If you're having trouble downloading/installing our games, one thing you might want to try is rebooting your modem/router.
Rebooting (unplugging the power cord, not just turning it off & on) your modem/router for 30 seconds will reset the connection with your ISP. This can fix internet connection problems, improve slow-moving connections and resolve wireless issues, which can even affect your Digital TV service being transmitted over an internet connection. The longer you leave your modem/router continuously running, the more it desynchronizes from your ISP, which can cause packet loss that slows down your connection as bits of data need to continuously be resent. Generally doing this once a month is enough, but depending on the quality of modem/router you have, you might want to do it a couple of times a month.
