Hi,
I've been using the Flint 2 for a few months now. I love the features it provides, but I bought it to replace a Wifi 5 router for better Wifi 6, obviously.
My wife works from home, so she's the first one who noticed the video chat stuttering and choppiness. This applies to Teams meetings, and Alexa drop ins with her dad.
I don't use much wifi so I shrugged it off for a while, but I've been dusting off my VR headset and I'm seeing serious lag spikes and stream tearing while using it wirelessly. These were never problems on my old router, other than it's limited processing power.
I'm already using cake SQM on my wan port, and my buffer bloat test results over wired are perfect. 9 ms ping, +0 +0 under load.
On wifi however, is another story. Ping can range anywhere from 10 ms to 350 ms. Under load it is regularly above +100 ms, more than often above +350 and I've seen as high as +1200.
I tried adding cake SQM to my wifi interface. It had some effect, but nothing close to acceptable for a video chat or voice call, and it's obviously not ideal due to varying speeds of wifi connections.
I found some folks online who suggest turning off WED, and lowering/tightening AQL thresholds. The problem is I cannot locate any of the config files necessary to do so on the Flint 2 using 4.7.7 firmware. There is no /sys/kernel/debug/ieee80211 folder for adjusting AQL. There is no /etc/modules.conf file to disable WED, and so on.
Clearly this level of wifi performance is unacceptable, and I can't figure out any other way to improve it. The only thing that is good about it is the max throughput when downloading large files, which easily saturates my ISP speed limit.
Any ideas would help.
