It is newer IKEA device firmware updates that are known to cause issues so just do not update firmware on your IKEA devices unless you are already having major problems with them, (you really should not try to fix what is not broken, at least not when it comes to IKEA devices Zigbee firmware as IKEA’s newer firmware is known to have problems), but that is enough discussion about that in this thread, (please start a new thread if you want to discuss that more).
As for this Zigbee Coordinator adapter (which is what this thread is only about), as long as you follow other best practices then the latest Z-Stack Zigbee Coordinator version from Koenkk’s master branch is generally what is recommend for all CC2652/CC2652P based radio adapters, see → Z-Stack-firmware/coordinator/Z-Stack_3.x.0/bin at master · Koenkk/Z-Stack-firmware · GitHub
Again, first also make sure that you do your best to try to follow follow all other best practice tips as per this guide as it tella how to avoid the root causes for most issues and problems most users have if they do not optimize their Zigbee setup.
