Nettwork configuration

Hi, I’ve accidently set network configuration on my My Cloud EX4 to 1000m/s but my network speed is only 100m/s and now i cant acces it. Any ideas how to fix it?

don’t you have any laptop/pc with a 1000m/s network card?

If YES then connect the NAS directly to it, set the host network to comunicate with the NAS and re-configure it.
Elsewhere you have to reset it
