Is there any potential = problem with enabling sqm with cake on both eth0 (wan) and wlan0? The = reason for doing this is that if I only do shaping on the wan interface = I still get bad uplink bufferbloat on wifi. I assume this is because the = bottleneck in this case is actually the wifi and the bloat is in the end = device (laptop, phone, etc.). By shaping to a rate lower than the wifi = rate, the bloat disappears. Is there any better way to accomplish this = than to enable a second sqm instance on wlan0 if I don't want to = sacrifice speed for wired devices? Aside from fixing the end device so it isn't bloated in the first place, = I think you have a reasonable solution there. You might only need to = limit the ingress rate on wlan0, if your router's wifi stack is = debloated. - Jonathan Morton
