Normally this is handled by NetworkManager. Clicking on
the NetworkManager icon (somewhere in the top panel) should show you a
list of access points.
If NetworkManager doesn't show anything then perhaps wireless is turned off?
Otherwise dmesg might show you some error message related to wireless.
I found the NetworkManager icon. (It is not what I found when Googling on
the internet,
two terminals, but in stead a spreading wave front. But it summons similar
menus and
dialogs as they sy,so I suppose it is the one.)
Problem is that the menu is pops up does not list any wireless network.
Just a wired
network, which does not work, because I have no cable.
I have a hardware button to turn the wireless adapter on and off, which
also lights a LED.
under Ubuntu 8.04 this button was inactive, though: the LED was never on,
and I was
always connected. Now the LED reacts to the button. But even if it is on, I
don't get
any wireless item in the NetworkManager menu. I tried the configure VPN
entry to
summon a dialog which also had a tab for adding and editing wireless
connections.
I don't know how to use it, though. It asks for an SSID a BSSID and a MAC
address.
I have no idea what to put there. Is SSID the name of the network you want
to connect to?
(I called that wlan@thuis on the wireless router.) The MAC address is of my
wireless card?
I have no idea how to approach that card. I found something about ifconfig,
but it seems
to need a device name. I tries 'lsmod' (also because it was recommended
somewhere),
but I do not find the name of my wireless card (a TNET1130) anywhere in its
output.
