Since it was an "n" issue I am now using the second one just for wifi (the first one hangs and has some other problems when I enable its wifi support, although only with linux). The wifi problem I reported has dissapear (it occurs once a week or so) after I upgraded the Lenovo W500 to 3.3.4-1~experimental.1 and decided to install compat-wireless-3.4-rc3-1.tar.bz2 from http://linuxwireless.org/en/users/Download/stable/#compat-wireless_3.4_stable_releases At first it was an small improvement (it disconnected 2~3 times each hour) but then I played with options and with options iwlagn ack_check=1 fw_restart=1 11n_disable=1 bt_coex_active=0 options iwlwifi ack_check=1 fw_restart=1 11n_disable=1 bt_coex_active=0 options cfg80211 ieee80211_regdom=EU it now disconnects once or twice a week. I think Olivier found the same solution for his problem in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=668547#40 The strange thing is that I've made the options change only in the Lenovo machine, the other machines disconnect once or twice too without any change. I should have tested more, but since it works and I do not know which is the problem I decided to stop making changes. Just let me know if you want me to test something else. If not I think bug should be closed.
