Hi, after extensive tests, I noticed the following issues with WiFi and Bluetooth:
- when a 5 ghz wifi is present, I can see TWO identical SSID, one with WPA (real) and one with WEP (non-existant).
Every now and then I loose connectivity, and can resume it only after switching phone to plane mode, and remove it immediately, in some cases also need a reboot. When trying to connect, it remains stuck in various stages: obtaining IP from DHCP, connected but without Internet, or connected but passing no traffic.
- Bluetooth itself seems to be crashed when issue with wifi occurs: it can't connect properly to my car speaker, even after turning them off and on again. Again, only a plane mode switch or reboot resolves the issue.
Another thing I noticed with wifi is that the control panel tends to maintain the previous list of network found, and it takes several seconds to regenerate the correct list of present wifi.
In my opinion, you should review and debug drivers for wifi and bluetooth, and tests them extensively.
