I assume the channel is equally vht/80 and the linuxkpi sysctl would not show anything else as before.

Since both directions=C2=A0were the same,= I'll keep it short.

Some things fixed a couple of issues I= 9;ve had.

1. I can now associate with a = 5g network even though a 2.4g is available. It also shows=C2=A0up in=C2=A0 = "list aps" output.

2. Using the same router that would only ass= ociate with TKIP, now AES-CCM works with no issues.=C2=A0

So two issues seem to be fixed.

Still a problem with poor download speeds. Using either Ookla S= peedtest or iperf3, I get excellent upload speed (100M on my Frontier conne= ction) but only 40M download. I get faster upload on my lan, but download s= till=C2=A0is limited to about 40M.
