1123 network stability issues
Hi everyone, first post here so pardon any errors in etiquette please
I've owned 3 1123-k units since 2014 and they have always exhibited instability, most notably with IP network connection. Aside from the Pandora issue, I had one that had a loose rj45 connector that had to have the board replaced, but all three have had a problem where after the units are in use (as in plugged in, on or standby) for some time the network connectivity drops. All are hard wired with Cat5e cable to rj45 connector and initially network set up goes fine, unit is seen on network, can connect to internet, iControl app sees it and works fine. After a while, from hours to months, the unit drops off the network. Cannot ping, router doesn't see Mac addr, yet in System Setup, the unit still shows all network settings intact. Only measure I have taken that seems to work temporarily is power off or hard reset. Longer I leave without power, completely unplugged, better it seems to do. Something else of note, during an earlier period of desperation, I replaced one of the 1123's with a vsx-80. The vsx-80 has been ROCK SOLID, never an issue in almost 2 years. The units are in two separate homes, yes I've tried rotating them between homes/networks and one AV shop analyzed one unit with the behavior and declared it in good shape.
Was hoping latest (finally!) firmware might address, while good for Pandora, in my case it didn't help stability.
Anyone else seen this issue? I did try to scan board but did not see any postings on this. Thanks for reading and appreciate any suggestions.
