This turned out to be a hardware problem, which became clearer when iw dev command gave different outputs in a matter of seconds, sometimes not showing the wlan0 interface. I had to give it up and use only wired interface for this raspberry.

Have you seen this? https://gist.github.com/telenieko/d17544fc7e4b347beffa87252393384c Haven't tried it yet, was just googling the question because I'm thinking of trying it out and while doing so I stumbled upon your question and the gist I've linked above. Also there's a gentoo forum thread about the topic there: https://forums.gentoo.org/viewtopic-t-...

I'm stealing/promoting @Jaromanda X's answer here, as it's a one-liner and avoids having to use the "GUI" to set the Wi-Fi region/country: sudo raspi-config nonint do_wifi_country XX XX is country code, you can find your country's code here: https://en.wikipedia.org/wiki/ISO_3166-1

Because the information in the question is rather scarce, and "some random video" (as @milliways calls it) of more that 20 minutes doesn't help much, we will resort to basic fault searching. Use https://www.raspberrypi.org/documentation/configuration/wireless/access-point-routed.md as reference material. You state that the network appears on other ...

You need to make a wpa_supplicant.conf file like it is described in this article. https://www.raspberrypi-spy.co.uk/2017/04/manually-setting-up-pi-wifi-using-wpa_supplicant-conf/

If you can do nothing, no keyboard/screen, no ethernet connection, no access to the root partition, then there is of course no possibility to modify and repair the installation. You can only reflash the Raspberry Pi from the image. Or you decide to purchase a piece of hardware to get access to the running RasPi. For this situations the Raspberry Pi has a ...

If you do not have access to any device except the RasPi the only way I see is to use another portable device with a WiFi connection and preferred Linux Operating System, for example a second Raspberry Pi or a Laptop. Then you can walk to the location of a esp8266 and measure the signal strength. You can use the iw, for example: ~$ sudo iw dev wlan0 scan | ...

I fixed my 'no wireless interfaces found' by joining all the groups that the default 'pi' user belonged to. The interfaces message only showed up when I was logged in as 'tech', not when I logged in as 'pi'. Of course, I almost never logged in as 'pi', so it was a happy accident that I discovered this. I added about 10 groups to my 'tech' login, but I couldn'...

User's @user113052 answer worked for me but in my case the answer was incomplete and I can't comment on his post (low rep). File /usr/lib/firmware/brcm/brcmfmac43455-sdio.bin didn't exist on my rpi4b and instead I created this symlink (considering I have rpi4b as there are more files for different raspberryPIs): cd /usr/lib/firmware/brcm/ sudo ln -s ...

I will share more details of what I am trying to achieve. I am going to be working from outside of the country for a few days and I need to have an IP from the country I reside in order for my work computer to work correctly. As 3-party software is disabled and I can't install any tool on my laptop, so my only option to get an IP range from the country where ...

There are several options to achieve what you want. It depends on your use case. If you do not need to access the PC from a device on your local network then you can use NAT (Network Address Translation) which makes routing configuration simple. Here is an example How to make Raspberry Pi 4 as “WIFI” -> “Ethernet” adaptor without add any USB component?. ...

Yes, of course it is possible to configure a Virtual Private Network with OpenVPN using a Raspberry Pi. There is no difference to any other computer. So you will find many examples and setups on the internet, mainly used Installing OpenVPN Access Server on a Linux system. I have setup some VPN with a Raspberry Pi to simplify things for home use. You can find ...
