If your router is not letting you do the following, you need it very badly despite a good internet connection.  1. Having any lag or delay while streaming HD content, watching your favorite TV shows, multi-user online gaming, and video conferencing.  2. Loss of download speed and performance while connecting multiple devices to the Internet at once.  3. Getting enough robust and consistent signal and coverage to every corner of your house, especially to dead zones. 4. The Internet gets bogged down when the WiFi signals interfere with physical obstacles such as thick timber walls, concrete, and many other types of equipment using the 2.4GHz bands.  Moreover, it often happens with us, and we often accuse our 'Internet Service Provider' because of the slow Internet. That's why buying a long-range router becomes our necessity as it is designed to serve larger spaces and deal with dead zones in your home, without installing any badass WiFi boosting devices such as repeater/extenders and adapters.
