Laptop Wireless Internet
 

Hi,

Just got a new laptop and removed windows and added Ubuntu and cant seem to get the wirless Internet card to work.

How can I go able resolving this? do I need to get Linux drives or firmware?

Thanks Justin

What make and model computer? What type of wireless chip?

Hi Frankbell,

It's a Compaq Presario CQ62.

The Wirless Chip is PCI Express Fast Ethernet controller.

you should find out chipset with command lspci and than try to install driver

Help
 

anybody else have any ideas about how i can go about setting up my wireless?

Thanks

That would be your wired chipset, not wireless.

How do I go about finding my wireless info for my laptop?
What commands do I run?

Thanks

Justin

The lspci command should show it.

lspci
 

This is what the lspci gives me...

That AR9285 chipset is supported by the ath9k driver, it should work out of the box with any kernel newer than 2.6.29. I'd expect any Ubuntu release since 9.10 to support it without a problem.

Run "lsmod|grep ath9k", if nothing shows up, "modprobe ath9k". If ath9k is listed in lsmod, but you still have problems, run "dmesg|grep ath9k" and look for errors.
(All without quotes, of course)

Try this link. Which version of Ubuntu are you using At the minute?

Below are the inks to install the wireless drivers for your card in lucid lynx or Mveric
Lucid
Maverick

http://wireless.kernel.org/en/users/Drivers/ath9k

Look at the output of the console command lsmod and see if the ath9k module is being loaded. You can also look at the output of the dmesg command and see if the wireless adapter is being recognised.
dmesg | grep ath9k

this is what i get running those 2 commnads...

I dont know how to interpret it.

Justin

It looks like everything is just fine, is the network manager not showing the device or is it just not connecting?

i dont see the device listed in the network manager?
