In clips viewed nearly 60 million times on social media, people have been encouraging others to place a sheet of tinfoil behind their Wi-Fi router, according to Uswitch.
The theory is that it will redirect scattered Wi-Fi signals back into the router to improve the connection.
That way, the signals don't get lost or dispersed.
It is similar to how a satellite dish functions.

But Richard Dowden, Uswitch's broadband expert, warns that any benefit of the bizarre 'hack' will be small.
'The tinfoil hack could make a tiny difference, as it will cause the Wi-Fi radio waves to be more narrowly focused," he explained.
"However, the downside is that the tinfoil may block the Wi-Fi from going behind it, causing more problems."
It can be easy to give into frustration, and turn to unusual methods of fixing a sluggish Wi-Fi.
But it's best to opt for tried-and-tested speed-boosting tricks, like keeping your router in an elevated space.
Six objects affecting your Wi-Fi
'If you're concerned about Wi-Fi strength, try repositioning your router and running a speed test in different areas of your home to find the optimal spot," added Dowden.
'For the best broadband performance, place your router in a central location, elevated off the ground, and on a flat, open surface.
"Avoid hiding it in enclosed spaces like cupboards or placing it near large obstructions like TVs or bookshelves."
Wi-Fi boosters or extenders are another good option.
These are gadgets that pick up the Wi-Fi signals from your router and spit them out further into the home.
'If your connection is still lagging, consider investing in a Wi-Fi booster or extender - it's a far more reliable solution than tinfoil, which is best left in the kitchen," Dowden continued.
'However, if you're finding your broadband continues to have frequent interruptions, it might be time to consider switching providers to find the one best suited to your needs.'
