Hello,
i've got a problem with my D7800: since now i used it as AP only.
But now i configured it as router with wan.
OOB the eth0 interface is a vlan 2 with cpu port 0 tagged plus port 5 (wan-port).
But it doesn't get any traffic if i connect it to my modem with 100mbit link.
If i connect a 1Gbit switch between modem an wan-port it works.
I am on snapshot release.
Can anyone confirm this?
Thanks
Does it work if you use a cross cable to connect the two devices?
If it is not a cable issue and it works with a switch in between them, my guess is that the ports are not auto sensing for tx and rx.
Well, the port is syncing with 100mbit.
I dont have a cross cable and i dont think it is a cable issue, because i use the same cable if i configure the port as second vlan on eth1. There it works.
I don't exactly follow you.
Are you suggesting that the speed of the wan port is locked to 1Gbps and if you connect it on the modem that supports 100Mbps it won't work, but with a switch between them it works?
With a gigabit switch. Yes.
In other words the WAN port doesn't seem to correctly auto sense the port speed?
The Port is connected with 100Mbit as ethtool is showing. But it won't receive any traffic.
The WAN Port is normally in a vlan with the interface eth0. If connected to gigabit it works normally.
Now i configured it as a vlan with interface eth1 (where also the other "LAN"-Ports are configured). It is auto sense 100Mbit correct. But now it is also receiving traffic.
Could you paste here the output of ethtool eth0 ? Preferably when connected to the modem.

Looks like it is only receiving traffic and not sending anything. Can you verify that with tcpdump?
Have you tried manually locking to 100Full? Should be with ethtool -s eth0 autoneg off speed 100 duplex full. If there is no luck, try also the mdix yes option.
Tried everything. 100 Full/half 10 1000 autoneg off on etc .... nothing works.
I think the issue is in the dts file.
Comparing with the dts from the Netgear R7800 (which is almost the same HW without VDSL modem) there are some differences for the gmac devices.
But who knows if it is only my router or a bug in config/dts/driver/whatever ...
I can confirm mine works with a switch too, I couldn't find any configuration to make it work without it.
Maybe someone who has the device or sees something obvious can make us of this....

Old topic I know, but this can actually work without a switch. I found a topic from vvolcano TL-WR1043NDv2 WAN connection and reboots that had a clue. Swapping the Wan and Lan eth ports did the trick. In LuCI, in interfaces edit LAN and in physical settings change it to eth0.2 (remember to un-tick eth1.1), and in WAN change the interface to eth1.1. If you've added an interface for a bridged modem, also change that to eth1.1 so you can still access it. Now put the WAN cable into port LAN 1, and put the LAN cable into the red WAN port. Now you can access the internet without needing a switch. I don't think the other ports will work, I only need the one.
@ebswift this works!
However now the 'LAN' port doesn't work anymore for me after swapping them, Wifi works though so it's still usable, just wondering if there is anything else you did to get the LAN port working?
