Indeed, although this type of thing was more common with older wifi generations, so I’m not surprised kids these days wont know.
For example: We cut the top off an old beer can, poked a hole and stuck it onto the antenna to have stable download speeds across a courtyard.
Yeah, one of our problems was rain and thick fog causing massive drops and even disconnects on the connection going out from the router as 2.4Ghz really doesn’t like water. The antenna on our side was fine for sending signals back we just couldn’t get it stable incoming, which is why we did the can trick.
