The primary differences between the 2.4 GHz and 5GHz wireless frequencies are range and bandwidth. 5GHz provides faster data rates at a shorter distance. 2.4GHz offers coverage for farther distances, but may perform at slower speeds.
If you live in a condo or an apartment, for example, you probably don’t need 2.4GHz WiFi frequency. I have a lot of IoT at my home and I used to have issues when I used 2.4GHz frequency on those devices.
Typically, WiFi routers come with two frequencies. Make sure that you connect your phones, tablets, and laptops to 5.0Ghz. Here is how I did:
1. Connect to both 2.4Ghz and 5Ghz
2. Set 2.4Ghz to “auto join” off — this way your devices will not auto-join it.
3. Set 5.0Ghz to auto join” ON — this way your devices will always auto join to 5.0Ghz frequency
If you think some devices are far enough to catch 5.0, then set 2.4 for those particular devices to ensure that they are still online.
Ever since I made the changes above, all my Internet of Things devices, phones, tablets, laptops always keep connected.
