12.10, Intel Wireless-N 2230, Not Working

[caeso]

Howdy. I have an HP Envy4 that is running 12.10, with an Intel Centrino Wireless-N 2230 that won't work.

Prior to upgrading it worked (however I had to do a LOT of finagling to get it to), however I did an "apt-get update" and it stopped working, so I decided to upgrade from 12.04 to 12.10 to see if that solved the issue (it has not).

Specs below:

lspci -v

locate 2030-6.ucode

/lib/firmware/iwlwifi-2030-6.ucode

Any help would be appreciated. I know the drivers are supposed to be in-tree, but for some reason it still doesn't work!

HELP! Thanks

Let's see if the firmware file is intact and uncorrupted. Please run and post:

ls -al /lib/firmware/iwlwifi-2030-6.ucode

Thanks.

Interesting. It says that there is "no such file or directory", which i'm assuming means exactly that, however "locate iwlwifi-2030-6.ucode" says it exists in that location. I'm going to redownload it and play it there, see what happens. If you have any other advice on the way i'd appreciate it, and thank you for your help!

I'm going to redownload it and play it there, see what happens.

Meaning what, exactly. I'd think all you need to do is:

sudo apt-get install --reinstall linux-firmware
sudo modprobe -r iwlwifi
sudo modprobe iwlwifi

[caeso]

Woops. I meant redownload the 2030-6.ucode file and "place" it in the firmware folder. Which I did, and now the the wireless works, however it's super slow so I'm thinking I need to disable N. Thanks for your help Chili!

Also, since it works downloading the ucode file, would you recommend following your instructions to reinstall the firmware anyway?

[chili555]

I don't think it's necessary. It's probably only useful for OCD, neat-freak, super sanitary, wake-up-in-the-middle-of-the-night people like ME!

[caeso]

I see, hah. Well thanks. Disabling 11n worked for the speed issue as well. You rock!

Awesome! Please use thread tools at the top to mark Solved.

@caeso: I've been looking for clues on how to disable 11n in my Centrino N-2230 (I have the same unstability problem with mine).
Could you please give me some light on it?

Thank you so much in advance.
