I just got a Slate AX (GL-AXT1800) to replace my old Beryl (GL-MT1300). Everything has been working fine except no matter what I do I can’t connect my Nexxt Smart Wi-Fi LED light bulbs to the router. After resetting the lights they connected perfectly with both the Beryl and an Ubiquity access point within 20 seconds, but time out when connecting to the Slate AX, The Nexxt Home app telling me to troubleshoot the internet connection of the Slate AX which is working fine.
Try turning off your 5Ghz WiFi temporarily while setting up the bulb. Normally your smart device and your setup device (phone), need to be on the 2.4Ghz band and most devices attach to 5Ghz as default.
It still connect to every other access point / router without issues, only with the Slate AX does it not get past “adding device”. The light does stop blinking rapidly indicating something is happening but it gets stuck somewhere in the process.
Current Slate AX settings. None of the steps so far seem to help.
The Smart bulb has 2 methods of connecting, Auto and Manual.
Both worked with the Beryl and access point. Whatever the problem is, it’s specific to the Slate AX
I found the same thing a while back. I have some older devices that wouldn’t connect to my axt1800 but we’re fine with an ar750 and mt1300. This was the only difference I found and luckily it worked. Cheers
