Greetings. I have a DR750s2CH, (had a DR 650 2CH before that), purchased 2 years ago when they first came out. Had my Samsung Note5 set up to connect for WIFI, notifications and provide Hotspot; had no problem seeing network until today. When I downloaded the latest firmware, June 2019 and tried to find the network on my new Note10+, it was there briefly then gone; could not connect. So I returned to my Note5, it also did not show the network on new firmware. However, I opened the Blackvue app' wifi, it linked directly to my wifi connections still not seen, but then it connected automatically to the Note5. (INCORRECTLY CAMERA TELLING ME IT WAS ALREADY LINKED DIECTLY TO WIFI.) But showed me I was still connected to my house WIFI! I added the new Note10+ hotspot with the Note5. I keep it as a backup phone; intuition wins. I logged in with the Note10+ for notifications. Have to drive away from home WIFI to see if it will connect to the Note10+ hotspot. I think clearly it is the new firmware, they added a new shortcut direct to the phone's WIFI network. Performed fine before this change. The only problem with the WIFI which I journeled a claim under warranted but never resolved was the fact on start up finds WIFI hotspots programmed into the cloud's 3 options, then drive away home WIFI, links to phone hotspot in van, but coming back home intermitantly (80%) camera fails to search and relink to same home WIFI in the evening but early 5 am 6 hours later it then connects itself! For years now..van is 5 feet from WIFI booster, no excuse but maybe solar flares?!
