Dips in ET and Stack Temp

Hello everyone,
First of all, I'm not very competent at this type of troubleshooting or even these types of forum discussion. This is all very much over my head, so bear with me as I try to understand these concepts.
I am currently using a Loring s35. We recently purchased a new work laptop for monitoring our roast profiles. I downloaded the latest version of artisan and noticed that I will have these little dips in communication loss in the ET which also affect my ETROR. After a little bit of digging around in the Roast Properties - Data, I noticed that my stack temperature will display as -1 or u.u on the main display. However, sometimes it will display a reading, and when it does, I lose another temperature reading. Typically, this is the ET. Then at some point, usually quickly after, it reverts back to normal. On the previous laptop, we never had an issue like this. I attached a couple images of what I noticed.
Can anyone tell me what they think is going on? Any solutions?
Thank you very much.

It turned out that this is caused by communication errors over a disturbed WiFi connection. In those cases Artisan receives only partial responses and fails to properly assign them to the correct channels. This has been fixed by rejecting incomplete responses and requesting the data again.
