Wifi with new Ubuntu install

Asked by Sanford Schimel on 2010-08-23

I just install Ubuntu on my desktop PC (Intel Pentium 4 chip, 2.8 ghz). I don't have a wifi card installed on the pc but I'm using a Netgear WNA3100 USB adapter. How do I enable the adapter? I tried placing the downloaded firmware into the /lib/firmware folder, but it was already there. Thanks for your help.

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Please copy-paste the following command from this page in browser Firefox into the Linux Terminal.
Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command.
The command STARTS with the word sudo and ENDS with the word dist-upgrade;
So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>,
then enter password when sudo asks for password, then press enter again.

sudo dpkg --configure -a; sudo apt-get -f install; sudo apt-get update; sudo apt-get dist-upgrade;

Then reboot your pc and test if your wireless card is detected, if not continue from the step 3 below

Step 3: Please copy-paste the following command from this page in Firefox into the Linux Terminal.
Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command.
The command STARTS with the word sudo and ENDS with the word restart.
So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>,
then enter password when sudo asks for password, then press enter again.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

sudo apt-get update; sudo apt-get install hwinfo grep; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep 'ound|irmware|eth|ath|wl|ipw|rtl|rt2|b43|witch|ndiswrapper'; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo lsmod; sudo /etc/init.d/networking restart

Step 4: Please post results (copy/paste terminal output) on this thread. The troubleshooters here need to see the full Terminal output from running the above command.

Step 5: Step 4: Please also specify the exact model and make of your PC (if known).

New to Ubuntu: read the Ubuntu Manual, it's very informative: http://ubuntu-manual.org/

Howdy. I'm on a Dell Dimension 2400. No installed wireless network card, only ethernet. Using a Belkin Wireless-N router (model F5D8236-4 v3) and a Netgear Wireless N-300 Adapter model WNA3100

Hello? Anyone?

Wait for the daily coming of Mark Rijckenberg great wireless problem solving here.

@Marco: I don't think I can be of any help in this specific case. The USBID for this specific wireless adapter is 0846:9020

If you do a search on that USB ID on the Internet, you do not find any helpful links.... I do not think that this card is supported yet by Linux.

I recommend selling the wireless card USB and buying one of the following instead:


Sorry that I cannot be of further help....

Can you help with this problem?

Provide an answer of your own, or ask Sanford Schimel for more information if necessary.
