Android and Ethernet

[rahlquist]

I tested speed using speedtest.net it showed terrible download speed

A suggestion for you and everyone else trying to test their Ethernet speed. Stop using 3rd party websites for benchmarking your Ethernet. At any given second any of the "test partners" that speedtest uses can hav an issue and you wont know. This will directly affect your speed testing. 

In a typical speed test with speedtest.net you can have issues from;
Test device (the pine in this case) 
Ethernet cable
All hubs, switches, or cables between you and the gateway at your ISP
Your ISP
The internet backbone
The server hosting the speed test for speedtest.net 

That is a lot of potential points of slow down, incompatibility and failure. 

Think in more scientific and controlled terms,  get something like iperf which is also meant to test speed. iperf 2.x runs on just about any platform. There are versions for Windows, Mac, Android, DD-WRT,  just about every linux variant out there. iperf v3.0 is newer and not backward compatible with 2.x. Its simple to use. I have it on my desktop and my laptop. If I want the desktop to be the server, I simply issue the command;

iperf -s

then on the client machine 
iperf -c <ip of the server machine>

so in my case that is 192.168.0.104

Here is my result

Code:

pine64user@debianpine64:~$ iperf -c 192.168.0.104
------------------------------------------------------------

As you can see my network is a bit busy as its the weekend and the wife is playing xbox and the kid is watching youtube. But I have eliminated a lot of other things that could have a negative impact.
