my wireless networks dont appear

Can you give some details about the adapter and things like the releaseof ubuntu....basic stuff.

your question is so basic that it is unanswerable.

1. What is the make and model of your PC

2. How are you intending to connect to the internet: USB Modem, Wireless with USB dongle, Wireless with inbuilt card, LAN cable etc.

3. Do you dual boot, if so what is other OS and does wireless work there?

4. Which version of Ubuntu are you using.

5. Can you connect to the internet using a LAN cable? If yes it will make things easier.

 As you have mentioned wireless can you open a terminal (CTRL+ALT+T) and enter the following commands

sudo iwlist scan

Do you see any networks listed, and if so does this include yours?

Hi,

Please first connect your wired network adapter 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:

If you are using the Gnome interface, open the Terminal console via "Applications->Accessories->Terminal"

If you are using the Unity interface, the easiest way to open the Terminal is to use the 'search' function on the dash. Or you can click on the 'More Apps' button, click on the 'See more results' by the installed section, and find it in that list of applications. A third way, available after you click on the 'More Apps' button, is to go to the search bar, and see that the far right end of it says 'All Applications'. You then click on that, and you'll see the full list. Then you can go to Accessories > Terminal after that.

The methods in Unity are:
Press Control-ALT-T key combination.
Dash > Search for Terminal
Dash > More Apps > 'See More Results' > Terminal
Dash > More Apps > Accessories > Terminal

Step 2: Please copy-paste the following command from https://help.ubuntu.com/community/WirelessTroubleshootingProcedure 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 lsmod. 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!

Step 3: 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 4: Please also specify the exact model and make of your PC (if known) on this thread

Step 5: Please also clarify if you installed Ubuntu to the harddisk and are running from a harddisk install OR if you are only testing Ubuntu in a LiveCD session.

Regards,

Mark
