Yagi Smagi, go for a transmission line or a coplanar. The TL can yield >30dBi gain and the coplanars can do upwards of 20dBi and are easy to make out of quality RG6. Never use foam core, only solid polypropylene or if you have the $$$ teflon. Velocity factor is far better with these types.

Actually the yagi is the easiest to construct like this one here
High Gain Yagi Wi-Fi Antenna
And I only need like 10 db. As it is I need to stick the extender right on my balcony edge which is ugly otherwise it cannot connect inside the house. With the antenna the extender can stay inside.

Can't you get another WiFi adapter that has a detachable antenna?

That Yagi looks like more work to build than a Pringles can antenna, and some other designs which can be found in the classic "Wireless Hacks: 100 Industrial-Strength Tips & Tools", published by O'Reilly. Searching for "Wireless_Hacks_-_100_Industrial-Strength_Tips_Tools_2003.chm" might be fruitful.

That's easier that a coplanar?! How hard is it to cut'n trim coax, solder these links together and be done? Unlike a yagi that must be pointed at the source vs coplanars that are omni and vertically oriented. Need directionality? Add a wire mesh paraboloid reflector that doesn't have to be perfect for greater directionality and or interference rejection. Stick it in a corner out of the way and without getting wierd looks or poked in the eye.
