Astute Devices can only work on 2.4GHz networks.
Note that if you have a dual 2.4 and 5 G router, switch off the 5G …unplug extenders , then pair devices on the 2.4 Ghz network.
@Silver_212 would I just switch off the 5GHz for the pairing? can I switch it back on after I have successfully paired my device
Many newer routers have dual output frequency 2.4 and 5 Ghz…if you can switch off the 5G transmission, then do so. Otherwise make sure that your mobile device is on the 2.4 Ghz frequency and then pair the Astute device on the same 2.4 Ghz frequency.
