Hi Toke,
Yes, I run on my laptop(Dell LATITUDE E5440 + QCA6174 PCI wireless card) in open air environment,
Kernel is 4.18.0-rc2-wt-ath+ #2 SMP which is built myself.
The mac80211.ko/ath10k is built with the 2 patches.
192.168.1.7 is another device(PC installed with 4.4.0-116-generic #140~14.04.1-Ubuntu)
