Ok, thanks,

I tried with 10 ports powered USB hub with wireless keyboard, it looks better but

I don't know yet, looks like it's not stable..

I tried with ATX power supply, still get the same response, why is that ?

Suggested order of debugging would be:

- look into dmesg and syslog/journalctl for any suspicious messages
popping up when you enable HDMI

- check if order of events has any significance (i.e. HDMI on when
turn wifi on, or wifi on then enable HDMI)

- try a powered USB hub (a passive one may be good enough too)

- try using USB extension cable for the wifi dongle.

The last 2 points are easiest to verify.

Dear Meta-TI Members,

How can I fix the current issue between HDMI port and Wifi on USB dongle ?

Everytime I put HDMI, my USB dongle is down ??

I would start by trying to use a decent power supply.
