Is the module ath10k_pci listed in lsmod?
Do you see any errors/hints in dmesg?

I just installed CentOS 7.7 on a machine using this WiFi card and I am experiencing the same issue.
My card is listed under lspic and lshw:
Code: Select all
$ sudo lshw -C network
*-network
description: Network controller
product: QCA9377 802.11ac Wireless Network Adapter
vendor: Qualcomm Atheros
physical id: 0
bus info: pci@0000:03:00.0
version: 31
width: 64 bits
clock: 33MHz
capabilities: pm msi pciexpress bus_master cap_list
configuration: driver=ath10k_pci latency=0
resources: irq:134 memory:b4200000-b43fffff
And the drivers are shown here from lsmod:
Code: Select all
$ lsmod | grep ath10k
ath10k_pci 47418 0
ath10k_core 325711 1 ath10k_pci
ath 33542 1 ath10k_core
mac80211 718956 1 ath10k_core
cfg80211 632335 3 ath,mac80211,ath10k_core
Does this information shed light on any issues? I can give more output if needed.

Same here. If anyone knows the solution, please share. My laptop is Lenovo Ideapad 330, wifi card also Atheros QCA9377. Everything worked fine before latest update.
edit:
Thank you Dennis. I didn't see your post yesterday. Removing firmware-6.bin and notice_ath10k_firmware-6.txt worked! Yeaaah:))
