This particular error (DNS PROBE FINISHED NO INTERNET) means that the browser is trying to find the Dynamic Name Servers (DNS) to direct you to the website hat you’re searching and it can’t find one on the network. It could be triggered if you lost the Internet connection, but I also got the error that … Read more
From the series of curious, yet seemingly simple questions, a user recently asked me how to find the running DNS servers on the network and this one is a bit strange because I immediately assumed that the DNS queries were the actual focus. There are some fine methods of doing so, even though the IPv6 … Read more
While the WiFi brings some obvious benefits over the cabled Ethernet connection, we soon realized that the open air is a tricky medium and the WiFi dead spots are a common consequence. The good news is that you can fix them at virtually any budget since it’s there are repeaters, access points and mesh routers … Read more
I have no doubt that while trying to transfer data from your iPhone to a Windows OS PC, you got the following error at least once: Error copying file or folder – A device attached to the system is not functioning. So why does it happen and how can you prevent it from occurring again? … Read more

I have recently tested the Seeed Mini Router to see if the manufacturer has managed to develop a proper Raspberry Pi router and it seems that this small device can also run the Home Assistant software. This way, you can gain the means to rely on an open source, privacy-focused home automation software to handle … Read more
I know that there may be better methods out there but this is the way I increased the size of a Raspberry Pi CM4 module since it would stubbornly prevent me from installing the Home Assistant image on an OpenWRT device.
