I've heard managed switches can be noisy. It is also frustrating that 1 * 16-port gigabit switch costs considerably more than 2 * 8-port switches, but you do end up with 2 more usable ports.

Hi Nick finally got into the interface (PC with 1 Network Cable) and changed the ip address of the switch. After setting it all and everything it sure is a noisy sucker so have ordered a TP link Un Managed 16 port switch. Ill move it on

Thank for your reply

192.168.1.0/24 and 192.168.0.0/24 are both best avoided if you can! It is best to see if you can change the managed switch to another subnet as well.

Anyway, the answer is to change ClearOS interface to whatever. The DHCP server should follow. If you're using a Windows PC, rebooting it should sort it. This is a bit drastic. You could alternatively open a command prompt (windows+r then cmd.exe or Start then type cmd) then in the command prompt type:

ipconfig /release

ipconfig /renew

If this does not work, go to the Control Panel > Network and Sharing Centre, then for your Network select Local Area Connection > Properties > Internet Protocol Version 4 (double click or properties) and temporarily select "Use the following IP address", IP address something like 192.168.0.10, subnet mask = 255.255.255.0, Default Gateway is whatever you set your ClearOS LAN NIC to. Once it is working set it back to Automatic. You may also need to set the DNS server to the ClearOS LAN IP address.
