Network Card Determination

From ubermix Wiki
Jump to: navigation, search

Driver problems are relatively rare with ubermix, but if you are going to have a driver problem, more often than not it will be with a network card - usually wireless. When searching for help, online or otherwise, it is always useful to know exactly what wireless chips your device actually has in it. Before you go to search for help, be sure to first determine exactly which wireless chip is in your device by opening a terminal and typing the following:

lshw -C network

When you run the command, you should see a ton of useful information that looks something like this:

  *-network

When searching for solutions, always use the "product" part and "Ubuntu" or "Linux" in your search string. If you see a driver listed (like "iwlagn" above), include that too. So, for example, if I was having problems with my wireless, based on the listing above I would search for:

Centrino Wireless-N 1030 Ubuntu Linux iwlagn

and look for results related to my problem. If you can't find what you are looking for or need a little help deciphering the results, you can always shoot me an email at jnetman1@ubermix.org and I'll do what I can to help you out.
