Dell XPS 13 9360 : Ubuntu Wifi disconnection
Raw
xps13.md

I encounter wifi disonnection problem on a Dell XPS 13 9360. Here is the solution I used to fix this bad behavior.

Which wifi card version is installed ?

lspci | grep -i net

3a:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)

Here, we have the QCA6174 model.

Retrieve last driver version on :

https://github.com/kvalo/ath10k-firmware

Replace wifi firmware firmware-6.bin

cd /lib/firmware/ath10k/QCA6174/hw3.0
sudo cp firmware-6.bin firmware-6.bin.backup
sudo cp <downloaded_file> firmware-6.bin

Update path using your wifi card model : /lib/firmware/ath10k/<wifi_card_model>/hw3.0

Reload drivers

sudo modprobe -r ath10k_pci ath10k_core
sudo modprobe ath10k_pci
sudo modprobe ath10k_core
