[S922X] X88 King

Other than removing the heatsink, or asking others users over at somewhere like Freaktab if anybody has done a teardown, the other option is to go to the stable version of Android that worked and run some basic speed tests over ethernet.

Results will be vastly different between 100 and 1000Mbps
.

It is under heatsink, i saw on photo also

My router asus ac56u see it (only with android) as gigabit device. In coreelec is no log from box to router. Problem must be in driver of coreelec.

Regardless of what anything sees it as, there is no substitute for actual testing to get real results to confirm something that just believe it.

But it is depend on provider. I have max 20/20 from provider of my internet.Here is maybe usefully information :

For eth is id in log from dmesg: meson6-dwmac ff3f0000.ethernet eth0

Please use a terminal client where you can copy/paste the output to the forum.
Can you please make a latest dump of the dtb with last firmware?

Just use this cmd when booted to CE:
dd if=/dev/dtb | gzip > /storage/downloads/dtb.img.gz

On Android you have gigabit speed?
You can test it by iperf.

Yes is going with good speed and as gigabit. I have only 20/20 speed of my internet provider, but going as usually with gigabit device. I dont know, which terminal know export log from cmd dmesg.dtb.img.gz (50.7 KB)

Yesterday i take photo also from remote control chaneels, maybe it help for better bl grabing from this device for turn on/ turn off.

Please try this dtb:
g12b_s922x_x88_king_rev_a.dtb (70.0 KB)

Move your boot media to a PC and rename this file to dtb.img and copy it to COREELEC partition.

I tried on stabil new coreeelec, and also on nightly with your dtb. Both cases was unsuccessful. I tried dhcp, and static ip, but was no internet still.

Did you use a clean install? Make a new boot media from scratch and use my dtb, you should see Kodi wizard on first boot.
If booted and still not working please do dmesg|paste and five me the link you receive.
You need at least connected to WLAN. Please also connect LAN cable.
Also please do post the link you receive for your debug data using this guide:

Now i finally grab full dmesg from android with active dhcp on LAN. File is here (it was adventure):dmesg.log (169.8 KB)

And CE dmesg & log?

Crash log: http://ix.io/2pwI
System log output for: CoreELEC (official): 9.2.3: http://ix.io/2pwH

And dmesg|paste?

http://ix.io/2pwO

I do not see anything not working in your dmesg. Please post the output of:

dmesg | grep eth0
ifconfig

And please check if Wired is enabled in Kodi -> Settings -> CE Settings -> Network
Sample:

But, when not going lan, how i know send info from ifconfig ? I know connect to box only through wlan from pc with ssh terminal, but results would be impacted from wlan. For this situation we need tools for ifconfig direct in tvbox.
