Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.11 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

Restarting the network-manager sometimes fixes the problem. dmesg | grep ath shows the kernel log. The system finishes booting at 12.x seconds with no wifi connections. Network-manager is restarted around 3x seconds and connection is established around 78.x seconds. Then firmware crashed at 624 seconds, followed by a successful recovery. At 915.x seconds a suspend is attempted, followed by a restart of network-manager scheduled by systemd. Connect was lost. Launching Wicd network manager recovers the connection, but the network-manager shows nothing. Ubuntu: 17.04, kernel: 4.10.0-19-generic Firmware: I tired the qca firmware at https://github.com/kvalo/ath10k-firmware/tree/master/QCA9377/hw1.0 . all three files have the same md5 as the one installed by default.
