I have a Lenovo Z70. Looks like it is using the Atheros QCA6174 and the ath10k drivers.
`dmesg | grep ath10k

I do get a wireless connection but it is weak and very slow. It’s usable, except for uploading, so I don’t want to do anything to make it stop working completely. I was looking here - [https://wireless.wiki.kernel.org/en/users/drivers/ath10k/firmware](https://wireless.wiki.kernel.org/en/users/drivers/ath10k/firmware) and it looks like there is a firmware update for the QCA6174. Would this help? Like I said, I don’t want to make the problem worse, not knowing what I’m doing.

Yes please try that newer firmware out like instructed on the website.

I may have done it wrong but after putting those files in the ath10k folder, I lost my wifi completely. I put the old ones back and got the slow wifi again. This is with the files I downloaded:

and this is when I put the old ones back (just curious, why is is renaming wlan0? :

I’ve seen a lot of people having trouble with this on Lenovos but I thought it was supposed to be working in the 4.2 kernel.
