can coexist with bg, then n on 5 can coexist with a
<whitequark> but I do not know it for sure
<whitequark> there doesn't seem to be any inherent reason that's impossible, I've just never seen an a network in my life
<Ellied> coexist as in "two networks in the same room without interfering" or as in "both kinds of devices can connect to each other on the same network"?
<whitequark> STAs don't talk to each other, they talk to AP
<whitequark> so AP time-multiplexes n slots and a/bg slots
<Ellied> right, I meant an a AP and an n device or vice versa
<whitequark> being unable to frequency-multiplex them, naturally.
