Update on my issues.
Still having intermittent connection issues on two cams here. Sometimes they load quickly, as they did before the latest firmware release. Sometimes they take 30-60 seconds to load. Sometimes they hang on “getting video data 3/3” and never connect. Sometimes one works and the other doesn’t. Sometimes it is vice versa.
I did hear back from Wyze on the support ticket I submitted. They had me run RouteThisHelps on the two cameras and came back with my router isn’t an 802.11ac router and I have ~40% packet loss, and the cameras need 802.11ac to run consistently. Well according to my tests, I have 0 packet loss, and the cameras ran consistently on that router before the latest firmware. Replied to their message and they replied that they wanted me to run RouteThisHelps on my router. Did that, and am waiting for a response from them now.
Admittedly my router is an older model, but it is an N router and ran these cameras perfectly before the firmware update. I am not averse to getting a new router, if I actually need it, but I don’t believe that I do. There is nothing in their FAQs saying that these cameras need anything other than a 2.4 GHz network, using WPA or WPA2. No mention of these needing an 802.11ac router to function reliably.
As it stands, these cameras are useless to me if they are not reliable when I am away from my home network. Of course I am past my return window with Amazon, as I have had them running perfectly for 2 months or so until the latest firmware update.
