Continuous Network Connectivity Between Sessions Problem

Hey All,

Well, I thought I had everything ironed out, but I've run into another problem. This one isn't crippling, it's just a little annoying.

After finding my ESSID and MAC address of my router from iwlist wlan0 scan, I populate the Wireless Tab under "System-Preference-Network Connections, and I connect without a problem.

However, if I shut down my laptop after I'm done, and then boot it back up next time I want to use it, I have to delete and re-create the wireless connection under Network Connections in Ubuntu for it to work.

I read some literature online and the general consensus was that Most home networks broadcast in ESSID, which means it is hidden, and unless you plan to unhide your SSID (i.e. turn off SSID broadcasting on the router, you will pretty much have to do this every time

I can tell you that my router does not like to work unless SSID broadcasting is enabled, so I guess my question is if I am going to have to re-create the entry every time I begin a new session, or if there is a way around it?

One way that you can do this is to put the information in the following file:


An example might look like this:

auto lo
iface lo inet loopback

iface eth1 inet static
wireless-key <wireless_key_here> restricted
wireless-essid <essid_here>

auto eth1
Where <wireless_key_here> would be your key and <essid_here> would be replaced with your essid. This depends on what kind of security you are using. For more information you could take a look at the manual page with the following command:

man interfaces
