Thank you for your comment. The Tech world is similar to the under-developed countries and their shitty infrastructure. I've always been amazed how good the physical infrastructure on the developed world is, but tech doesn't seem to follow through.

Regarding the Macbook, you might have a hardware defect. I changed the Wifi/Bluetooth adapter (Macstore) and it now works flawlessly. It used to drop weirdly on some Wifi networks.
