A more reliable test of performance would be to use iperf against a machine with a wired connection to the same network, if possible, and make sure that you're using the same network with all kernels. If it's a network with multiple access points then you could get different results though depending on the AP you happen to be connected to, channel, etc. > Firmware is 22.24.8.0. > > With this versions I don't get an strange phenomenon where "System Load > Indicator" showed equally separated peaks of infinity connection > download speed. > > Is there a method to know if there was a disconnection? I mean some kind > of "dmesg | grep xxxx" You could check /var/log/syslog for the string "disconnect", e.g. 'grep -i disconnect /var/log/syslog', but that could contain logs from prior boots so you could get false positivies. The particular problem I was seeing (disconnection due to beacon loss) result in messages like this: wlan0: CTRL-EVENT-DISCONNECTED bssid=xx:xx:xx:xx:xx:xx reason=4 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1349572 Title: Wireless network disconnections on Dell XPS 13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1349572/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
