This is on a VIM3 pro running a custom image. We are seeing extremely noisy WiFi signals when the HDMI cable is plugged in.
Note that the following is for a 2.4GHz connection because we are constrained to use this frequency.
For example, HDMI plugged in:
RSSI: -71 dBm SNR: 16 dB noise: -85 dBm
Without HDMI plugged in:
RSSI: -64 dBm SNR: 29 dB noise: -91 dBm
We’ve tried with an headless HDMI dongle and are seeing similar results.
The next step is to try an HDMI cable with better shielding but curious if others are seeing similar issues and if there are firmware or other workarounds for this problem.
Hi @numbqq , I work with @amitu and tested out the image you recommended above. I see a very high noise reading from wlan (and just to clarify the RSSI reading is ok but the noise is causing a lot of interference in some instances). I used the wl tool from Synaptics and that shows the high noise value. For example,
