Hi !

I can get an IP with an USB rj45 adapter, but route is empty :

The latest update changes nothing.
Getting the network through /etc/rc.d/rc.inet1 works.

The latest update didn't fix any bugs, it only made it work on armv5.

NetworkManager works fine here after killing dhcpcd, ifconfig eth0 0
Are you sure that you don't have DHCP configured in rc.inet1.conf ?

If you do you should set it to ""

Was set to yes, but removing it changes nothing.
I just noticed that I have a :
Aug 22 21:16:15 darkstar NetworkManager[1244]: <warn> [1471900575.3462] device (eth0): failed to find device 3 'eth0' with udev

As I tweaked udev the problem can be there, I'll check that.
Thanks for your answer.

Crap, I have the same problem without touching udev :/ .

When I set NM to use dhclient, I get the routes but not the DNS, weird.
The internal dhcp client doesn't work.

For an unknown reason, using dhclient now works. Not dhcpcd still... Only the update batch changed.

You can try changing the settings for dhcpcd. I don't find it particularly reliable either but I think it's more of a local issue with a dodgy switch I have:-

Within /etc/rc.d/rc.inet1 make sure that zeroconf is disabled:
If you don't see the "-L" in yours, add it in.

Then try changing the time out from 15 seconds to permanently waiting ("0"):

If it is an dhcpcd vs. dhclient problem you could also try to uncomment the line with clientid from /etc/dhcpcd.conf and comment the one with duid. Otherwise it won't work with my router.

I will try that, but the problem I have is agnostic to DHCP clients. Even PXE booting and the DHCP client within U-Boot times out on the first try, but succeeds immediately on the 2nd. It only started happening when I had to replace a switch due to a fan failure.

Did the change with /etc/dhcpcd.conf , did nothing.

And the changes I suggested?

I did them at the time you told me but nothing changed.
As of dhclient, it "magically" got the DNS yesterday.
I tested with a minimal set of tweaks (like key mapping).
I closed the issue because I now have a workaround, but I'll keep an eye on this. I can test on another ARM devices.
