In one installation we have a RUTX08 which does not get an IP address (DHCP) from the provider's router (Swisscom, Internet Box 3). My laptop obtains an IP address without any problems. In the house next door we have the same installation, everything works there. We have already exchanged the various components with each other. It remains unchanged. I have also already connected another RUTX08. Same problem. If I install this RUTX08 elsewhere, everything is okay. From the provider's side, everything seems to be in order. The RUTX08 run in standard mode. Any idea?
