You didn't provide any dmesg out but I assume this has a WCN7850 chipset. Please provide output from 'dmesg | grep ath12k' so that we know what firmware etc you are using. > While generally stable, I'm encountering two issues: > > 1. High ping latency/jitter: > - ath12k: 3.5ms to 55ms (40ms jitter) Is this from network to ath12k or from ath12k to network? I recommend testing both. Usually Power Save Mode causes latency, have you tried disabling that? > 2.

Once there is something to test we will announce it in this ath12k list. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
