I've finally got around to testing on lucid live cd. The issue is NOT present and wireless works fine after using jockey to install driver. This confirms that this a regression.
Some observations: 1. /proc/modules shows that the dell-laptop module is indeed loaded: dell_laptop 7941 0 - Live 0xffffffffa0065000 2. rfkill list does not list any devices however. Here is the output of modinfo dell-laptop on lucid: $ modinfo dell_laptop filename: /lib/modules/2.6.32-24-generic/kernel/drivers/platform/x86/dell-laptop.ko alias: dmi:*svnDellInc.:*:ct8:* license: GPL description: Dell laptop driver author: Matthew Garrett <m...@redhat.com> srcversion: 104553967ECAF17A9FB03B3 depends: dcdbas vermagic: 2.6.32-24-generic SMP mod_unload modversions -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/701259 Title: dell-laptop module hard blocks wifi on Dell Vostro 1520 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
