Most computer operating software offers a tool to troubleshoot connectivity issues. For Windows, you can find the troubleshooter on the "control panel" under "network and sharing" and "troubleshoot problems."
Once you’ve ruled out a software problem, check all of the cables connecting your router to its power source and your computer.
If the router is properly connected, the next likely culprit would be the router itself. Reboot the router by disconnecting it completely from its power source for a full 10 seconds. No cheating! You really do need to leave it unplugged that long. After 10 seconds, plug it back in and see if your connectivity returns.
If your Wi-Fi signal unexpectedly drops on the reg, check out your splitters. If you have a -7dB splitter to your broadband modem (cable or FIOS) upgrade it to a -3.5dB version to boost the signal. If you have a three-way splitter coming to your router, but only use it for two cables, consider replacing it with a two-way splitter for a better signal.
If your router is shutting itself down intermittently, for no apparent reason, you might have an older router that’s overheating. Check the vents on the router and clear out the dust with compressed air to maximize ventilation and cooling.
If your Wi-Fi is operating but still running slow, consider running an easy test to make sure you’re getting the right amount of bandwidth from your internet service provider (ISP). There are free diagnostic tools you can use to run a speed test on your home internet signal, including Speedtest.net, Speedtest.org and apps like WiFi SweetSpots.
Most internet service providers have diagnostic tools to help you troubleshoot your Wi-Fi problems, including pinging your router remotely to make sure it’s receiving a signal. You might have to wait on hold, but once you get the right person on the phone, they can be very helpful. Also, if you have access to a working internet connection through your cell network provider, consider the live chat options with your ISP customer service, which often have shorter wait times and can be much more effective in solving your problems.
