Welcome to LQ!

However, we need a lot more specific information from you. What make/model of laptop are you using?

What linux distribution do you have installed (linux distributions are collections of programs all running on top of the linux kernel, some examples are Ubuntu, Debian, Mint, Fedora, CentOS and each one has versions like Ubuntu 11.4, Debian 6.0 Squeeze, etc.)?

How are you trying to connect? Wirelessly to a local wireless router? To a 3G/4G network? To wired network?

as pljvaldez asked before - what type of connection are you trying to connect to ? Is it wired or wireless ? Which release are you using? Ubuntu 11.04? If you are unable to connect to wireless, first try connecting to a wired network and see if ubuntu wants to install some updates.

The more important question is this: wired or wireless networking?

If wireless, the most likely issue is something to do with the driver for the wireless chipset.

Try connecting to your router with an ethernet cable and booting the computer, then test the connection.

Open a terminal and run the command lspci, then post the output here; that will provide information about your networking hardware.

Again, what model of HP laptop? What version of Ubuntu?

What is the output of lspci at the command line (place in <code> brackets in your response)?

EDIT: Oops, forgot to submit this and someone beat me to it...

Sorry for the late response from yesterdays post had an emergency to take care of. Any who I have an HP laptop pavilion AMD running on Ubuntu 10.10 Maverick Meerkat. I have charter communications cable that has a desktop on the direct ethernet cable and the laptop is wireless. I was using the laptop pulling off my wireless network with no problem then one day I turned my laptop on and it couldn't connect to the internet. No server to be found. I haven't done anything differently than before. I hope this info helps. Remember Im a computer dummy!

Can you post the output of lspci so we know what networking hardware you have?

It sounds like it was working fine on Ubuntu until one day it didn't. Who originally set up the laptop on the wireless connection? What make/model# is your wireless router?

May it be that there is a physical switch to turn of the wireless on that laptop. Since we can't see the wireless device i the output of lspci I would assume that it is switched off.

Try sudo lshw and enter your user password. You're specifically looking for something networking related, my guess would be a broadcom chipset. But if some sort of wireless card doesn't show up, it would seem you have some sort of hardware issue. Maybe the wireless card was disabled in the BIOS or something..?
