Oh these complex networks we created

My basement network went down today. I have an A6 from Fiber modem feed my melco via fiber. It also feed my office switch via a wired connection. The two channel setup is on melco. The melco fiber out feeds the Home theater rack via a 30’ fiber. it all was down.

it ended up being an sfp went bad. What a pain to find and then my office PC stole the Roon IP for some reason. I had to shut it down and pull the dock off network and power. put it back and and thankfully DHCP took over and left the roon alone.

it was so weird, if I put the office wire into Melco it was fine, as soon as I moved back to A6 (where I wanted it, before the fiber to 2 ch) roon would loose internet. PC would always win. put it back in melco and roon came back. Thank god i had a spare optospan. The one that went bad was a Finsar

Fun times. … did not even get a chace to sit down and listen…sad

Brian, you don’t have static IPs assigned?

No. Inlet DHCP do what it needs. Seems that when my pc was off network and I rebooted my NUC it stole the IP PC had. Then when I restored the office network cable it stole it back. At least that’s what I think. I rebooted pc and reset dock which seemed to do the trick.

Most routers allow you to reserve fixed IP addresses for various gear. It’s not something us old people can deal with but maybe a 14 year old could do it for you. On my router this works even though I use DHCP.

my Innuos Zenith mkIII would acquire a new IPAdress from time to time from DHCP; drove me nuts. I have a mesh network, I created a reserved address on my Orbi router for the Zenith; problem solved. I’m 67, retired engineer and have been in high tech my entire life. Started noodling with electricity since the 60s. Ever plug a capacitor into an AC outlet directly? :winking_face_with_tongue:

Yeah it’s just not something I want to do. Lol. First time it’s bit me ever. The hardest part was finding the broken sfp

This is not an issue with physical media. Lol
