This is a super easy reflector to aim WiFi signals to where you need it. The first one literally too me about a minute to make. I've seen others here but this one is able to stand on it's own and only uses 3 materials
On a side note, Im wishing to save it for a weekly challenge, but whatever ;)
EDIT: About a week later my Wifi In my room crapped out again, I checked my reflectors, both of them had the tape fail.
Fix: I just Hot-glued the skewer back on. If you want to tape, I'd use hocky tape, duct tape, just something better then Scotch tape ;) After I fixed it, Wifi was back in my room
Step 1: Materials
Step 2: Cut the Can
Cut the bottom of the can off
Cut a vertical line in the can
Cut the top as such where most of it is cut but still attached (Picture 2)
Step 3: The Skewer
Open the can and tape the sides to the table, this will make it easier to tape the skewer on
Set the skewer on the can and break to the length you want it (Picture 2 and 3)
Tape the skewer down on the sides and middle (Picture 4)
Step 4: Finishing Up
Also you may want to bend the flap back a little.
Place the can as close to the the router's antenna as possible in the direction you want more signal, I used two. Of course you'll get less signal behind them, but that's an outside wall anyway.
Although simple it works surprisingly well, not as great as most, but seeing the time it takes to make one, work more then well enough for me. They boosted my computer's signal from 3.5-4ish bars to 5 out of 5 bars :)
