How to boost my internet speed?

You could try clearing your browser history, cookies and data caches in your internet browser settings. This might free up some space. Are you referring to a phone's internet or a computer's? If it is a phone and you are using mobile data, one of the reasons your mobile data is slow is that your service provider for your mobile data might be purposely slowing your connection because you are late/haven't paid your bills or they want to cut costs. In this case, you should try to contact your service provider and troubleshoot. Lastly, download safe apps that help boost your internet speed and clear viruses that might cause lag like panda antivirus or hi security app.
