Introduction: Uni-Directional WIFI Range Extender

The Instructables Book Contest

Easily receive WIFI signals from far away using a standard USB WIFI adaptor and a bit of ingenuity. This Simple idea requires no modifications to a USB WIFI adaptor or your computer. A simple way to increase the signal strength and range of your WIFI. Plus it works with all USB WIFI adaptors

Step 1: Tools and Parts Needed

You need only a few parts for this project and they all are pretty cheap except for the USB WIFI adaptor. ( I got mine on sale for $10, just check the ads)

1 - Metal Strainer/Steamer
1 - USB WIFI Adaptor
1 - USB Extension Cable (I chose a 10ft long)
½” Drill Bit (I like to use stepper bits for metal)
Gorilla Glue (Epoxy works well too)
2 - Zip Ties

Step 2: Drilling the Strainer/Steamer

Remove the Center Post (If your's had one) and drill a 1/2" hole as that is perfect size to fit the usb extention.

Step 3: Glue and Zip-Ties

Insert the Female end of the USB extention (the part that doesnt connect to your computer) into the hole you just drilled.
Then just apply the glue/epoxy and let it sit for 24 hours. This Creates a strong bond between the plastic and metal. I used some tape to help hold the connecter in place while the glue cured. Be sure to apply glue to both sides of the connecter. Once thats dry the next day, zip tie 2 of the metal "ears" so they wont fold in on themselves when you use it.

Step 4: Finish

Just plug the USB WIFI adaptor into the socket on the dish and plug the other end into your computer. Enjoy boosted signal strength and improved distance. Fire up Netstumber or Kismet to really see the gain in power. This works even better than I thought it would. Be sure to leave your comments on how well it worked. Works great for war driving too.

Step 5: Update: Tripod Mount

I decided to make the dish tripod mountable as its really hard to try and hold it to lock in a far away signal. The parts needed are pretty straight-forward.

Tripod
Nut for the bolt on the tripod
9/32" Drill Bit (Stepper bit works really nice for enlarging the hole)

Pick a hole near the edge of the dish and use the drill bit to enlarge it. I chose the one where one of the feet had once been secured. Then just put the bolt from the tripod trough the hole and secure with the nut. Works great.

Can you use this for the phone (like it's plugged in to the laptop but also brings in wifi for the phone?)

Would this help boost the signal to my smart tv?

haave u you check the mineral deposit in an around yr home at all. also u could have rf signals the are interfering with yr wifi. and or some 1 else is hooging yr band with on you. also check 4 competing wifi in an around yr home as well.

Hi, I've got a ? About cell phone service. We live just on the edge of the Verizon tower range would something like this help with cell service? Any suggestions welcomed and thanks!

I bought the adapter and when I connected to the laptop, didn't increased the signal strength. I used to have one wireless icon in the tray of my laptop, now I have #1 and #2 icons, the strength is the same. The connection comes and goes. How this can improve the strength and not show the two icons? Thank you for any help

Good instructable, it's always good to see peoples diy projects, everyone's unique way of looking at a problem, and implementing a solution.


This ones my personal favorite. Picking up signals from hundreds of feet away is cool. Picking up wifi from a couple miles out.

Legendary.

Quick tip on this. The dish strainer is acting as a mirror/focusing the rf single for the usb wifi receiver, however since sits not actually connected to the antenna in the usb adaptor you only get some benefit. Some usb adaptors have an external antenna connector. They are usually RP-SMA, RP for reverse polarity, so the matching connector on the antenna you want to connect it to will need RP-SMA as well, unless you have an antenna wire to connect them with different types of connectors.

this is amazing. but i was just wondering if this would work with a home wireless router setup. also, i want to know if you need to put the satellite with the wireless USB adapter near the window to increase reception.

if your router has a removable antena then yes you can (in theory). if you can find a matching cable for the attachment for your antena, you can use it instead of the usb extender and have the original antena where the usb thing plugged in on the other side of the dish. i might not be making any sense so ill try a makeshift diagram

Quick note here. The longer your antenna wire, the more noise you can introduce into the signal. And its alot easier using moving the router closer to the antenna and using longer ethernet cables then it is to filter out the noise. In addition even the antenna connectors can be noisy. you can get noise resistance or shielded antenna wire but it only does so much.
