Re: Issues with TP-Link UE300

Hi,

This seems to work much better!
Transferring files via NFS, I could sustain from 118 to 148Mbps.

Kernel says:
ure0 at uhub0 port 15 configuration 1 interface 0 "TP-LINK USB 10/100/1000 LAN" rev 3.00/30.00 addr 5
ure0: RTL8153 (0x5c20), address d0:37:45:xx:xx:xx
rgephy0 at ure0 phy 0: RTL8251 PHY, rev. 0

ifconfig says:
ure0: flags=808843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,AUTOCONF4> mtu 1500

usbdev says:
addr 05: 2357:0601 TP-LINK, USB 10/100/1000 LAN
super speed, power 64 mA, config 1, rev 30.00, iSerial 000001000000
driver: ure0

iperf3 says:
[ 5] 0.00-10.00 sec 618 MBytes 518 Mbits/sec sender
[ 5] 0.00-10.13 sec 618 MBytes 512 Mbits/sec receiver

Thank you very much.
