I think I have the same problem with an SMC wirelss PCMCIA cart using module atmel_cs.
I test the laptop and the card with the Breezy Live CD, and it worked fine. Then I installed Dapper and while the interface is showing in the network manager, it seems not abble to connect. I test an USB wireless adpatator and it is working fine. By the way, I found a scenare to make my PCMCIA working with Dapper. Here it is: -Plug the PCMICA wireless card and the USB wireless adaptator -Configure everything as it should be in the network manager -Remove the PCMCIA card -In terminal do: sudo modprob -r atmel_cs -Plug the PCMCIA card -In terminal do: sudo modprob atmel_cs -Remove the USB adaptator Then the PCMCIA continues to work fine. I have tried the same scenario without the USB adpator part, but it is not working.... -- [dapper regression] orinoco_cs PCMCIA wireless card no longer hotplugs with Thinkpad T22 https://launchpad.net/bugs/43194 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
