DIY PS4 Antenna Mod: Boost Your Controller & Wi-Fi Signal for Cheap

00:00:00 - 00:00:23
Nothing’s worse than a laggy wireless controller or weak Wi-Fi despite a good internet connection. Usually, the stock PS4 antenna isn’t cutting it, and you need an external antenna. Here’s how to do it—cheap and easy.

00:00:23 - 00:00:50
My PS4 is hidden in a closet with my home theater setup, but the signal for controllers and Wi-Fi was awful—unusable. Spinning in circles, the works.

00:00:50 - 00:01:16
This mod needs a Torx T8 security bit, Phillips screwdriver, 1/4-inch drill bit, socket, utility knife, and compressed air. The antenna kit costs ~$8–9 on Amazon. Links are in the description.

00:01:16 - 00:01:55
I’m popping off the stickers to access the Torx screws—note that this voids the warranty. My PS4 is an original model, long out of warranty. Remove four Torx screws to pop off the back cover. Super simple.

00:01:55 - 00:02:49
Inside, you’ll see the weak stock antenna cable. Disconnect the power supply with three Torx screws and two Phillips screws. Wiggle the left side and pry gently with a screwdriver to release it. Be careful with the flat cable—don’t disconnect it, just set the power supply aside.

00:02:49 - 00:03:28
Blow out dust with compressed air—mine was filthy, and this was a huge bonus. The antenna connects with a snap ring. Apply pressure to release it, then unwind the cable from its holders.

00:03:28 - 00:04:33
Drill a 1/4-inch hole in the back housing, about four inches up along the top, for the new antenna. Remove the old antenna—it’s useless now. Feed the new antenna through the same pathway as the old one.

00:04:33 - 00:05:33
Snap the new antenna’s connector into place—you’ll hear and feel a solid click. Route it through the cable holders, up the side of the power supply, to the drilled hole about two inches away.

00:05:33 - 00:06:28
Reattach the power supply, ensuring the prongs align with the slots. Push it firmly into place. Reinstall the Torx and Phillips screws as they were. This job took me 20 minutes while filming—faster without a camera.

00:06:28 - 00:07:32
Attach the new antenna to the back housing: washer, antenna, grabber washer, regular washer, nut. Hand-tighten everything—don’t overtighten. Use a socket for a final snug turn. Everything fits flush.

00:07:32 - 00:08:28
Screw on the external antenna, avoiding cross-threading. Snap the back cover on, replace the four Torx screws, and optionally reapply stickers. Time to test it!

00:08:28 - 00:09:37
With the antenna installed, I tested it in the closet with the door closed. It worked perfectly with a fully charged controller—no errors or lag. But at ~40% battery, old controllers struggled again.

00:09:37 - 00:10:45
To fix this, I added an antenna extension cable, running it along my HDMI cord through the wall to behind the TV. This placed the antenna outside the closet, solving all connectivity issues, even with low-battery controllers. Great Wi-Fi for downloads, no lag.

00:10:45 - 00:11:31
For most, the side antenna will work, but my closet setup and old controllers needed the extension. Less than $20 fixed everything, and I can keep my PS4 hidden. Playing Assassin’s Creed Odyssey now—love it!
