Devices Not Connecting To 2.4ghz
I had an issue where my interent went down for several hours due to my ISP. After resetting the modem and rebooting the router, the following devices will not connect to my 2.4Ghz radio:
Nest Thermostat (Main Level)
Nest Thermostat (Second Level)
ADT Security System
Chamberlain Garage Door
These devices connected without any issues prior to my interent being down for several hours. What's odd, is the Nest Thermostat's show they are connected however, the Nest iOS App shows them offline. All devices have assigned IP addresses. I've rebooted the router a few times and STILL cannot get the devices to connect to the 2.4Ghz radio.
I do have othe devices that are able to connect / are connected to the 2.4GHz radio.
I'm baffled. Thanks for the troubleshooting help.
After hours of troubleshooting and about a half dozen factory resets, I was able to resolve my issue.
Does anyone remembers the google program 'Namebench' from several years back? Well, it turns out that I was still using my DNS / Alternate DNS server addresses from almost five years ago. Everything worked great and I had not issues on the XR500 until my ISP went down for maintenance / upgrade early Thursday morning. After the maintenance / upgrade was complete, I had to call my ISP in order to get online as they needed to do some things on their end.

I noticed after doing factory resets, all devices on my home network seemed to work flawlessly. After loading a recently saved CONFIG file, I once again had issues with the same devices (connected to home network / unable to communicate with server). Another factory reset, and this time I set up my home network from scratch, using the almost five year old DNS / Alternate DNS server numbers. The issues persisted. A performed a few more factory resets, trying differnet configurations, and I was still having issues. On a whim, I decided to "Get Automatically from ISP" the "Domain Main Server Address". Guess what........I"m BACK IN BUSINESS! :smileyvery-happy:
I, like most others, am still have random disconnects (usually Nest Cam during the late night hours) that are very brief (just a few seconds). I've noticed no random disconnects of any LAN connceted devices, including both the Xbox One X and Xbox One S which are both set to 'Instant On'.
Ultimately my problem was a result of 5 year old 'Domain Main Server Addresses" I was using from the Namebench program. I'm now using / trying some recommended DNS Server Addresses and they seem to be working great! Thanks to all that helped me with troubleshooting this problem.
I hope that anyone having issues like mine might be able to use this information as a reference.

I need to clarify something (unable to edit original post).
Two of the devices are actually connected via LAN : Chamberlain Garage Door / ADT Home Security System. The Nest Thermostats are the two devices that show they are connected (when checking Nest Thermostat) however, the Nest iOS app shows them offline.
**UPDATE**
When I check 'DEVICE MANAGER', it shows the Nest Thermostats connected to the 2.4GHz radio however, the Nest iOS app shows them offline.
I'm beyond baffled as to why the four devices I'm having trouble with worked just fine yesterday. It seems no matter what I do (unplug devices / delete devices / removed reserved IP addresses / ect), they will not connect.
- For the WiFi is smart connect disabled and are they connected directly to the 2.4GHz band? Untick disable IGMP Proxying in WAN Setup also.
I have Beamforming enabled and MIMO disabled. Using Smart Connect. Manual Channels 11 and 48 and Auto 20/40Mhz. I believe enabling 40Mhz only worked as well, however after downgrading FW back to initial on my XR450 the other night, I haven't seen as many disconnects wthe the NEST controllers. I was seeing a few random disconnects with the most recent version of FW.
- Okay I would try turning off the XR500. Reboot the modem and wait 1-2 minutes for it to fully boot up. Then turn on the XR500 and wait for it to fully boot up. Disable Smart Connect then connect to 2.4GHz and see if it resolves the issue.

Disable Smart Connect then connect to 2.4GHz and see if it resolves the issue.I've done that a few times already. But, I will try it again and disable Smart Connect. The Nest Thermostats show they are connected to my WiFi when checking the settings / techincal info on the thermostat, and show up as connected on XR500 when checking the Device Manager. The other two devices are connected via LAN to a switch. They wil show up as connected on the XR500 when checking the Device Manager. It's just the iOS apps that are showing OFFLINE / NOT CONNECTED / SYSTEM IS OFFLINE.
BTW, I have devices that are currently connected to the 2.4GHz radio w/o any issues. I also have devices connected via LAN to the same switch and no issues with those connected devices. It just seems to be four devices with issues (Nest Thermostats / ADT Home Security System / Chamberlain Garage Door - MY Q).
Bizarre for sure!
Thank for the continued help.
Well at least he got internet back. ISP messed up on there provisioning of his modem. :smileymad:
Has the other effected devices been powered OFF for a full 1 minuted then back on?

Yes. I even had them powered off for 1+ hours.
Let us know if a factory reset helps. Try a different router as well.
So hows that custome DNS? :smileyvery-happy:

I recommend giving 1.1.1.1 and 9.9.9.9 a try for DNS. I've been using them since I first hear about them earlier this year. Been having good services thru them.
Keep in mind that some DNS do changes over the years so keep and eye on things and if you notice internet issues, sites not loading right or no getting internet resources, go back and set auto detect on the router and let it get DNS from the ISP first to check for resolution. Then go find other custom DNS.
Enjoy. :smileywink:
