It sounds like you need a new screen, keyboard and printer, and I guess you need to upgrade your wifi too. Or maybeit's a problem with the computer's wifi adapter. But I don't think there's anything wrong with the computer itself.

听起来你需要一个新的屏幕、键盘和打印机，我想你也需要升级你的 wifi。或者可能是电脑的 wifi 适配器有问题。但我不认为电脑本身有什么问题。
