Should I install wifi or only Wired LAN for my home

Its a no-brainer. Wifi is a MUST today and tomorrow.

Almost all devices are being wifi enabled rather than being ethernet enabled. Mobile device (Laptop, Smartphones, tablets, gaming consoles, etc) feature only Wifi. Fixed device like smart appliances, TV setop box etc are all wifi enabled even though they may have an additional LAN port. Even PC motherboards are coming with both integrated Wifi and LAN.  The common/ubiquitous network connectivity interface therefore is Wifi.
