 emily | the whole thing where DFS channels take ages to appear is really annoying though, I'll say that. | 12:20:14 |
 adamcstephens | clients can definitely renegotiate a smaller width | 12:22:20 |
| 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 |
