Quote:wifi card

wlan0 which is your wireless is showing up. Your keyboard and bios and operating system is not blocking wifi.

You threw me off with wireless card. Which I guess it is not (inxi would have shown it if it was a card)

so now.

Code:
sudo lsusb -v

with the wireless adapter hooked up and a fresh boot. Also a


Code:
sudo dmesg | less


you're running the dmesg command and then giving the output to the less command. (thats what the "|" does) the less command receives that output and allows you to browse through it with the arrow keys.

So far I see nothing blocking your wifi connection at all.

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


Re: wifi problem... - millerose23 - 12-15-2014

no matters for now what device i have plugged in...couse if i disable my phone..nothing change... sudo dmesg | grep firmware this command give empty output... really tnx again for your answer and sorry for my sad english!!

Re: wifi problem... - rokytnji - 12-15-2014

Empty message on dmesg grep firmware means no firware requested or missing. If something would have been spit out. Then firmware missing would have shown. No message. No missing firmware.

That post was dated in April and is relevant since Linux Lite is based on Ubuntu 14.04

Truthfully. I have not used ndis-gtk in ages.

Here is the download link for your Windows wireless drivers to use in ndiswrapper or ndis-gtk.

Here is what kernel.org has to say.

With that amount of info I could get that working on my box here in Texas. But because I am so far away.
I cannot seem to help you much further on this issue.
Maybe some other member can assist in this. Sorry Man. I tried.  :-[
