I appreciate all the responses to my post. I have upgrade the router to the latest firmware and am able to access the setup menu after my pc got a 192.168.0.10 address from router10 and I am able to access the setup menu from 192.168.0.1
I have not do a cutover to the router10 having fail the first time and going to wait until weekends to do so.
Have anyone use a copper DAC cable inserted into the spf+ port ? I observe that it don’t seem to work as there is no link activity light. When I use a spf+ optical module , the link activity light is working. I am trying to replace my pfsense firewall which one of the spf+ interface is not working with the router 10. I have isp 10gb broadband and my home network is a combination of 2.5gb and 10gb( including wireless AP)
