I had the same problem and unsuccessfully tried: 1. the linux-firmware package from yakkety 2. kernel-4.6.3-yakkety 3. kernel-4.7.4 4. sudo modprobe rt2800pci nohwcrypt=Y 5. sudo iw reg set NL
While the newer kernels seemed to alleviate the problem, they didn't fix it. Then I reverted all the previously listed changes and turned the card's power management off. That fixed it. However, since power management would turn on every time it would connect to a network, I made a simple NetworkManager script, that you can find at http://askubuntu.com/a/825976/349291 The following are some relevant info about my system: $ uname -a Linux precision390 4.4.0-36-generic #55-Ubuntu SMP Thu Aug 11 18:01:55 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux $ iwconfig wlp5s5 IEEE 802.11abgn ESSID:"<edited>" Mode:Managed Frequency:5.18 GHz Access Point: <edited> Bit Rate=270 Mb/s Tx-Power=20 dBm Retry short limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=42/70 Signal level=-68 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:133 Invalid misc:781 Missed beacon:0 $ apt list linux-firmware Listing...
