If you ever have an internet connection error you might consider using your phone, if you have a mobile internet connection, as a mobile hotspot. That way you can connect your device to the internet through your phone's mobile data connection.
Learn to set it up though before needing it, then you can switch it on quickly when you need to. Be aware that this will use up your mobile data allowance, so use it wisely if your allowance is small like mine (4GB per month). : )
I have set up a routine on my Galaxy S21 that, when I poke an icon, switches on my mobile data and mobile hotspot, then all I have to do is turn on the wi-fi on my desktop PC and connect to my mobile hotspot in the list of available networks. You can also connect through the USB port on your phone without the need for wi-fi (USB tethering).
