I have a Broadcom Wireless Network Adapter and I had all sort of problem with the standard driver, Broadcom STA Wireless driver or wl that the module is called.
To identify which Broadcom chipset you have. Run:
To identify which modules (driver) you are using (running):
I had the STA or wl module running. To remove all possible Broadcom modules.
And to really remove the default STA or wl module, also remove the debian package. After the purge, that remove configuration files as well, I double run apt-get with remove autoremove, which will remove unused package and finally I run clean, to clean the apt-get cache. All for precaution.
Now you must test which driver/module that suites you best. I started with the b43 driver/module.
To load the new module/driver.
Now test you installation, if successful reboot and double check, that everything is working correctly..
Other possible driver are b43legacy package firmware-b43legacy-installer and LP-PHY package firmware-b43-lpphy-installer.

For many people the first thing they have done after installing Ubuntu, was to add the Medibuntu repository. But now it is dead. See announcement Here.
But what is the impact? Not much. Ubuntu already offers most of the things that existed in Medibuntu and this only natural progress of the growth of Ubuntu.

The simplest way to manage network settings is to use the system-config-network tool or the non-graphical variant system-config-network-tui
To start, stop, status all our network devices
Other useful tools are:
|ifconfig||Display our network settings.|
|ping||Used for check network connectivity|
|route -n||Display routing and Gateway|
|traceroute||Display network routing to a host.|
|netstat -nr||Display open ports.|
Main network configuration file is /etc/sysconfig/network-scripts/ifcfg-<name>.
Local routing for e.g. localhost, but also for static routing.
Main routing configuration file. Any changes will be overwritten, unless disabled in above sysconfig network-scripts with PEERDNS=no.
- network-scripts: /usr/share/doc/initscripts-<version>/sysconfig.txt
