poor wifi connection -- Atheros QCA6174

[Jan-Jan]

1st off, thank you very much for this respin!!! Your boot cd works great.

However, I previously had Manjaro installed on my laptop and my wifi network worked properly throughout my house and my connection remained great. Now with Ubuntu my network works poorly unless I sit right next to the router. I've tried passing nohwcrypt=1 to the driver, disabling IPv6 via the network interface, and even setting the REGDOMAIN.

Is anyone else experiencing problem? What should I try next?

I'm posting it here because I thought the solution should become part of this respin.

lshw -C network results in

I have access to a Dell XPS 13 with Ubuntu and the same card, that works great.

  *-network

       resources: irq:137 memory:dc000000-dc1fffff

The only difference I see is that the driverversion of ath10k_pci. This made me look at the kernel versions: the XPS 13 is on 4.15.0-45-generic (Ubuntu 18.04.1 LTS) and the XPS 15 on 4.19.0-041900-generic (Ubuntu 18.04.2 LTS).

I'll be trying to add an older kernel to the XPS 15 to see if that works better.

I've booted into 4.15.0-45-generic on my Dell XPS 15. The problem persists... :-(

Have you found a fix for your issue? Have you tried to run the "update.sh" script?

[Jan-Jan]

Hi @stockmind, I've been unable to fix my issue.
I've upgraded to 18.10, with no discernible improvement.
I've run update.sh script, with no discernible improvement.

What kernel are you using right now?
