Step 3: Create a straight line from that mark to the bottom corner & make semicircles on both sides of this line.

Step 4: Now cut along the semicircle you have drawn on both sides to remove the base of the can.

Step 5: Cut along the straight line after that open the can and turn it into a flat sheet.

Step 6: Cover all the sharp edges with electrical tape all along with the can.

FAQs Related To DIY WiFi Antenna Booster

Do DIY Wi-Fi signal boosters really work?

Wireless technology gets more advanced in the last few years. If your router does not support your WiFi connection & most of your devices struggle with the low internet. Then it is high time to upgrade your router & it is worth considering buying a new WiFi signal booster.

Does WiFi boosters increase Internet speed instantly?

Yes, Wi-Fi Boosters can increase the internet connection speed instantly. As your Wifi connection can be slow if there is a lot of distance between the wireless device & router. Signal Booster extends those signals to provide your devices a better internet connection through the router. After that, you will never complain about connection.

Which is the better WiFi repeater or extender?

Yes, there is a lot of difference between both the devices. WiFi extenders are devices that try to extend the range of internet signals to cover a large area of a network which helps every device to get the proper range. On the other side WiFi repeaters are used to broadcast signals again & again where the strength of the signal is weak. Basically, it works on the strength of the signal, not the range.

How far will a WiFi booster reach?

The answer is around 2,500ft. A basic router can only extend its internet range within a limited area of about 150ft (depends on how strong your router is).  But with the extra help of boosters, repeaters & extenders whatever you prefer to say can increase the range up to 2,500ft.

Where do you place a WiFi booster?

Many people ask where should they place their Wifi router to get the maximum range of the internet signal? We suggest placing the signal booster halfway between the WiFi router & a wireless device. As the signal booster should be kept in the range of the Wifi router. If you use a different location every single time then try to keep the booster near the router.
