Hello, we have to connect two computers via ethernet in an industrial enviroment. we are using a crossover cable to connect both computers.
If i connect my laptop running with bateries to one of this computers the ethernet connection works fine but when i plug my laptop to the power line the ethernet connection brokes. This power line is common to all devices and we have tested with several cables.
This problem does not happen always. Some days all seems to work fine but other days the ethernet connection does not work a all.
Any ideas?
