Ubuntu Networking quirk

RyanHall85 · 04-09-2009, 06:51 PM

I'm running Linux Ubuntu, and when I start up my system, there is no internet connection. I have to right click up top where it show my connection (or lack there of), edit settings, then un-check the "system setting" box. Then the connection connects immediately. What would cause this, and how can I un-check that box permanently?

Wireless using Linksys WUSB54GS
Ubuntu 8.10

auto lo
iface lo inet loopback

Are you using wireless encryption? This assumes you are not:

Type ifconfig in a terminal to find the name of your wireless interface.
Suppose it is wlan0

Make the interfaces file look like this:

Code:

auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet dhcp

Then reboot or do sudo /etc/init.d/networking restart

Of course.
Are you using WEP WPA or WHAT ?

I'm using WPA.
Here's my interfaces file:

Code:

auto lo
iface lo inet loopback

# My wireless interface ( which is called eth1 )follows
auto eth1
iface eth1 inet dhcp
# Note my passphrase in the next line has no "funny" characters or spaces
wpa-passphrase MyPassPhrase
wpa-ssid TredsNetgear

Make yours look similar
Then try sudo /etc/init.d/networking restart

Yeah I'm using WEP 10 hex digit

You might as well not bother with "encryption" then - search the web for "Crack WEP"
Switch to WPA.

OK wellc an you tell me how it would look if it is wep? Is it the same as what you had posted above except wep instead of wpa?
