<goose> does anyone know why ubuntu will detect wireless networks, but not connect to them?
<Johnny> goose, i had a similar problem it has something to do with nm-applet and network manager conflict i think
<Johnny> cant remember what though
<goose> Johnny, do you remember how you fixed it? I have no idea what nm-applet is
<Johnny> i dont goose i sold that laptop to a friend sorry
<goose> damn.. it originally worked straight off the install, but when I installed wifi-radar, it stopped working
<wbmj> goose: to use wifi-radar you need to edit /etc/interfaces
<goose> wbmj, I tried removing wifi-radar and it still wouldn't connect after I got rid of it
<goose> wbmj, detects fine and dandy, just doesn't connect
<Johnny> does it ever connect goose and then just stop suddenly?
<goose> Johnny, nope, doesn't assign me an IP address at all
<wbmj> goose: Do the connections have an icon next them
<goose> wbmj, not following you. what do you mean?
<wbmj> goose: left click on the nm-applet... the dropdown menu should list available connections
<goose> wbmj, it only says "Manual configuration"
<wbmj> goose: open System > Administration > Network and set your wireless connection to roaming
<goose> wbmj, ok, done. How can I check to see if I have an IP assigned to my wireless?
<wbmj> goose: now go to the nm-applet and see if you have a list of access points
<goose> wbmj, yes, I do. Only one, the network I'm hard wired into right now and trying to connect to wirelessly.
<wbmj> goose: laptop?
<goose> wbmj, yep. I'm 30% done downloading a 700 mb file, so I'm a bit hesitant to unplug the ethernet and test it
<goose> wbmj, is there a terminal command I can execute to see if I have an IP assigned to my wireless?
<webman> goose: ifconfig -a will show all interfaces
<wbmj> goose: ok when you finish download disconnect the hardwire and logout/in........should update nm-applet listings

jeg forstår ikke helt - er du en af de to, der diskuterer her?

og er dit spørgsmål, om det teoretisk set er muligt, at wifi-radar kan finde et netværk og ikke connecte? for så er svaret da ja. men er det så dit problem eller hvad? hvad er det egentlig, du gerne vil vide?
