Sorry, how did this get fixed?  Did your router get a firmware upgrade?

I've seen similar issues using a TP-Link Archer C<n> at a place while I was
on the road the last 6 weeks.  Was on a 100Mbit Ethernet internal (*)/external
and upload was "100%" while download was limited.

Doing a test between two wireless nodes I got about 200Mbit/s each way on
that box (which was faster than the ethernet).

The same laptops do 800Mbit/s on an AP at home.


That said, yes, download speeds are still a bit slower even on iperf in the
Lab, especially for TCP, but 40Mbit/s are sub 11n.

(*) the router fell over and restarted when I plugged a 2.5G ethernet in.
