MR18 WiFi stops working when hot


Hi: I've attempted to look up  discussions about this topic. I read them several years ago. My question is: Has this issue been resolved by 'Midas'.   I had heard there was a fix for this a few years back from  a tech at Panergy OEM in NJ. Recently when I spoke with someone there, they didn't say there was a fix and that I would have to give the MR18 to analyse. And, it could be tied up for several months because of 'supply' problems, etc..

Thank you in advance for any help.
