Most modern routers are what we call ‘Dual Band.’ This means they broadcast both 2.4GHz & 5GHz.
Due to its design Cocoon will only work when connected to your WiFi over a 2.4GHz band.
2.4GHz travels a lot further than 5GHz, it also passes through obstacles (walls Etc.) much easier than a 5GHz band. This means Cocoon is can be placed further away, or even in a different room to your router.
When setting up your Cocoon you should take care to ensure you connect your mobile device to the 2.4GHz band, and set your router to always broadcast 2.4GHz. You can find information on how to set up your router by checking with your internet service provider or the router manufacturer’s website.
