Hello, I noticed strange issue after updating from chaos calmer to the new lede/openwrt. When wifi is disabled, I get about 90mbit down speed (from 100 possible), when I enable wifi, wan to lan speed drops to 65mit I downgraded back to chaos calmer and it is fast again no matter if wifi is up or down. No wifi station was connectected during the tests.
I can see the same behavior on routers tp-link wr841n v10 (QCA9533-BL3A) and wr842nd (QCA9531-BL3A). I believe the same problem exists on different 100mbit routers with atheros. On wr1043nd (QCA9558) which has gigabit ports I don't see this issue. I don't think it's CPU problem, wr841n and wr842n has fast 650MHz CPUs and load is less than 10% during speedtest tests on both CC and lede. NIC % load corresponds actual measured speed.
I believe designated driver was ok too, so it must be some new "feature" in lede. Someone noticed this too? May I report it as a bug?
