I have the same Wifi Card:

*-network
   description: Wireless interface
   product: QCA6174 802.11ac Wireless Network Adapter
   vendor: Qualcomm Atheros
   physical id: 0
   bus info: pci@0000:3c:00.0
   logical name: wlp60s0
   version: 32
   serial: 9c:b6:d0:10:37:f7
   width: 64 bits
   clock: 33MHz
   capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
   configuration: broadcast=yes driver=ath10k_pci driverversion=4.14.78-041478-generic firmware=WLAN.RM.4.4.1-00079-QCARMSWPZ-1 ip=192.168.1.68 latency=0 link=yes multicast=yes wireless=IEEE 802.11
   resources: irq:138 memory:dd200000-dd3fffff

It’s using the same driver but compiled for an older kernel:

driver=ath10k_pci driverversion=4.14.78-041478-generic firmware=WLAN.RM.4.4.1-00079-QCARMSWPZ-1

Your firmware is also identical:

firmware=WLAN.RM.4.4.1-00079-QCARMSWPZ-1

To answer your question, AFAIK there isn’t a newer driver you can use.

You can use this command however to check for errors:

$ lspci -nnk | grep -iA2 net; dmesg | grep ath10k

Please Update your question with the results of:

lspci -nnk | grep -iA2 net; dmesg | grep ath10k

There is a four year old on-going bug report with 350 posts. It has solutions for compiling the latest ath10k_pci patches: Atheros Qualcomm Killer N1525 Wireless-AC [168c:003e] is not supported
