Why is my Wi-Fi slow in certain places?

There could be a few reasons why your Wi-Fi is slow or non-existent in certain areas.

1. The distance between your Wi-Fi router/modem and your device is too far.
2. There could be things blocking or interrupting your Wi-Fi Signal. The more walls the Wi-Fi signal has to travel through, the weaker your signal will become.
3. Numerous Devices: Cell phones, smart TVs, tablets, appliances, baby monitors, wireless security cameras, and wireless speakers all operate on the same frequencies and can lower your Wi-Fi speeds.
