I am almost completely cured. A strong cough remains... There is no light during the day (they turn it on at evening for several hours and at night when I am already asleep), there is no connection either. I am thinking of finding out from the provider much it will cost to connect via fiber optic and whether it will work for them while there is no light . Because the option with the LTE router now looks not as stable as we wanted. I also continue to look for a power bank suitable for my requirements, but so far without success.

Thanks to the donations that have already come to me, I think I will be able to make myself an Internet that will work even in the absence of light!

You can see how to help me and what I am raising funds for here. -> https://www.furaffinity.net/journal/10399045
