B4R Question Faulty Ethernet shield ?

[derez]

Got my W5100 from Aliexpress, mounted it on Arduino UNO.
Coming to this part of the example:

    If eth.InitializeDHCP(MacAddress) = False Then
        Log("Error connecting to network.")
        Return
    Else
        Log("Connected to network. My ip address: ", eth.LocalIp)
    End If

the logging stops, no errors, nothing is printed.
Changed to this init:

eth.Initialize(MacAddress,Array As Byte(192, 168, 0, 116))
Log("IP= " ,eth.LocalIp)

This doesn't stop but I get IP= 0.0.0.0 and no connection later on.
Checked my router -it does not appear there. Checked another router - the same.
changed mac addresses (invented) - nothing.
Checked with an Arduino example (DHCPAddressPrint) - nothing.
Also - leds on the connector do not light or flash.

Comclusion - the board is faulty.
Any possible thing that can be done and I may have overlooked ?

Have you also changed your ethernet câble?

 

[derez]

Yes tried with two and other devices work fine with this cable.

Thanks. After the long discussion there the result is a HW problem in a board.

Hi
I have same problem
How can you fix this problem?

The problem was the cable. The Ethernet shield is more sensitive then other devices, so check first with a good quality cable.

I change my cable but it again say "Error connecting to network."
