The pandemic COVID-19 outbreak forced companies to continue with work-from-home policy to maintain social distancing and for business continuity. More and more of us are working from home these days, and that means your home’s WiFi networks are more important than ever.
Anyone with a fixed-line connection will know that their WiFi drops whenever the power goes out. It is annoying if you are in an important meeting/webinar through Zoom, WebEx, or MS-Team, and there is an interruption due to power cuts.
