I am regularly confronted with electronic devices and systems failing. The wifi goes off occasionally in my house. It is occasionally so slow in public as to be useless. The router goes down and the Internet connection sometimes comes to a complete standstill. The smartphone is known to slow down, occasionally stop and worst of all the programs can freeze or shut me out for want of the password. The TV connection to the wifi seems to be whimsical.
So how do you fix these problems?
In the days of mechanical devices I had a whole repertoire of fixes that usually worked. They ranged from taking the device apart to using graphite or oil on moving parts. Mechanical and electrical mechanisms were generally easy for me. And other people, which is why there were repair shops on nearly every retail street.
Now in the electronic era, the steps to fixing a problem are very different. The skill is not commercially widespread enough to have repair shops in abundance.
My sequence of restoration usually starts with depriving the device of all power. Unplug it or remove the battery and reboot. Then repeat the loading or opening process. Move on to plugging and unplugging. From there the process gets even more obscure.
In many instances the easiest thing to do is find a teenager to help or call a help line associated with the product.
Quite a difference between our previous mechanical-electrical world and the electronic one today.
