For some Quad Cortex users, you will encounter an issue with the WiFi not working. While your first thought might be yoy have a defective unit, the issue might be more simple than you think.
The Quad Cortex only operates on the 2.4GHz band of WiFi. This band offers slower speeds than 5GHz WiFi, but is more reliable and can penetrate obstacles better.
Chances are your WiFi isn’t setup to work with the 2.4GHz band and you could be transmitting on 5 instead.
You can experience this problem if you’re connecting to a personal hotspot on your phone. Many smartphones use 5GHz by default and if you do not enable compatibility mode, it won’t transmit on 2.4GHz.
If you’re not using a hotspot, then it’s possible your router/modem is setup to support multiple bands and is hopping between bands. This was the case for my Google Nest router and wireless points, my QC wasn’t working with my WiFi properly due to the lack of 2.4GHz configuration.
Still, despite the fixes, you will find that the WiFi on the Quad Cortex is still a weak point. I am not sure if it is the casing, weak antenna inside of the device or software related, but even with full reception at 2.4GHz, it can still be quite slow.
Hopefully, these issues are resolved with the Quad Cortex desktop editor and we can update it and interact with the cloud through it.
