There’s nothing more frustrating than having your desk or bed be just outside the range of your Wi-Fi network. If you face this dilemma, try a cookie sheet. It can extend your Wi-Fi reach by redirecting the radio waves beamed out by your router.
How to do it:
The cookie sheet works just like a satellite TV dish. Place it right behind your Wi-Fi router. It focuses the router’s energy in one direction rather than a full circle.
We downloaded an app that displays Wi-Fi signal strength in dBm and stood in one spot about 10 feet away from our router. A cookie sheet was placed behind our Wi-Fi router while we remained stationary. We started off with a signal strength of -52 dBm and saw the graph climb to -45 dBm when we set the cookie sheet behind the router. We took the cookie sheet away and it dropped down to -55 dBm. When we repositioned the sheet behind the router, it shot up to -42 dBm, then dropped to a mere -50 dBm when we removed it one last time. Success!
