I don't know if there are many like me, but my Wi-Fi provider is not a very good businessman and I constantly have problems with him because he provides me with bad Internet, but for a lot of money and does not even want to listen to me when I talk about it. Therefore, I plan to use only mobile Internet even at home, but the connection is not very good. Are there any methods that will help improve some signals? For example, portable routers with an antenna?
