Weird issue with Yamaha RX-V771 AV receiver
So today when I was setting up my Steam Link, I noticed that my Yamaha receiver despite otherwise functioning properly has dropped from the (wired) network. Tried plugging and unplugging the cable, tried different cables and ensured the cables do in fact work, but nope, the receiver claims "no link" despite other devices working just fine off the same cable and router port. During the receiver restarts, I noticed a notification regarding a firmware update (currently on 1.21, system offers 1.80) and since I figured it had already downloaded it I thought why not give that a go.
The receiver goes into standby mode, the front panel display says "NETWORK UPDATE" and then just sits there. Yamaha website says the update might take up to 15 minutes and I let it go for 40+ twice without anything seemingly happening. The receiver starts normally (and unupdated), which is where I decide to go the manual USB router, only to encounter the exact same problem. Using the buttons suggested by the manual I get it into USB UPDATE mode and it just sits there, for 40+ minutes doing nothing which is where I give up.
Just the LAN connector somehow dying I can understand (even if LAN adapters in my experience generally die last), but how come the system refuses to update itself, regardless of method employed, while otherwise continuing to function in a perfectly orderly fashion? Is my unit just dying in a somewhat unusual fashion or what's going on here?
