Why is my WiFi so slow? "Steer" clear of the 2.4 GHz band, part 2

Which frequency band are you using, the 2.4 GHz band or the 5 GHz band?
The FCC allows WiFi to operate in two different frequency bands: the 2.4 and 5 GHz. All too often, the culprit of slow WiFi is use of the 2.4 GHz band, which offers slower data rates and is often oversaturated with WiFi and non-WiFi devices, like microwave or baby monitors. OK, how do you know if any clients are using the 2.4 GHz band? Luckily, with a MetaGeek Plus subscription and compatible wireless adapter, inSSIDer can show you this.
Step 1: Get a WiFi adapter
Grab a compatible WiFi adapter from the list above. We recommend the Edimax EW-7833UAC because it’s small and powerful.
Step 2: Fire it up
Plus the adapter into your computer and open inSSIDer.
Step 3: Find your network
Find your your wireless network’s name, or SSID, and dive into the Network Details by clicking the binoculars icon.
Step 4: Find your radio
Keep an eye on the clients column and see how many clients are on each radio on your network. Find your 2.4 GHz radio (hint: it will be on channel 1-13) and click the binoculars icon again.
Step 5: Find the problem device
If the problematic device is listed under your 2.4 GHz radio, try turning the WiFi on that device off and on again to ensure it’s choosing the optimal band.
If turning the WiFi off and on again doesn’t help, try moving the client device and router closer to each other
Step 6: Configure your router
If your device is still stuck to the 2.4 GHz band, see if you can login to your router configuration utility and disable the 2.4 GHz radio entirely, forcing all traffic to the 5 GHz band. Not recommended if you have really old devices like a Nintendo Wii or 1st generation ChromeCast! Not all routers will let you do this. If yours doesn’t, go to Step 7.
Apple routers allow the 2.4 GHz radio to be turned off via AirPort Utility
Step 7: Name your bands
From your router configuration utility, give each band its own SSID name in order to segment clients and to ensure they don’t steer down to the 2.4 GHz band. For example, name your 2.4 GHz network "MyWiFi" and name your 5 GHz network "MyWiFi5G".
Step 8: Move device to 5 GHz
Associate your problematic device to the 5 GHz network. Now it won’t connect to the 2.4 GHz network!
