How to set Network speed


#1

I been looking around and don’t find anyway to set the network speed or duplex. Is there such a thing?


#2

As far as I know the device tries to connect to the highest speed (=100 mb/s) available. If auto negotiate fails it drops back to 10mb/s. It cannot be configured or set from software.


#3

@ Patrick - In my case I need to control the speed and duplex.


#4

I think the only way to control the speed and duplex is from a managed switch. If you set a port from that switch to 10 or 100 mb/s full or half duplex then your device will use it.


#5

@ Patrick - Yea, I though of that. I need to get a hold of the network class/driver and work on it. There needs to be a property to control that.


#6

If you find that, please let me know, i’ve got a couple of spiders out in the field with a negotiate problem.

btw: the network driver is lwip and is part of netmf


#7

Thanks for the info. I’ll let you know. Right now I’m fighting a power up ( hydra ) issue where the network doesn’t initialize on power up. But after power applied if you hit the reset then it is fine.


#8

Was there anything learned about changing the duplex mode for a spider? Same boat as you. Gotta force full-duplex on the spider. Can’t change switching hardware.

Thanks -AP
