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.

Code: Select all

lsmod|grep ath
ath10k_pci             47418  0 
ath10k_core           325711  1 ath10k_pci

cfg80211              632335  3 ath,mac80211,ath10k_core

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:))
