Recently I’ve switched my Internet provider. The new one delivers Internet trough optic fiber to the last mile and the speed should be 100MBit/s. Speed tests over a cable confirm the speed is very close to 100 MBit/s. I however noticed some lags and slowness on my laptop when using WiFi which was not expected. Speedtest.netshowed this:

Remote switches, Internet of Things (IoT) and Smart home in general are quite trendy nowadays. There are plenty of trademarks and devices that allow you to switch lights, heating, garage doors etc via an application on your mobile / web page.
There is one very popular gadget among the Smart housers – the Sonoff. It is actually a trademark that includes various kinds of remote switches. Sonoff devices are getting more and more popular these days because they are small, cheap, cloud ready, easy to use and have built-in AD/DC converter (i.e. no external power supply is needed, just a cable to plug it in the grid). Some sonoffs can be controlled via RF keyfobs.
