I have the same card and experience similar problems. For me downloading
is normal, but uploading is significantly slower.
I inspected with iperf3 to a ubuntu server on my network.
It is interesting to note that increasing the parallel streams increased and
eventually saturated the network throughput.
The command 'iperf3 -c myserver' yielded:
[ 4] 0.00-10.00 sec 15.3 MBytes 12.8 Mbits/sec 0 sender
[ 4] 0.00-10.00 sec 15.3 MBytes 12.8 Mbits/sec receiver
And the command 'iperf3 -P 40 -c daanserver' yielded:
[SUM] 0.00-10.00 sec 277 MBytes 232 Mbits/sec 91 sender
[SUM] 0.00-10.00 sec 275 MBytes 231 Mbits/sec receiver
