But if you have an older router, those updates ensure your router's software is running at its best and most efficient. Yes, we know-running firmware updates is annoying and time consuming. (It's also probably the first thing your Internet provider will ask you to do when you call to complain, so head them off at the pass.) And if you buy an outlet timer, you don't even have to worry about it: Set the timer to reset your router once a day at an off-peak time. It sounds simple enough, but a majority of tech support problems can be cleared up by simply resetting or rebooting your router or modem on a regular basis. You should also avoid placing your router near metal objects, which can absorb signal strength. If you want an easier fix, most routers have an automatic option to find the best channel for your location.

Using online tools- Acrylic Wi-Fi for Windows and AirGrab Wi-Fi Radar for Mac, for example-can help you find the right wireless channel with the least amount of interference.

To reduce interference, place your router away from household appliances and set it to a different wireless channel and frequency. Microwaves, cordless telephones, flourescent lights, and even other routers in your neighbor’s home or apartment may interfere with your Wi-Fi signal.
