Can't connect to wireless on HP Pavilion Entertainment PC laptop


I just installed Ubuntu on my laptop. I have a HP Pavillion dv6700 notebook. Had a problem with windows and wouldn't boot. Now with ubuntu I'm unable to connect to wireless. Connects with cable just fine. When I go into the network settings I don't get an option for wifi at all. I have tried installing Wifi Radar application and can't get that to work either. I keep reading posts about checking the driver but can't find the information.

Any suggestions how I can get my wireless working?

It's probably a driver issue.

You could look in the Ubuntu control center and see if there's an item for "Additional Hardware" (There used to be, I know). Clicking that might identify the issue. Be sure to do it with the wired connection enabled in case you need to download something.

There are diagnostics you can use to identify the wireless chipset. This post, though it's primarily about Broadcom, lists them.

Once you identify the chipset, you post it back to this thread and someone will be able to help you.

If it's Broadcom, the rest of the post will also help you.

If you need to know what wireless card you have you can run this command like I did to find out what card you do have:

[redhatcat@ ~]$ lspci | grep -i network
07:00.0 Network controller: Atheros Communications Inc. AR9485 Wireless Network Adapter (rev 01)
[redhatcat@ ~]$

I followed the steps in the link to identify if the chipset is broadcom but couldn't identify. I didn't see any lines that had the chipset. I see a lot of NVIDIA but nothing for the network or wireless.

I also tried the command lspci | grep -i network but nothing showed up with that command.

Any other thoughts?

Thanks for the help.

this information mite be helpful in diagnosing:
echo uname: && uname -a -m -p && echo lspci: && lspci && echo lsusb: && lsusb && echo lsmod: && lsmod && echo ifconfig: && ifconfig && echo ifconfig -a: && ifconfig -a && echo iwconfig: && iwconfig && echo resolv.conf: && cat /etc/resolv.conf && echo route: && route -n
how old is your laptop; according to this page only certain models of that laptop had wifi:

silly question: are you sure your laptop has wifi ?; the result of your lspci seems to suggest it doesnt.

The tool you need to run is called 'Additional Drivers' you can click on the unity dash (Top icon on the unity launcher the one with the Ubuntu logo) then a search field opens up type there Additional drivers and when the icon shows up just click on it. (The incon kind of looks like a video card) Run it and it should notify you about available software for your computer.

When running this application make sure you are connected to the internet hard wired.

Good luck to you and Let us know how it works for you.
