FS#1991 - TP-LINK TL-WR1043ND v2 bad wireless perfromance

openwrt-18.06.1 (release)

TP-LINK TL-WR1043ND v2 set as AP bridge
1Gbps ethernet connected to a desktop - iperf3 server (iperf3 -s)
Xiamomi Mi Note3 connected wireless (same room, approx 6m from the router) - iperf3 client (iperf3 -c <IP> -i 1 -t 60)
Also other clients are connected, but not doing any large transmissions. Some are one or two floors below the room with the router.

Measured bandwidth is around 70Mbps, but fluctuates. Rarely hits 100Mbps, occasionally drops to 0 for several seconds.

For reference, I tested with an old CC (pre release), starting with CC r44455 (that’s what I had on an older TP-LINK router) and up, until commit [mac80211: update to wireless-testing 2015-03-09](

Measured bandwidth is around 120Mbps.

Tested several commits in CC after the commit mentioned above, but the speed never reaches levels before that commit.
Tested releases CC 15.05, 15.05.1, LEDE 17.01.6, Openwrt 18.06.1 with the same bad performance.

I realize there must have been many changes since 11.3.2015 and the state of the drivers at that time may no longer be reasonably comparable to the recent state. I’m also not sure if this is still the right place to report such a bug (if it is a bug) or I should report it elsewhere (where?).

If you think it makes sense to find the cause, I can provide data or test, but at this point I don’t have a clue what to look for or where to start.
