 matthewcroughan | This spams over and over back and forth on a friends machine | 22:19:40 |
| matthewcroughan | bpi-r4 | 22:19:41 |
| matthewcroughan | I can replicate it on mine too, I don't use 2.4 very often | 22:19:50 |
| matthewcroughan | doesn't happen on 5g | 22:19:55 |
| matthewcroughan | just using your hostapd | 22:20:04 |
 K900 | It's probably doing DFS | 22:20:07 |
| K900 | Or whatever the 20/40 thing is | 22:20:13 |
| matthewcroughan | It spams every second tohugh | 22:20:26 |
| matthewcroughan | * It spams every second though | 22:20:29 |
| matthewcroughan | on the client | 22:20:30 |
| matthewcroughan | so the dmesg is just scrolling this endlessly | 22:20:37 |
| K900 | You can force it to 20 mHz channel width | 22:20:53 |
| K900 | It's not like 40 on 2.4G gets you much | 22:21:01 |
| matthewcroughan | how do you force that | 22:21:55 |
| K900 | Just set the channel width in the config to 20 | 22:22:04 |
| matthewcroughan | I'm not setting it atm though, how is it set? | 22:22:21 |
| matthewcroughan | wl24g = {
band = "2g";
channel = 0;
inherit countryCode;
wifi4 = {
enable = true;
capabilities = [
"LDPC"
"HT40+"
"GF"
"SHORT-GI-20"
"SHORT-GI-40"
"TX-STBC"
"RX-STBC1"
"MAX-AMSDU-7935"
];
};
| 22:22:23 |
| matthewcroughan | is it that wifi4 cap? | 22:22:28 |
| matthewcroughan | HT40+? | 22:22:31 |
| matthewcroughan | wifi5/6/7 have operatingChannelWidth in the nixos module option | 22:23:16 |
| K900 | Yes | 22:23:28 |
| K900 | Well | 22:23:30 |
| K900 | You can remove HT40+ and it should fall back to 20mhz | 22:23:40 |
| K900 | But I think there's an explicit setting somewhere too | 22:23:47 |
 emily | no DFS on 2.4 GHz here | 23:04:23 |
| emily | (2400 - 2483 @ 40), (N/A, 20), (N/A)
fwiw
| 23:04:31 |
| K900 | It's not literally DFS | 23:07:08 |
| K900 | There's a weird dance you have to do on 2.4Ghz to not overlap with other APs much | 23:07:26 |
| emily | ah, makes sense. | 23:11:52 |

 Ando “Thor” Nando | Question re the friendlyelec nanopc-t6 which has an RK3588 cpu. We had a nixos configuration that worked fine with 24.11 but upgrading directly to 25.05 with no other changes broke our build. First with BTRFS kernel module the compilation failed. Having disabled that the sd card generated by nixos-generators doesn’t seem to actually boot at all. Has anyone else seen this issue? | 04:55:55 |
