Duet Maestro won't connect to PC (Ethernet)

[droftarts]

Can you post your config.g? On the PC side, check you have not set a router/DNS/default gateway address in the network properties dialogue box for the Ethernet port.

wont affect communication to the same subnet as the host is on

@droftarts
config.g

also tried setting gateway and dns before, but to no avail

The ethernet port on the PC also works when connected to the ethernet port of a wifi extender.

Can you run the Duet plugged into this?

I can’t check your config.g at the moment, as on my phone with sleeping baby on me! And can’t open a .g file in iOS, or change file type. If you could post the text, or save with a txt ending, I can.

I’m writing the ‘alternative’ network connections wiki guide (Duet WiFi in access point mode, Duet Ethernet direct connection), so would be really good to get this cracked.

Other thoughts: firewall? Windows hosts file?

Edit: the weird thing is no Ethernet lights, like the adaptor in the PC is disabled.

or like the combination of Maestro and Laptop fails to negotiate the link. forcing the right combination of link speed and MDI/MDX on the laptop will likely work

@droftarts
Here you go config.txt

The Wifi extender only has a single ethernet port, so I can't plug both into it.

Not sure what windows setting would block the port entirely for the Maestro, as it works with other devices.

Just fyi, it's not a laptop, but a normal PC. Probably doesn't change anything though

Will see if I can try with a laptop or different PC and report back

Hi,

I would think that when connected to your PC there should be some lights on the Duet regardless of network settings.

Are you positive the crossover cable is actually a crossover cable?

@fcwilt

Right. I'm sure it's a crossover cable.

Tried with the laptop and there we go - it works. Maestro is blinking and accessible via 192.168.4.120. Worked with direct and crossover

Maestro is also blinking when directly connected to the wifi extender. Seems like the issue is with the ethernet port on the PC. Will try to reinstall the driver and reset/check all settings there.

[dcw259]

Reinstalled the newest drivers from intel, but that doesn't change anything.
The PC seems to work with every device I plug into it, except for the Maestro

On the laptop (win7) it worked no matter if I had set a static IP or not by the way

Wasn't sure what you meant with link speed at first, as english isn't my first language. Now I got it, but I'm sure I didn't need a jfgi-link for this.

However it seems the Maestro can only do 100MBit and windows somehow thought it has to force it to do gigabit instead.

Windows should be able to negotiate the correct speed.

If you normally use WiFi to connect from your PC to your Router perhaps the Ethernet port on the PC is disabled.

Its not windows, but the network card/and or drivers that fails auto negotiation - have seem similar issue under Linux as well.

99.999%(?) of device combinations work with auto negotiation, some weird combinations won't but will usually bring up the link if the speed or duplex settings are changed. Some network cards also allows auto mdi/mdx settings to be forced to get around crossover issues. Not sure I've seen it happen with Intel NIC before though. Sometimes better/shorter cables can help, but software settings are usually the easiest.

@dcw259 It's working now? Thanks @bearer for the resolution if so, though as a native English speaker, I didn't get what you were talking about "link speed and MDI/MDX" either! He did ask you earlier how to change this.

I'll add some info to the guide about link speeds and auto negotiation as a troubleshooting step.

I'm not a native English speaker either, however its pretty common networking terminology - and this much effort was required to find out what I was talking about:

(then again it was 99% just some software config issue. so why bother right? which makes me run out of patience..)

I know, I was a network admin for years. I just try to keep things simple.

Yea, everything seems fine now. Really weird that it was just this combination of Maestro and PC that didn't want to set everything automatically.

@fcwilt said in Duet Maestro won't connect to PC (Ethernet):

It was never disabled, as it worked well with other devices plugged into it.

But either way, thanks for the help everyone
