I found something very interesting that might shed light on WiFi woes. So many posts on wifi dropping.
After several sessions of flawless and strong wifi connections (dongle and built in), i finally hit a snag! Finally, just to sympathize with many of you.
Simple, it was my first night out with battery power for the AVX mount, connected via dongle. Fully charged, no slewing at all. All my previous sessions were on AC power to AVX. Well, tonight AVX was powered by Celestron power cell pro (the bigger one). Wifi or more specifically - CPWI kept erroring out - saying mount has stopped responding. Laptop showed wifi connected, but CPWI had lost connection, and it was not possible to get it back without restarting.
I tried about 5 times, failed each time. CPWI lost connection in a few mins. Laptop showed connection.
So having proven battery power was some connected (pun intended) to the connection drop, I brought in an AC connection and boom! No connection drop for 2 hours! I was struggling to stay connected for 5 mins on battery.
So not sure what this is - but hoping people can pool their experience to help pinpoint. Somehow on battery power, the connection is not holding over wifi -- I am not sure if its actually wifi dropping (because laptop still showed connection to Celestron) or the information being transmitted over wifi is getting stopped some how (I suspect the latter).
This means, on battery power I should use USB to controller and use wifi when i have AC power.
