I have noticed that when I turn my raspberry pi off that is running home assistant, my internet goes down. has anyone else had this issue or does anyone know how to fix this?
Can you supply more details about your setup? What kind of equpment and what is connected to what? How it your computer connected to the internet now? Do you have any settings on your router that redirect traffic through the RPI possibly to Adguard for DNS or the like?
Raspberry Pi 4 is connected with ethernet, I do have adguard but it is currently disabled and my internet is still working. I am not too smart when it comes to DNS and networking.
Look in your router settings to see if it specifies an IP address as the DNS server. I bet it does and I bet that IP address is the IP address of your RPI. However, I LOOOOVE adguard and my router points to my RPI IP as the IP for DNS, because - it strips out all the advertisements from all the web sites I visit! However, if I have to power down the RPI, I am always sure to remove the RPI IP address from my router’s DNS server IP settings beforehand - so all the devices on my network do not lose internet access!
Also keep in mind, the DNS settings when you change them on your router, the changes are not seen by all the devices on your network immediately. So even if I remove the rpi IP from my router, when I then power down my RPI some people may complain to me their wqifi is down, and I tell them no it’s not turn your wifi off and back on again or reboot your device (and then they have connectivity again LOL)
My guess is that if you have adguard disabled on the RPI, your router may still be pointing to the RPI for the DNS setting and the adguard on your RPI is just sending those DNS queriues straight out to the internet - unless of course you turn off the RPI!
Adguard also has the ability to act as the DHCP server for a network so your router might not be acting as the DHCP server, but looking to the RPI as the DHCP server. In that case if you want to turn off the RPI and not have everyhone lose their internet access you would also have to turn the DHCP server OFF on the RPI and turn is back on on your router, and then reboot ALL the devices, including the router.
Good luck, I learned networking the hard way - not by training but by banging my head against my home network. Another thing that you will find frustrating with networking is - if you make a change that you think will fix a problem - andit doesn’t seem to fix the problem - to see if it rally fixed the problem you have to just reboot the devices involved - to force them to update the settings to match the change you made to the network - and THEN you will know if your change fixed your problem. Very time consuming.
Google DHCP server to and DNS to see what they mean, and it will start to make more sense.
Did someone set up your RPI on your network for you (sounds like it - ?)?
