That is a realtek chip.

https://wiki.debian.org/rtl819x

Tells you what is going on. Zorin/Ubuntu/Mint are all based on Debian.

Quote:

Non-free firmware is required for all drivers, which can be provided by installing the firmware-realtek package. RTL8192U firmware is currently not packaged (588142).

Pretty much explains it. You probably have the driver but not the firmware installed (maybe, just a guess on my part).

Ask Ubuntu pretty much has Zorin covered for troubleshooting this.

Is that a internal wireless card? If so. You need to turn it off in bios. I had to disable internal wireless card on my Acer Aspire One ZG5 once while troubleshooting it and using a wireless usb pendrive in place of it. Disabling wireless in bios cleared up
that conflict problem for me. This can be verified with a

Code:

lspci -knn

command that will show if that broadcom card is a internal pci card. To avoid confusion in this thread.

Anytime I sub a wireless usb for internal pci wireless card. I turn off the internal wireless card off in bios first.

Edit: @Ztcoracat This might help also (Maybe)

Here is the firmware:

when I open this, I get

rtl8192CU_linux_v2.0.939.20100726.tar.gz

when I right click this file I don't get option to "Open in Terminal"

Am I missing something here? maybe I should extract this file?

sorry to keep asking questions.

Your fine asking questions is how you learn. Your very Welcome-
That file gave me trouble to- It's designed that way.

Now that the driver is ready to be install and your only one click away from installing it(by opening the terminal) let's let that driver sit for a minute and foucus on the firmware.

What rokytnji said makes sense.

Quote:

You probably have the driver but not the firmware installed-

Download the firmware from here-
https://packages.debian.org/squeeze/firmware-realtek

Once your on that page scroll to the bottom of the page on the far left you will see 'Architecture'
and under the word Architecture you'll see 'all' Click on all.
Upon doing so you will be directed to a mirror page. I don't know your location so you will have to decide which http to pick.

If it helps any I am in North America and I generally choose the
http.us.debian.org/debian/ link.

Once you you click on the correct mirror for your area a small window should open and show you the firmware that is 131 kB and read something like this-

Code:

firmware-realtek_0.28+squeeze1_all.deb

Save the file.

I propose that you install the firmware first and restart your computer.
If you still can't get your computer to go online after that; than obviously the driver is not installed.

To install the firmware

-Become root and put in your password.
-Change directory to your Downloads directory $cd Downloads
-At your Downloads # (prompt) run this:

Code:

dpkg --install firmware-realtek (name of your package).deb

Press Enter and dpkg will do it's job to install the firmware.

Restart

Let us know if your online after that.

Hi, thanks again for quick reply.

yes, Broadcom corp BCM4318 802.11g adapter is an internal wireless card.

I had a look at the BIOS and found under "Device Options"
there is an entry called "Embedded WLAN Device Radio" Enabled
is this where I should change to Disable?
do you think is this for the internal wireless card?

I'm waiting for rokytnji to read that output I don't have experience with the lspci -knn command-
I'm Sorry honesty IMO is very important here.

Code:

dpkg: error: requested operation requires superuser privilege.

The dpkg command has to be ran as "root".
Try sudo dpkg --install (name of your pkg).deb

Ztcoracat · 02-13-2014, 07:19 PM

Make sure that the directory that the firmware is sitting in is open and keep it open.
Then open the terminal and run:

Code:

sudo dpkg --install (name of firmware).deb

Hit Enter

Not knowing the root password is a problem yes but this is error is a problem as well.

Code:

dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

I (think) this is a package error that has to be corrected.
I'll have to ask the member that taught me Debian to be sure.
In the meantime I will look up the error and be back to tell you what I have found.

Your Welcome.
I private messaged my friend that taught me Debian to get his take on this dpkg error-
I'll help you tomorrow when you have time.

I found this thread where a man at Ubuntu had the same error as you do.
http://askubuntu.com/questions/79930...al-broken-pipe

You might have to force the overwrite but I do not know with certainty if this is wise for you to do. I will wait for rokytnji and see what he thinks.

Sorry for the delay parker.hugh but I prefer to be safe with your system than sorry. I prefer to learn from one that knows. You agree?

su might not work. Zoring is an Ubuntu derivative, so it might have the root account disabled and use Buntu's retarded system of sudo abuse. If that is the case, you will would need to use sudo for every command requiring root access. But sudo also requires the root password. So if you do not know the root password, then yes, that is a problem. The password can be changed, but I do not remember the exact procedure. It involves interrupting the boot process, changing the password, then booting.

As for the broken pipes; the error message is telling you two versions of the same package cannot be simultaneously installed. Follow the advice in Ztcoracat's link and remove one of the packages.
