emily | yeah. I just saw that happen with my laptop after fiddling with the channel settings a bit in fact :) | 12:23:02 |
emily | so I guess there is no disadvantage to going as high as you can | 12:23:14 |
emily | well, I guess maybe if you have exactly 40 MHz free and the second 40 MHz is awfully congested but stuff is failing to negotiate for it etc. | 12:23:34 |
adamcstephens | and APs have to support the smaller widths, because not all clients support 40+ | 12:23:53 |
emily | but in this case the spectrum is very clean and I just want to make sure there's a fallback if I'm far away | 12:23:59 |
emily | K900: do you know if there anything I can do to override a specific regdomain rule without just rebuilding the file? it's listed as a maximum of 160 MHz in the 6 GHz range, but I've read the Ofcom publications and done all the searching about the regulations I can etc. etc., and the range specified is already ≥ 320 MHz and I'm pretty sure that there is no specific rule that talks about bandwidth at all, so I'd like to force-enable 320 MHz. | 12:47:00 |
emily | (I guess I should probably send a patch, also?) | 12:47:07 |
emily | in fact the commit that added the seemingly-incorrect information for 6 GHz says "Regulatory update for 6 GHz operation in FI" and cites an EU regulation for the FI update without changing the citations in the GB section at all 😆 | 12:49:47 |
emily | I guess this is motivation to get NixOS on the thing ASAP, because then it would be trivial to patch :) | 12:50:00 |
emily | aha, and https://git.kernel.org/pub/scm/linux/kernel/git/wens/wireless-regdb.git/commit/?id=6c7cbccaee121772a23fa0efdfefcdd8a2369985 fixed a similar issue for other countries. ok, that makes me confident enough to send something | 12:54:44 |
emily | https://lore.kernel.org/linux-wireless/20250529135706.31269-1-linux@emily.moe/T/#u first patch I've ever sent to kernel lists 🎉 | 14:02:11 |
K900 | Hm | 14:03:41 |
K900 | Now I'm wondering what the source is for 160MHz being the limit in Russia | 14:03:49 |
emily | my guess: they set it in WiFi 6E days | 14:06:07 |
magic_rb | I dont eben know where i would look for accurate numbers for the NL. Doesn't help i dont speak dutch | 14:06:12 |
emily | there was no reason to say 320 MHz because it wasn't a thing | 14:06:14 |
emily | going by 6c7cbccaee121772a23fa0efdfefcdd8a2369985 it seems like most countries don't actually specify anything about bandwidth because why would you if you have overall power limits and a restricted range? | 14:06:36 |
emily | idk, maybe it's different in 2.4 GHz because it's so congested | 14:06:45 |
K900 | You know what | 14:06:47 |
K900 | YOU KNOW WHAT | 14:06:49 |
emily | I'm actually unsure why they set an upper limit at all for those cases | 14:07:06 |
emily | it seems like they should support omitting it so that you can continue to use higher bandwidths as they're added to the standards | 14:07:14 |
K900 | Yeah I don't think there's actually a limit | 14:07:34 |
emily | I guess maybe the kernel can't know that it shouldn't go above the upper range, if the total band size is less than the maximum bandwidth, or something like that. | 14:07:52 |
emily | excited to receive your patch in my inbox :p | 14:08:09 |
K900 | Ugh | 14:08:31 |
K900 | Not today | 14:08:34 |
raitobezarius | i was confused at start reading "230 MHz" in the subject until i read the changes | 14:20:57 |
raitobezarius | everyone is having fun with their BPI-R4 fixing all the bugs so i can just have maximal enjoyment when i set up mine | 14:21:25 |
| raul joined the room. | 14:23:58 |
