Introduction


This page is a list of important config files used with wireless networking.

Files

/etc/network/interfaces

This file stores networking interface settings.

IconsPage/tip.pngNetwork Manager cannot manage any interfaces that are named in this file. Network Manager has been the default way of managing network connections since Ubuntu 8.10 (Intrepid Ibex)

Other Resources

/etc/resolv.conf

This file stores Domain Name Server (DNS) settings including nameserver addresses, local domain names/search server addresses and some other advanced settings.

/etc/modules

This file lists some of the modules that will be loaded into the kernel at boot-time. If a driver won't load at boot, you can add it to this list so that it does.

/etc/modprobe/

To enable specific configuration options for a driver create an appropriate config file in this folder eg. config.conf or [drivername].conf and add the options you want to set in this file.

notes

With the release of Ubuntu 11.10 and kernel 3.x.x some wireless drivers now no longer need 11n_disable and 11n_disable50 options. Theses options may actually cause the driver to fail to load. Check the /etc/modprobe.d/ folder for config files that contain option reference to your driver, for example

options iwlagn 11n_disable=1 11n_disable50=1

These options can be found in config.conf or [drivername].conf file eg. intel_11n_disable.conf or awlagn.conf.

/etc/modprobe.d/blacklist

If you don't want a driver to load at boot you add it to this list. Usually this is used if you have a driver conflict and/or you want to make sure a specific driver is used. Note: this method will not work unless the diver is a LKM (loadable kernel module) If driver/module was compiled into the base kernel, it will still load if blacklisted.
