I have 8 clusters of ePMP GPS radios. Temps hit -4F yesterday. i've spent the entire day today truble shooting and eventually replacing radios on towers. I can confirm EVERY radio with mac 00056CExxxx is having issues the KEY here is CE in the mac address. unfortunatly I just purchaced another 10 radios and they also have CE in the mac.
We need a fix ASAP. It's not getting warmer untill march.

5 radios upgraded to the early beta let's see what happens tonight. It's very cold
Current Temp 16°F
Feels Like 6°
Light Snow
Tonight Low: 9°F
Hello,
If you are having devices exhibiting problems in cold weather, please use the software from the following URL on these devices:
This will help as we have tried this out on several customers and their devices successfully.
In about a week, we plan on releasing an official load of software, 2.6.1, with this fix included.

LOL. It’s -31c here (-24f) and its been considered ‘‘unseasonably warm’’ for us this time of year. Normally, we’ll hit -43c (-45f) for overnight lows in January.;Our all time record low in town is -53c (-64f). Temps in the 9F to 16F range is literally T-Shirt weather for us. 
So - I’m glad to hear that Cambium has found/solved this issue. It’s obivously a major concern for anyone in our climate. Good work Cambium.

Oh thank God! This really screwed us this weekend and we were at a total loss why this was happening other than it got really cold. Gonna try this out and report back.

We are experiencing the same issue and are in the Chicago area. We have had GPS and non GPS with problems. The MACs start with . 000456C. W spent all day yesterday trying to figure it out and have some very angry customers
We have 70 of these deployed.

Hi WOW-access,
Please install the firmware from the link that Dan Sullivan has provided above. This should resolve the cold issues until we get a beta release out later this week.
Thanks,

The files to upgrade to 2.6.1 Beta in this forum appear to have fixed our issues in cold weather. That was painful. I'm glad this was addressed very quickly but... Ouch.

We got -21 yesterday. I update one ptp at 5:00pm yesterday. The other reboot but not the updated one. So i will update other ptp link as well. For now it's look like a good fix.

I also had multiple management/reboot problems with cold weather and last firmware seems to fix the issues ! Is there an official release date yet ?
Hi. Where can I get this 2.6.1 beta firmware to try? I am subscribed to the Beta forum, buy I see nothing there… Saskatchewan is forecasting -50c to -60c tonight.

So am I correct to assume that APPX is for GPS Sync radios and SMPX is for non-GPS Sync radios ?
After upgrading SM's Tools> Software Uprade says: "Software Version Not applicable" instead of 2.6.1 or whatever I would expect it to say. Assuming this is normal since it says this on every single radio I upgraded to 2.6.1

We must be about this update, it's not all radio that are compatible, that why Cambium didn't let everyone download the firmware.
"Cambium didn't let everyone download the firmware. "
Yeah they did, it was a Cambium person that posted that link in this thread and said to use it on any radios that appeared to be having cold weather problems.
