Hi, I've other problem that related to the Ethernet port recently after I upgraded ISP speed from 100Mbps to 500Mbps (down&up).
I manually turn off WiFi and make sure it fully run on my Ethernet port, then run speed test but only can get around 200Mbps (download) & 350Mbps (upload), very weird because my laptop can easily get 500Mbps for down&up.
In order to get full speed on my Q10 Pro, I need to do following thing:
without switch off Q10 Pro, I try to unplug the network cable from Q10 Pro and plug-in back again, without do other thing, with same speed test method, then I can get 500Mbps

But I need to do this every time I turn ON Q10 Pro which is not make sense

I reboot Q10 Pro and retry again and again, the only way to get full speed is unplug the network port and plug-in again only can get full speed

Is there something on my Ethernet chip itself or something bug? By replaced with other network cable still no help

I really hope someone or
futeko can help me on this.
