Hello,
If you play a local music without WiFi connection, does it work well?
Works a lot better, no disconnections even after going to idle mode.
There is still a delay in providing audio output, but the delay has
reduced to 1 to 2 seconds, after which I can hear.
If only WiFi connection (without Bluetooth), does connection drop?
No.
Bluetooth operates on 2.4GHz band, so is it possible to connect AP on
5 GHz band?
The 5GHz band SSID does not show up in the available network list until
I am 1 to 2 feet away from AP. This happens regardless of whether
bluetooth is on or off. When connected, I can use that network at normal
speeds even if I am about 3 meters away from AP with a wall in
between. I have a separate SSID setup for both the 2.4 and 5GHz bands. I
did cross check with other devices, and they could connect to the 5GHz
SSID from a 3 meter distance.
Please note that I do not have access to this particular AP anymore than
9 days, so I would not be able to provide information regarding it after
that. The issue with bluetooth and 2.4GHz band is not unique to this AP.
I tried this with my phone hotspot using 5GHz band, but the results are
same for every device - it would connect only within a 1 foot radius.
Besides, bluetooth works fine on 5GHz band, although delay in audio
output by 1 to 2 seconds is present.
Turn off power saveing entirely by
sudo iw wlan0 set power_save off
to see if ease symptom.
No improvements noticed in bluetooth and 5GHz wifi detection.
Additional details I thought would be useful:
I have a wireless usb mouse attached to my laptop,
$ lsusb -d 3938:1031
Bus 003 Device 003: ID 3938:1031 MOSART Semi. 2.4G Wireless Mouse
However, disconnecting the mouse did not make a noticeable difference.
Occasionally, the earphones disconnect when audio profiles are switched,
from A2DP to HSP/HFP and vice versa.
This only occurred with the 2.4GHz band and not the 5GHz band. Software
which records voice does this profile switching.
Thank you for your response and attention to this matter,
Ansh Gupta
