Question [Ubuntu 10.04/Ralink RT5390] How to install?


Hello

Someone I know removed Windows7 from her HP Pavilion G7-1053SF notebook and installed Ubuntu 10.04 (Linux 2.6.32-31). The notebook apparently uses the Intel HM55 chipset.

The only issue she has is that the notebook loses the wlan connection.

Does someone know what the issue is, and how to solve it?

Thank you.

Thanks. I didn't think of trying Google to translate infos :-/

Apparently, the Intel HM55 is just the video chipset, while the wlan part is provided by Broadcom.

"lspci -knn" seems to say it's a RaLink 5390:

I have no experience with RaLink cards, but I think I found something here(Ubuntu Forums). I don't know if messing with the wireless switch will help. Maybe if you open Jockey, you can select an alternate driver for your card. It's usually somewhere in the System menu, just look for something having to do with drivers. If that doesn't work, we'll have to disable NetworkManager and try to manually configure wlan card (real pain)

Out of curiosity, once a module/driver was installed manually (ie. without going through Ubuntu's Synaptics GUI package manager), what happens when I use Synaptics to upgrade to a newer kernel: Will the next Linux kernel still be able to load and run the Ralink wifi module, or must I run "make install" after upgrading the kernel so that I add the module to that new kernel?

Thank you.

Oops, sorry for the delay. When you upgrade your kernel, it would be a good idea to compile the module against the header files for the new kernel, but only if that module no longer works. If a new version of the module is released, then you should read the release notes to determine if that version is compatible with your kernel version. If they are, copy the module file to a safe location, then go through the process of building the new module.

Thanks for the info, but what I was wondering, is what happens when the kernel is upgraded through Synaptics: Must I recompile/reinstall the module, or will it still be loaded?
Since a module is compiled against the kernel headers, I suspect upgrading the kernel will prevent loading older modules that haven't been recompiled.
