Ubuntu delayed startup (systemd-networkd-wait-online timeout) #networking #hostapd

https://askubuntu.com/q/1485441/612

I’m going on vacation and I thought that it may be good moment to explore more #Lisp in free time. Because the Net may be poor, expensive or inaccessible and I don’t want to get laptop, I’ve prepared small lab. 😀😉 #RaspberryPi Zero W with #debian and running #hostapd (local access point) will be my Processing Unit. As terminal I will use iPad with ssh client, configured to connect that access point. Additionally I have powerbank 30000 mAh, what gives me the chance to work 24h without plug.

Can your IP camera spy on you? Maybe you should prevent it from doing so. Here's the steps I took to turn a #raspberrypi into a #wifi #hotspot with its own #router that lets a camera talk with the local network but not with the internet.

Driver: Hey, I found a perfect channel for your AP, it's channel 52.

Me: *change the channel on wlan1 to 52*

hostapd: uh, i cannot let you do that because it's marked for radar detection

#linux #hostapd #wifi

For those struggling to setup a #wireless #AP on #Linux using #wpa_supplicant/#NetworkManager, wpa_supplicant 2.10+ apparently has a bug making such networks invisible when configured with #WPA2. #hostapd still works, but so does switching to #WPA3:

i installed #pihole on my #raspberry together with #hostapd to try wifi setups.

After an ultimate fight i upgraded the whole thing from buster to bullseye.

And lost the working setup.

It took me some time to understand that names of interfaces did change, then not mapping anymore the iptable masquerade stance...

I can't use my #laptop onboard #intel #wifi #iwlwifi as an access point using #hostapd for #rdex after all:

```
iw list | grep "Supported interface modes" -A 8
```
does not list "AP" :(

Would have saved me literally hours if this had been the first line of the guides - "first check that it's possible".

The spare USB dongle I have is not supported by Linux, apparently the chipset is supported via #ndiswrapper but I'm not keen, just so much easier to use an old ADSL router to host the wifi...
