[Solved] Wi-Fi Extender

Some time ago I set up the laptop in the study, but wireless reception was intermittent and the signal strength was weak.
At first I looked at software issues - updating drivers helped get a more accurate bar read - but the problem was the signal strength.

Then I looked at technical solutions - new wireless routers, extra antennae, signal boosters.  I also looked at ethernet over powerline solutions.

Finally, after much exploration, I settled on a home-made solution: I cut an empty Pringles can in half and placed this around the router antenna.

Problem solved!
