Our WIFI Booster
Ever since we setup a wifi router in the living room, the two rooms at the long corner of the house have been sufferring from not-so-good wifi signal. From our reading (yes, wo do read!) both rooms were having RSSI signal value of below -70 dbm which is considered really poor.
So, finally today, after looking at an antenna booster template, we tried this out ourselves! Armed with two pieces of hard folder cards, a sharp scissor, some glue and the always-trusted Diamond aluminum foil — we made our own WIFI booster.
Step 1: Cut the folder cards to follow the antenna templates.

Cut the card according to the template.
Step 2: Grab the aluminum foil from the kitchen

Use aluminum foil as the reflector of the antenna
Step 3: The backplates should be fully covered with aluminum foil

The backplate covered with foil. Since you have two antennas, make a pair!
Step 4: Attached the other portion of the antenna as cut from the templates

Looking great, make two of this.
Step 5: Finally, you can then inset the booster into the WIFI antenna.

Both boosters is now attached to the WIFI antennas
You can then twist them around to get the most optimum position.
RESULTS:
Without Antenna Boosters

The first two lines are the signals registred at the back rooms, at -81 and -74 dBm (not good); while the 3rd line is registered at the living room area.
After Antenna Boosters Installed

Signal gains after installation of WIFI Booster
The antennas look really weird and laughable (yes, even Pudding was giving us the-not-so-confident meows while this was being made); but the bottom line is: we get an increase up to 11%. The signal in the living room has also increased from -35dBm to -32 dBm; the best part was we are able to get, at times, above -70dBM in both back room!
Yeahhhhhhhhhhhhhhhhh!!! Cheers sanggalas.
