TJF1960 Posted January 6, 2012 Posted January 6, 2012 I am having an intermittent network problem. I relocated the ISY and plm to the garage. Ran new cat5e. No troubles for a couple of hours then the ISY would report -100 loss of network. According to the error log it would loose network then reconnect sometimes rapidly. I thought maybe I had a bad port on the switch. Changed ports a couple of times, no help. Then I plugged the ISY directly into the router, no help. I ran another cat5, no help. I noticed that when the red light does flash on the ISY the 2 green lights on the rear for the network cable are still lit and the one is flashing occasionally while the red light flashes. I bought a network cable tester and both new cables tested good. It also seems that way more errors are produced when it is cold. I brought the unit back into the house and ran it for over an hour with no errors. Put it back in the garage and it ran for 30 minutes then produced the network error.The ISY has lived in the house for the last couple of years and that room stays between 75 and 80 degrees year round. At this point I don't know if it is the length of the cat5 (<80ft) or what. I was carefull not to route the cable near any power wires. I am normally a very good troubleshooter but I am stumped at this point. I am looking for suggestions. Thanks, Tim
Michel Kohanim Posted January 6, 2012 Posted January 6, 2012 Hi Tim, I do think the length has something to do with it. If you have another switch/router, you might want to put the switch/router in the garage and the hookup ISY to it. I suspect you are getting a lot of collisions because of the length. With kind regards, Michel
