I am using WICD as my wireless network manager and it works connecting to a network for the first time. But when I resume my laptop from hibernate or standby, WICD will not reconnect to the network and gets stuck on obtaining an IP address. And if I try to change networks without hibernating I get the same problem.
Also, I notice that the network name is stagnant. I connect to multiple wifi networks a day because of school. When I leave my "home" network and connect to my "school" network WICD still says "Homebtaining IP address" even thought it should say "schoolbtaining IP address."
My thoughts are that it isn't releasing the network properly and when its trying to connect it can't because it still thinks it's connected. The only solution I have found is to restart my laptop every time I want to connect to a new network, or shut down every time I am done using my laptop, which is a major inconvenience. Please help.
Here is what I am using:
HP tx2000
Broadcom BCM4322
Ubuntu 10.04
WICD 1.7.0
"I am using WICD as my wireless network manager and it works connecting to a network for the first time. But when I resume my laptop from hibernate or standby, WICD will not reconnect to the network and gets stuck on obtaining an IP address."
If you issue the command without the quotes "/etc/init.d/networking restart"
that will restart your network.
"I cannot switch between networks while the computer is on"
I'll assume you are getting an IP address issued via DHCP. So, if you were using Network-A and then hibernated and then wanted to connect to Network-B you should be able to use your "WICD as my wireless network manager" *** AFTER ISSUING *** "/etc/init.d/networking restart" to connect.
Just wanted to say I am having the exact same problem with wicd and the bcm4322 on debian. The solution of reloading the "wl" driver also worked for me.
I have the same problem, too, when waking from suspend. The only way I can correct it is to disconnect from all networks, change the DHCP Client in Preferences-->External Programs, then reconnect again... Sometimes that works, and sometimes it doesn't...
No one has found an automatic fix to this problem? It appears to have something to do with the DHCP client. Thanks
I have a similar problem, but that happen to me also when the access-point goes down and goes up again, and i want to reconnect to it. I think the bug is either on the wl module, or in the wicd program, because, it seems (at least from what i have seen), that wicd goes through the hand shaking without receiving an acknowledgement.
I have had similar problem when I had my Compaq laptop which had a broadcom wireless card on it. I believe the way I got around that was for the system to run a small script to stop the wireless interface, unload the wireless driver and then go to sleep. When it resumed from sleep, it would reload the wireless driver, and re-enable the wireless interface (Connect to the AP and issue a DHCP request).

The problem has self-healed. Only thing that has been changed, is removing 'connect automatically' from the networks concerned. But that's unconfirmed as of now.
