Hi All,
After noting that some music I was playing was skipping I've noticed that my CuBox i4-pro is only running at 100Mbps on the network. I believe the fault lies on the CuBox itself; here's the troubleshooting I've done to establish that:
- Other devices plugged in to different ports on my router get gigabit speeds.
- The CuBox, when plugged in to these other ports, still only gets 100Mbps speeds.
- The CuBox, with a different 1m Cat5e cable, still only gets 100Mbps speeds.
- The Cubox, with this different cable, plugged into another gigabit switch, still only gets 100Mbps speeds.
- My laptop, with this different cable, plugged into both the router and the gigabit switch, gets full gigabit speeds.
To confirm I should be getting gigabit, I checked the manufacturers page (SolidRun | Simple Robust Embedded Computing Solutions
Code
Ethernet: 10/100/1000 Mbps (*)
(*) Note that due to internal i.MX6 buses the 1000Mbps interface speed is limited to 470Mbps.
I've started looking at the CuBox and it seems to report that 100Mbps is the maximum:
Code

I tried setting the speed manually with:
but it just drops the connection and brings it back up at 100Mbps.
Any ideas?!
