August 21, 2025Aug 21 Hi Guys, Here's my problem:I have a Dell R710ii server that I set up Unraid on about 5 years ago, at the time I was with a different ISP and used an Asus router.Due to work, moving house and family commitments this has been powered off for several months, during which time I have changed to a different ISP and now use their router.My issue is that the router does not seem to see the server, the cable is fine and I can connect my laptop and use the network etc. but when I connect into the Dell NIC I get lights flashing but no connection to the router!The router default DHCP range is set from 192.168.1.64 to 192.168.1.253 with the router on 192.168.1.254 the lower IP's are for fixed IP's.My server has a fixed IP of 192.168.1.186 gateway of 192.168.1.254 subnet of 255.255.255.0 and would not connect to the router, I thought it was due to the DHCP range, so I altered the DHCP range minimum from .64 to .200, still no connection with the router!! So I reset to factory on the router and altered the server to .40 and still no joy!Can anyone advise further actions? I'm not totally familiar with networks etc but did get it all working originally at my last property!Thanks for any help/pointers,Mel.
August 21, 2025Aug 21 Author thanks for the reply, yes I did, also the 2nd NIC port is set to DHCP as a test that I did before I tried all the other changes.mel Edited August 21, 2025Aug 21 by Silhouette UK
August 21, 2025Aug 21 Community Expert I assume it's not getting an IP when in DHCP? If yes, and the NIC is correctly connected to the router, and it works with a peer to peer connection, it suggests to me a compatibility issue between the NIC and the new router.
