Hello,
So, I got some time this week and was able to fully debug the issue: Here is what came out of this:
Wi-Fi 2,4 Ghz on and Bluetooth Headset (Marshall Major II) OR Speaker (JBL Pulse 3) connected.
The internet drops after few minutes of streaming. (around 30 minutes) Yesterday after the (nice) update, it was less than 30 minutes.
I have heard that there might be audio stuttering, but this is not the case. This makes the whole projector unusable. The only solution is to turn off and, on the Wi-Fi, back again. Watching a 1h45 minutes movie, I must reset my Wi-Fi at least three times which is crazy annoying.
I have tested everything mentioned here in this forum and other out in the internet:
I changed the channel. I switched to a faster DNS. I set a static IP address (You will not believe how many suggestions are out there). Unfortunately, I am unable to get a 5 Ghz router but all my other devices do not have any issues.
I am able to stream hours of Movies and TV Shows to other devices while having my Bluetooth devices connected to without ANY ISSUE. Not even audio stuttering.
Obviously, even in LAN the device becomes unreachable. For example, Plex app allows you to have an endpoint so that you can check networking logging “remotely”. However, the devices become unreachable when the issue mentioned above happens.
The temporary solution is to use speakers or headphones with cable, but since I discovered that besides the high pitch noise that the charger make when the projector is fully charged, I hear also the high pitch noise in the headphones/speakers.
To me it looks clearly, it’s a hardware issue and nothing more. Projector for Wi-Fi and Charger for the high pitch noise (even through headphones).
Looking forward your reply,
Salim
