Why does my internet randomly slow down? - 1

I have a portable Wi-Fi modem which plugs into the computer via a usb charger that randonmly slows down for no reason. It only has four gigs so i don't download anything or watch any videos all i use it for are facebook, skype, minecraft and instagram any idea why it does this?

Because you have wireless internet service. The signal will NOT be the same everywhere. You could turn around with it and the signal may drop. Interference in many forms can disrupt your signal strength. Why people spend that kind of money for some capped internet service and a poor quality signal is beyond me.

Dear please clear your web history, and add a better antivirus in your system…
