After I set up my wireless network, I had to restart my computer before it would connect. I have talked to/read comments by, several other Ubuntu users who had to do the same thing. Why does this happen, and is there a way to connect a wireless network without a restart? Are we all just noobs and missing something obvious? I already understand the driver install process, but I just don't see why A restart seems to be necessary so often.

There are several methods you can use.

To bring down all network interfaces:

sudo ifdown -a

To bring all network interfaces up again:

sudo ifup -a

To restart networkmanager:

sudo service network-manager start

This also works for wired connections:

ifconfig eth0 down
ifconfig eth0 up
