GL-AXT1800 (Slate AX) no WAN-side IP assigned over Ethernet, over WLAN working fine

I have the following situation:

  1. Slate AX ( is connected over Ethernet (WAN Port) to a Huawei HG8245H5 ( router. Slate is not able to get an IP address as a DHCP client.
    Setting the IP manually on Slate to I am able to ping the from the Slate, but no internet access possible.

  2. Slate AX is connected over WLAN (WAN as Repeater) to the same router. Everything is working fine.

The Slate worked before with two different AVM FritzBoxes over Ethernet without any problems.

Any ideas why it is working over WLAN but not over Ethernet?

Can you connect PC to the Ethernet port and get IP?

You mean to the Ethernet port of the router? Yes, every device (PC, switch with further PCs and a Set-Top-Box) gets an IP.
I tried also different ports and different cables.

Sorry I mean connect to Huawei HG8245H5 directly.

Every other device connected to the Huawei router ist working. Only the Slate is not working.

Sorry for late reply. I have no clue. Did you find something?

Unfortunately I did not find anything. I tried it with an another router and it worked.
Normally I would say it is related to the Huawei router, but why is it working over WLAN and not over Ethernet?

I will try to do further analysis, when I am again at the place with the Huawei router.
