my wifi is not working properly

hi guys,

I'm using zorin os 8 educational x32 (new to linux)
1. how do you find out easy about the versions of any programs installed in your system? (e.g.-ubuntu version)
2. my wifi is not at full speed, there are any settings to boost it up?
3. I'm having this wifi led-button blinking always, is that ok? if not, how do I stop it?
searched multiple forums to find solutions but none worked and now I'm a little bit confused

Thanks a lot... cheers!

Hi,

firstly look at the update guide and update your system fully using a "Network Cable" and then you will see if there are any improvements to the system:

RESTART AFTER UPDATING!.

To find details of your Ubuntu version: System Settings > System > Details

For installed software:

Regards Wolfman

Please also post the results of the following terminal commands:

lspci -nn | grep 0280
lsusb
sudo lshw -c network
sudo rfkill list all
iwconfig

Thanks for your quick reply, guys. I'll be reinstalling it once again through network cable to see what's happening and I'll let you know. Then I'll be posting everything here. With Zorin OS 8 Core installed do I have to load ALL sofwares that came with Zorin Educational by myself, isn't it? I as understood, there are 90% of them included... One other thing I have to mention here, I BLOODY LOVE ZORIN OS 8! When I'm getting it right I'll be good to go;) Windows sucks and is already past-tense for me. Reading through Internet, I couldn't believe it myself how Microsoft is'handle' things on the market. Anyhow, I'll not get into it here. Thanks again and talk to you later...

Here are the results and hope you'll find the issue. Thanks...

Please also provide the results of

Code:

iwconfig
lsmod

I want to see if your signal strength and quality are ok.
Do you also get any disconnections...? In any case we could try to see if disabling the nBand helps things.
In terminal give:

Code:

sudo gedit /etc/modprobe.d/iwl3945.conf

In the document that will open, add the line:

Code:

options iwl3945 11n_disable=1

Save, exit, reboot and see if that helped.

I have also seen this thread that the poster says that he got it working pretty well using ndiswrapper (windows wireless drivers).
