How can I increase my ESP32 WIFI range?

How to Extend your Range by Extending your Antenna

  1. Step 1) Cut the Antenna PCB with an X-acto Knife.
  2. Step 2) Scrape off the insulation on the Antenna trace.
  3. Step 3) Cut a hookup wire to make our Antenna. This wire should be an odd multiple ( i.e. 3/4, 5/4, 7/4 etc.)
  4. Step 4) Solder a Wire on to the exposed Antenna trace.

Do ESP32 need antenna?

The ESP32-CAM comes with an on-board Wi-Fi antenna, but it also has an IPEX connector if you want to use an external antenna. Using an external antenna can solve problems related with slow video streaming web servers and other connectivity problems.
