1. Use Speedtest.net when you’re having connectivity problems. Run a speed test to see what your download and upload speeds are. Ideally, they should be at least 50 percent of your Internet service provider’s advertised speeds, with a ping under 100 milliseconds.
2. If the speeds seem solid, make sure that you aren’t inadvertently downloading or uploading anything. Many torrent downloading programs run in the background and minimize into the system tray instead of the task-bar. A good speed test should give you an accurate assessment of your ping, download speed, and upload speed.
3. Check your network hardware. Updates for network cards aren’t all that common, but if your card’s manufacturer offers a newer driver, download it.
4. Resetting your router and modem can help with connection problems too. Most routers and modems have reset buttons, but pulling the power cable for a second or two can do the same thing. Don’t cut the power for much longer, or the hardware may reset itself to factory defaults.
5. Still having problems? Call your Internet Service Provider, which can tell you whether the problem is on your end. As a last-ditch measure, the ISP could reset the master connection to your home.
