Wep Page Disconnections

chas2706

Hi folks,

I originally purchased a chinese clone duet wifi almost a year ago and had nothing but constant wifi disconnections. I looked on the forum for answers and tried everything but got nowhere. I blamed it on the clone board. The disconnections were so bad I often had to stop myself throwing a cup of coffee over the Duet board.
So, last week I threw the boat out and purchased a genuine Duet Ethernet direct from Duet3D.

Surprisingly, I still get lost connections on ethernet.
Here is a small copy and paste from the gcode console during a print today;

Please post the results of a M122

Also do you know if your Wireless system you are trying to connect to is 2.4 or 5 ghz?
If it is running 5ghz I think you will struggle to connect.

I am connected via ethernet on my new Duet board.
I'm still printing at the mo but ive had no further disconnections since 14.09.

Are you quite certain that nothing else uses that IP address? Your router might be assigning it to something else via DHCP. I suggest you check your router settings, to make sure that the pool of available DHCP addresses doesn't include 192.168.1.6. If it does, then move the Duet's IP address to be outside that range.

chas2706

That sounds feasable. Nice one, I will check and change if necessary.

PaulHew

@chas2706 My Bad, I read tooo fast! Did not realise you have an ethernet now.

chas2706

@PaulHew

No problem, thanks for your input anyway.
Im going with @dc42 's suggestion but can't look into it yet. Work is in the way!

I think it's good practice to set a static IP for the Duet on the router itself.

Changed my static ip to 192.168.1.106 (definately not used by anything else) and here's what i get today:

do you have an ethernet crossover cable?

if so connect a laptop directly to the duet to rule out problems with the infrastructure.
both need to be set up for static ip for it to work.

A Former User

is the crossover cable required? i'm of the understanding the Duets does not support Auto MDI/MDX, but I thought it was enough for one of the two sides to support this, effectively rendering crossover cables a moot point since early 2000.

chas2706

Sorry, I don't have a crossover cable and no such cable is mentioned in the Duet "get connected" pages.

Veti

if you computer supports auto mdi/mdx it will work with a normal ethernet cable
