First of all apologies for having being a confusing. It is absolutely clear to me that an AP only has a LAN interface and no WAN but I got mislead by the forum entries and started doing dumb things (moreover I really did not see the option to turn DHCP off). The AP now works flawlessly because I added eth1 to br0 (yes there are eth0 and eth1 despite there is just one physical port).

If I may, the AP has 32MB of RAM and not 4MB. I really hoped to be able to use OpenVPN but it does not appear. Is there any chance to activate it?

In any case, thanks a lot for the support! Even without OpenVPN the many options of dd-wrt makes it a great choice.

You have a tunnels page perhaps you can use WireGuard, which is light weight and much faster and easier to implement than OpenVPN.

There have been a few routers with Kernel 3 and 4 MB flash which got WG backported

WireGuard guides are a sticky (first few threads) in the Advanced Networking forum

Thanks

I had already seen that with eth1, also on screenshots from others.

Yes, that is indeed strange.

(as egc has already mentioned, the 4MB refers to the flash memory and not to the RAM)

I have a V2 and these are best used as a basic wired AP. Any other purpose is pointless.

So we have looked at the hardware specifications again.

The processor has two network interfaces and is also used in real routers.

It seems that eth0 is not connected and not working.
Can you confirm that eth1 is working properly?

unbridge eth0 (change bridge assignment from default to unbridged)

if this works please test eth1 as WAN port again.

Brainslayer says that he can customize this

[maob]

I can confirm that eth1 is working fine and unbridging eth0 does not bring any effect. By activating the WAN port the WAN IP is assigned right away as soon as in the networking tab the wan port is assigned to eth1 (with eth0 the IP remains 0.0.0.0).

Which now matches:

https://svn.dd-wrt.com/browser/src/router/services/sysinit/sysinit.c#L1345

But not:

https://svn.dd-wrt.com/browser/src/router/services/sysinit/sysinit.c#L1325

When I have time, I can investigate my v2, but here's hardware info from OpenWRT:

I have a suspicion that this is part of the crux of the problem with similar CPU hardware supported by DD-WRT. Have several options to investigate this, but my devices are not readily handy at the moment. I do know that the 940Nv3 doesn't like the startup script for the lan ports to work anymore, just have not had time to test without it as it is serving as an AP elsewhere.

@maob: Check next public release unless a test image is posted in this thread.

This thread is about the WA901NDv5 and not about the v1 v2 v3

They have completely different hardware

It starts with the fact that your v2 has Realtek LAN and the v4 and v5 versions have everything integrated in the SoS.

And whether the "switch commands" have any effect depends on whether the router has a working switch at all.

The v5 has a switch integrated into the SoC
However, the switch shows that only one Gbit MAC is connected from the CPU and nothing else.

The switch will be connected to eth0 and will not be wired any further.

eth1 will be connected directly to the external RJ45 socket.

maybe this is different for other versions who knows
