On: I amplified my home's Wi-Fi with aluminum foil

Put 'em just behind the antenna like a dish aimed toward where you want to bend the signal to. It's not great, but it's cheap and easy.

Have you tried something similar before? Does it work?

When I had my WiFi router in the basement I placed it in an aluminum oven dish, so that the reflection went towards the ground floor. It was a small but noticeable improvement.

I have, it is hit and miss. But was enough pf a hit to stay in use for over a year back in the 802.11b days. Grounding the reflector should also help iirc.

I am using my neighbors WiFi, which I can only catch in my balcony. He stays above me, but diagonally opposite, so the source is quite away. Any way I can amplify the WiFi strength? So I need the source to be around in order to amplify?

You can put the dish on either end, although if you don't have some sort of external wifi antenna, it'll be trickier
