Wi-Fi not connecting on Linux

I’ve never encountered this problem in Windows 10 but I recently installed Ubuntu and this problem have been bugging me ever since. So basically, the Wi-Fi would be connected and occasionally disconnect. The worst part is I can’t do anything that requires Wi-Fi (ex:search the web) even when the Wi-Fi is connected. I’ve tried unplugging and replugging in the Wi-Fi USB adapter, resetting my router, restarting the PC, and resetting the setting to default but nothing works. Someone please offer me some solutions? Thanks 🙏 (PS:I heard it might be something wrong with my driver but I’m just a beginner at Linux and I don’t indents what exactly is a driver.)
