Hello, ultraviolet:

It would be helpful if you give us some information by posting the output of the following command (entered in a terminal session):
Code: [Select]
sudo lshw -C network

driver=rtl819xE
That's not a standard kernel module .. have you manually installed a third party driver ? .. can you remember where you got it, and can you provide a link ?

Can you unplug the USB wireless adapter .. then open as terminal and run:
Code: [Select]
sudo lspci -vnn | grep -i net
and
Code: [Select]
rfkill list
and
Code: [Select]
iwconfig
and
Code: [Select]
sudo iwlist scanning
and
Code: [Select]
uname -a
copy the output as you go into a text file .. then plug your USB wireless back in and post what you copied to the text file back here.

Hi, ultraviolet!


BTW, when pasting your copied output (which will be rather long) please embed the text you paste (the blue stuff) in so-called "spoiler" tags that look like this

Code: [Select]
[spoiler]pasted text goes here[/spoiler]
The powers that be here at the forum refer to the result as a "spoiler" and it saves space when pasting longer outputs (as you will see).

Thanks,
-- Slim

Hmm .. that looks like it's working too me  :-\

What makes you think it's not working ?

If you click the network manager icon by the clock, is your network listed ?

Is your network called "BTHub5-PJPQ"

What is the output from:
Code: [Select]
lsmod
and
Code: [Select]
modinfo rtl819xE

Does the internal wireless start working if yu run:
Code: [Select]
sudo modprobe -r rtl819xE
then
Code: [Select]
sudo modprobe rtl8192se
?

nothing came up in the terminal for me to paste here. although those commands have disconnected the inbuilt wifi. so in the bottom right of my screen i'm unable to select a wifi network; i just get the broken cable icon

OK, rebooting will get you back to where you are now.

Can you run:
Code: [Select]
cp -v /var/log/dmesg ~/Desktop/dmesg.txt
You'll then find a file called "dmesg.txt" on your desktop.

Can you host that file online somewhere, and post a link to it ..so I can take a look at its contents.

OK, I'm getting confused here by all the different drivers .

Can you boot the PC without the USB wireless adapter (don't just unplug it I need you to BOOT the PC *without* it plugged in), and copy the output from these commands to a text file so you can post them here later.

Code: [Select]
lsmod
and
Code: [Select]
lshw -C network
and
Code: [Select]
iwconfig
and
Code: [Select]
ifconfig
and
Code: [Select]
sudo iwlist scanning

Now plug in your USB adapter and post the output you copied earlier back here.
