Well, that is what is stopping wifi. I see no firmware missing messages. rtl8i92CU is the driver powering you wireless N usb dongle.
I see a mobile phone also. Maybe a conflict between the desktop trying to use the mobile phone wireless and your wireless usb ,
but me being in Texas. I can't tell. It seemed to me that the phone showed its own wireless interface as "usb0" in "ifconfig -a" previous
readout.

Frankly I am stumped a little with the many port usb hub you are using listed as usb 1.1.
So I am wondering if a hardware fault is what is going on here. Like if you have the wireless usb dongle plugged
into the hub and the hub is interfering with the connection.

Just in case wireless firmware is missing

Code:

sudo dmesg | grep firmware
