There are a few easy ways you can make sure you are getting the most out of your Internet service.

Reset your router every month or so to give the device a break and refresh your Internet connection. If you experience serious speed issues, you might consider resetting your router every day.
Move your modem to a better location. If the WiFi signal from the modem can’t reach you, your Internet connection will suffer. Position your router toward the middle of your house, preferably on whatever floor you spend the most time.
Try an Ethernet cable connection. Everybody uses WiFi these days, and wireless connections are convenient—but they’re not always fast. Cabled connections, like Ethernet, will always be faster and more reliable than wireless ones.
