no connection after switching between wired and wireless network

[Adam Niedling]

Binary package hint: network-manager

I'm using up-to-date Jaunty. If I start using my laptop in wireless mode and I turn of wifi and plug in an ethernet cable I won't be able to reach the internet anymore with firefox/epiphany/pidgin/skype/etc. This is also true vice versa, if I'm using a wired connection I can connect to a wireless network but applications won't be able to reach the internet. The only thing is working is ping. I can ping websites.

$ apt-cache policy network-manager

Firefox is just loading and not doing anything after switching to different network. (betöltés=loading)

Yes, I can still reproduce with up-to-date Jaunty.

Still an issue in Karmic.

This is not an issue anymore in Lucid.
