I've installed the kernel 4.2.0-040200rc6 and the problem disappeared: - no icmp packets are dropped, - dmesg does not report any dirty stuff related with rtl8821ae-0.
What I did: $ sudo dpkg -i linux-headers-4.2.0-040200rc6_4.2.0-040200rc6.201508092028_all.deb linux-headers-4.2.0-040200rc6-generic_4.2.0-040200rc6.201508092028_amd64.deb linux-image-4.2.0-040200rc6-generic_4.2.0-040200rc6.201508092028_amd64.deb $ sudo reboot $ uname -a Linux lapkra 4.2.0-040200rc6-generic #201508092028 SMP Sun Aug 9 20:29:59 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux $ dmesg > dmesg_4.2.0-040200rc6-generic.txt I attach dmesg_4.2.0-040200rc6-generic.txt Best regards, BemNum ** Attachment added: "dmesg_4.2.0-040200rc6-generic.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1482979/+attachment/4443470/+files/dmesg_4.2.0-040200rc6-generic.txt ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Description changed: Hello, The problem occurs at Ubuntu 14.04 LTS and Asus R510L notebook with RTL8821ae driver.
