Tips For Fine Tuning Your Wi-Fi Coverage

  • Old devices have legacy radio technology. While Wi-Fi has great backwards compatibility, you really need to upgrade wifi router. Legacy device hold back the performance of the entire network. If you have less than 802.11n (Wi-Fi 4) and/or your device only supports 2.4 GHz your options are slim. We suggest considering upgrading to a newer model that supports 802.11ac (Wi-Fi 5) or the latest technology 802.11ax (Wi-Fi 6).
  • Try first limiting 5 GHz channels using 36 through 48 and 149 to 161 if possible on your Wi-Fi router.
  • Walls and large furniture are examples of things that limit Wi-Fi coverage usable range. 5 GHz also doesn’t cover as wide of a distance, but 2.4 GHz is rarely worth
  • As RF signal conditions worsen, the maximum throughput on user device operating at distances with low speeds will negatively affect all users
  • Radio frequency channels used by Wi-Fi are shared with everyone. If certain channels are in your proximity you need to find new ones. Non-Wi-Fi devices may also use these channels and testing will not report those, but this is rare at 5 GHz. Try multiple channels to test performance.
