I recently bought VIM3 Basic.
But problem is that wired network doesn’t work properly.
It should be 1Gbps.
But Download speed is just around 3Mbps , Upload speed is OK (1Gbps)
I tested with iPerf3 and 3 different category 5e LAN cable which is OK for other device.
and tested on VIM3_Ubuntu-server-bionic_Linux-4.9_arm64_EMMC_V20191231 and Armbian_20.05.1_Arm-64_buster_current_5.6.2_20200408
Here is test log

iperf Done.
Are you sure that the converter of your PC’s Ethernet port can reach 1Gbps ？
Yes. I tested with another khadas board(VIM3 PRO) and exactly same cable and converter,
it was ok( around 930Mbps)
Frank

@mokuzin So just this board can’t ?
Yes
I think it could be hardware fault
Frank
6
Our hardware colleagues @kenny will help you .
is there something different firmware or setting
between VIM3 BASIC and PRO?
Frank
8
@mokuzin NO, It’s same about WiFi and Ethernet .

Hi Mokuzin
could you help to
- try VIM3_Pie_V200319 this firmware to check again?
- post some photo to check here:
thanks
I returned my VIM3 for refund
maybe you can test it from SmartFly where i bought
