Hi :) Got a Lenovo T400 laptop with an Intel 5100 wireless card, lspci: 03:00.0 Network controller: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection Which was working until I updated my system.

I have been reading the forums and found these 2 links: http://bbs.archlinux.org/viewtopic.php?id=77416 seems that okczenaj solved the issue reinstalling his system and installing: iw iwlwifi-5000-ucode wireless_tools packages http://bbs.archlinux.org/viewtopic.php?id=62532 seems iggyst00ge solved his issues by dropping Arch Linux 64 Is there any way to solve this issue without having to reinstall my laptop? As I said before, my wireless was working until I updated. Don't know for sure which package broke wireless connectivity. TIA Rafa -- "We cannot treat computers as Humans.
