 K900 | Then it might be time to start looking at the logs on the clients | 13:33:00 |
 crushing-smite | Mind telling me how on windows 😅 | 13:33:20 |
| K900 | It's probably in event viewer somewhere | 13:34:16 |
| K900 | I definitely can't tell you where exactly | 13:34:23 |
| crushing-smite | I don't know what's an event viewer even | 13:34:48 |
| crushing-smite | Well, I'll google around, brb | 13:34:53 |
| K900 | eventvwr.exe | 13:35:56 |
| crushing-smite | K900: there are 3 events for a WLAN connection
- Information - WLAN AutoConfig service started a connection to a wireless network.
- Information - Wireless network association started.
- Error - WLAN AutoConfig service failed to connect to a wireless network. Failure Reason: The specific network is not available.
| 20:16:48 |
| crushing-smite | Nothing else of particular interest | 20:17:02 |
| crushing-smite | That is from Event Viewer -> Microsoft -> Windows -> WLAN-AutoConfig -> Operational | 20:17:36 |
| crushing-smite | I'l try setting AP to WPA2 | 20:24:22 |
| crushing-smite | And it works with windows 11 now with wpa3-sae-transition | 20:31:54 |
| crushing-smite | This fucking sucks, how come this year's laptop and win11 don't support plain wpa3-sae | 20:32:25 |
| crushing-smite | but iOS 18 still does not work... | 20:34:14 |
| crushing-smite | this is very tiresome | 20:34:19 |
| K900 | Have you tried just WPA2? | 20:35:09 |
| crushing-smite | no, it's wpa3-sae-transition | 20:36:01 |
| K900 | Please try just WPA2 | 20:37:35 |
| crushing-smite | Redacted or Malformed Event | 21:55:38 |

 Sean Ross | Hi ElvishJerricco, I just wanted to follow up on this it was a combination of networking.useNetworkd = true; and networking.vswitches.<name>.interfaces.<name> | 17:00:09 |
 ElvishJerricco | Sean Ross: FYI, most matrix clients are really bad at threads. I wouldn't have seen this message if macOS wasn't the only OS with a good notification system :P | 17:02:22 |
| ElvishJerricco | so generally we recommend using replies instead of threads | 17:02:37 |
| Sean Ross | Okay, I'll keep that in mind thankyou. | 17:06:15 |
| crushing-smite | continuing: | 20:44:46 |
| crushing-smite | When I change either operatingChannelWidth from 20or40 to 80 or channel from 36 to 44 (both together, or just one of these), hostapd fails to start with the following log:

| crushing-smite | The br0 interface when hostapd fails to start also loses ability to provide wired internet connection | 20:46:55 |
| crushing-smite | (I've changed everything authentication mode to wpa2-sha256 btw, so clients do work with it now) | 20:47:47 |
| K900 | What does iw phy say for it? | 20:48:49 |
| crushing-smite | Right now, or when it fails? | 20:49:19 |
