1. Hardwired. Brand new CAT6 wiring to patch panel in house. Unable to stream audio from any source (Airplay, Pandora, etc...) for any length of time. If I do a speed test from a computer, a previous download speed of nearly 100Mbps is reduced to under 3Mbps. Hardwired virtually unusable.
2. Wireless. Able to connect without issue wirelessly. I can stream without a problem from any source with no breaks in sound. However, it also kills network performance by dropping my 100+ Mbps connection down to under 15-20 Mbps with lag (i.e. I cannot use Skype without audio issues if unit is streaming). Even after powered down, same issue with network. If I disconnect the wireless (by switching network to Hardwired but not actually plugging the receiver in) my network performance shoots back up again.
1. Tested CAT6 with a cable tester - no issues with cable.
2. Changed all other network devices to static IP including Receiver and ensured no issue with IP overlap. Exact same problems.
3. Removed other devices from network (with exception of Macbook for testing) - same issues with hardwired and wireless.
4. Removed network switch and plugged unit directly into router on open port. Same issues persist.
5. Manually updated firmware per instructions. Same issues persist.
I have not gone so far as to install a packet sniffer on my network to find out what kind of traffic the Yamaha is producing that is killing performance. If I simply plug it in, the unit is fine. It doesn't become an issue until I stream music from any source for the first time.
Yamaha was not much help, though they did offer to replace the unit (my next step) and pay for return shipping of the one I have since it is only 2 months old. I will most likely go that route to rule out a problem on the network interface, but I'm a bit baffled since I have network problems when the unit is running on EITHER interface. Perhaps other have problems as well, but I really notice any change in Internet performance as I work from home and am on Skype quite a bit, so when audio quality drops to the point I can't have a conversation, and all I need to do is unplug the Yamaha, I've ruled out the culprit.
However I'm certainly open to any other suggestions!
