New HAP ac2 - wifi works, cable doesn't

Hello,

I got HAP ac2 for home network. The router transmits wifi with working internet to phones, tv, but if I try wired connection to PC I get no internet and “ehthernet doesn’t have a valid IP configuration” error if I try troubleshoot network problems. All setting are default other than setting wifi name, pasword and region. Any idea how can I fix it? Thanks

By posting your config to see where it all went wrong…

This is indeed a very standaard configuration. Pure default. And that works normally very well.

Where does the “ethernet doesn’t have a valid IP configuration” appear. Probably in the PC itself.
Check the ethernet setting of the PC. It should be on “Automatic (DHCP)” or “Automatic IP address” and “Automatic DNS” on the interface.
The PC should get an IP address like 192.168.88.253/24. The PC should be able to PING 192.168.88.1.
If you get an auto IP address 169.254.x.x , try another cable.

Shouldn’t the address be on the bridge not on ether2?

Shush, this is @anav’s part to say :wink:

That’s how you know it’s a default config

This is what I recommend, in answer to MKX …
/interface bridge
add admin-mac=48:8F:5A:BB:E1:B8 auto-mac=no comment=defconf name=ether2 bwahahahahah

But seriously
yes…
how dare anyone answer before I… subtract 20 points from all your houses.

Aerosmith got it right.
/ip address
add address=192.168.88.1/24 comment=defconf interface=ether2 network=192.168.88.0

The only other thing is I would not activate UPNP unless you can justify its need.

The only other thing is I would not activate …

??? And what with this ???

/interface detect-internet
set detect-interface-list=all


I hope we are not confusing the OP with all this quip.

I have no idea of the purpose of that part of the config.
I know when my IP changes on my bell fibre connection I have to manually assign the new gateway to the routing otherwise no dice, unlike my cable connection which automagically routes to the new gateway. Perhaps that feature is designed for those instances??

I stand to be corrected of course, but I don’t think it would help in that case. As far as I’ve learned, Detect Internet needs to be able to reach something on the Internet and then dynamically changes the Interface List membership of the egress interface. If you’ve lost the gateway I can’t see how it could work at all. Drifting off the topic, how do you get your configuration from Bell, is it DHCP, PPPoE or what? That should upgrade the gateway and default route I would have thought.

My new router assigned the address to the bridge as default. Maybe it’s version dependent, maybe depends on the shipping version of RoS.
