Wifi: DHCP timeout

Hi peoples!

I've got a new arch install on my macbook pro 7,1 and it seems the wifi won't connect unless the encryption's set to WPA.

Here's a wicd log from a connection to a WEP network

I must admit I'm pretty much lost... I don't really know where to start to fix this problem

Re: Wifi: DHCP timeout

Welcome to the forums, velxundussa.

Just a hint: Please use [ code ] tags around listings instead of [ quote ] ones. This will display display monospaced text in a scrollable window which is far better suited esp. for long listings.

Re: Wifi: DHCP timeout

oh, thanks for the tip bernarcher.. I did search for a list of tags but couldn't find it so got the first one that I knew that'd work ^^'

Anyway, I did try to change to dhclient without any changes on the problem, but the log is indeed a little bit more talkative:

edit:
the change to dhclient, however does change the fact that now I can't even connect to WPA networks...
Changed back to dhcpcd. Here's a log of a successfull connection to the very same network with the security changed to WPA2 personnal

Re: Wifi: DHCP timeout

I've never been good at reading wicd logs, but there seems to be a conspicuous lack of wpa_supplicant messages*.  Doesn't wicd use wpa_supplicant to connect to WPA(2) networks?

How you tried manually connecting?  Do you get errors then?

*edit: now I see the message about it stopping wpa_supplicant ... but it shouldn't be stopping, it should be starting!

Re: Wifi: DHCP timeout

Well, I don't think wpa_supplicant is in fault here since the only wifi connections that does work are the WPA ones!

I think that when the log says that it's stopping wpa_supplicant it means that it resets it's parameters to setup the new connection
