Lenovo ideal pad 1i keeps disconnecting from the internet!!!

Y’all please help…

I have an ideal pad 1i laptop on windows 11 and ive had it for about a year now. The default browser is Microsoft edge. In the beginning i never had problems with the wifi disconnecting or with it running slow until about january ish. Now I cannot play games or do any school work without it disconnecting from the wifi every few minutes and is very slow. Ive tried reconnecting and resetting but nothing worked. It is constantly disconnecting while im reading articles for school and while im doing assignments and quizzes and playing and game. It’s hard to do any school work while it keeps disconnecting. It always says that my schools websites or canvas’s server “cant find an ip address” or “your disconnected” I cant do anything on this laptop i peace!! It gives me problems with the internet as soon as i turn it on!! Do i send it to get fixed or purchase a new laptop that I cannot afford!!! I also do not know much about hardware stuff with laptops.
