Did anyone do this and can point me to the discussion in the archives? FWIW, from *a quick look* it seems the patch that was applied looks like a variant of the patch discussed in https://patchwork.kernel.org/patch/5784701/ One of the core Linux kernel network developers there answered the question "Does this look ok/safe as a solution to you?" with "Not at all."

Measured Rx 60Mbit/s and Tx 12Mbit/s with Ubuntu Windows 10 (1607) performs much better with on transmit side Rx 73MBit/s and Tx 62MBit/s using the same hardware setup. Same result with WPA2 disabled in unencrypted mode. Steps to Reproduce: 1. connect to Wifi 2. copy a large file from XPS 13 to a share on a 2nd system To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1692836/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
