Tin Wifi booster.

22C, soft breeze, sun.
Mid-summer’s day: a day of rest and fixing stuff about the house. Take time out with a cup of tea and watch YouTube. Found by chance, a video claiming to cleverly fix Wifi reception problems. image
I certainly do have patchy signal reception in this house. The idea is to partly cut open a drink tin and shape it round the aerial to focus the emitted signal from the router.


I used a Wifi app on my phone to measure the result. The theory sounds likely, but I saw no change in any way.
There was a more measurable result when the phone is put inside the tin. Gain was about 6Db, and turning the tin changed the result too. Perhaps the signal from the router is polarized. The tin is curved in only one direction, it’s not like a satellite dish. This could be useful, if it worked, to get the best out of a mains powered booster, a repeater. That device relies on reception from the router, then re-transmit it at higher power. Trouble is, the connection between the devices does fail sometimes. So, repeater does not offer much reliability.
