The strange thing is that this network card with another similar device works fine!But with the bridge – no!

Can something advise? Are there any special features for Intel network cards and PS Audio bridge ?
Thank you!

If you are not connecting to a router/switch, you need a crossover cable to connect directly to the bridge.
