Device falling off 2.4GHz radio since upgrade to 7.20 for NWA130BE.

I noticed that a particular device has been falling off the 2.4GHz since the upgrade from 7.10 to 7.20 for a NWA130BE. I only noticed it because the device is actually rebooting a few times a day since that upgrade.

No other devices are having this problem even if they are much further from the AP. Although I am not certain if it was having signal problems before the upgrade with this AP or an older one, it was not rebooting.

The device in question is a Carrier thermostat: SYSTXCCITC01-A. Details of the devices are under "Downloads for Series A Infinity Touch Controls".

My guess is that the device does not like the weak signal, is dropping a lot from the AP and finally crashing/rebooting.

The unit is an interior wall facing away from the AP and consistently has a signal of -76 or worse. However, my Pixel 7 at the same location can get better than -60 and devices twice as far and through thicker walls have better signal than -70.

I have not changed the transmission power from 30dBm. There are a few other AP in neighboring houses, but less than ten and are weak. I have tried a separated SSID not on the 5 nor 6GHz radios. I have tried different modes (AX, BE, etc.). With and without 802.11 K/V.

Could something have changed that upsets this device? Unfortunately, this devices lacks any useful logs. I am attaching the logs that I could find from the AP with only the lower half of the MAC address changed. It appears that the wireless chip in the device is from Redpine Signals, Inc. which has been defunct since 2020.

    Hi @scf,

    Welcome to Zyxel Community!

    To troubleshoot this and improve stability, please try configuring a separate SSID exclusively for your thermostat on the 2.4GHz band with these settings:

    • Security: WPA2 Personal
    • Band mode: 2.4GHz only
    • Disable: 802.11k/v/r
    • Radio mode: 802.11b/g/n
    • Channel width: 20MHz
    • Transmit Power: Consider adjusting the 2.4GHz radio power. While increasing it might seem helpful for a single AP, careful adjustment is key.

    Let us know if you need Nebula configuring instructions.

    After testing, if the issue still persists, please provide us the diagnostic info file of your NWA110BE so we can investigate further.
