More wifi issues - Qualcomm Atheros QCA6174 ath10k_pci

Question

My wifi has actually worked well until recently. I had put the files from kvalo/ath10k-firmware.git in /lib/firmware as per No Wifi in Qualcom Atheros - Ubuntu 16.04 - Acer Aspire E 15 and Problems with Qualcomm Atheros QCA6174 in Ubuntu 16.04 and others.

However, I still have major problems. Even plugging in a wifi dongle has issues, but one problem at a time - problem is definitely this device. The rest of the devices on my network are totally fine.

Running Ubuntu 16.10 on Acer Aspire V15 Nitro laptop.

Solution

I think you may be suffering from a couple different issues. I want you to reinstall the Ubuntu package linux-firmware as that may be more up to date than kvallo's github site

sudo apt-get install --reinstall linux-firmware

A recent change to network manager enables wifi powersave by default, to disable this do

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Reboot

I encounter this in Dell Inspiron 15, 5000series. using ubuntu 18.04

Is skip_otp=y helpful?

[jonathanbsyd]

Ok I found that simply deleting the ath10k folder in /lib/firmware then doing the reinstall of linux-firmware helped, as there must of been some of my mods that were causing issues. I'm not sure the powersave is an issue though, as I can't tell if it makes a difference. I think we're working again now. Thanks

@chili555 that might be taken care of in firmware now features wowlan,ignore-otp

@Jeremy31 Ahh! Thanks for the heads-up!
