Poor streaming connection/speed
ReadyNAS NV+ v2 WNDR4500 2 x Powerline AV500 Tvix N1 Network Player Hello. My first post at the ReadyNAS forum (previous Stora owner!). I hope someone can help me; I'm getting really frustra...
Oops - I meant 802.3x...
802.3x is not a wireless protocol, so the specs you quote are not relevant. Netgear does a more complete job on listing the technical specs for their switches than they do for their routers, so it's hard to know if the WNDR4500 supports it or not.
The NAS is connected via gigabit, and the player is only fast ethernet. If the player tries to read too much data, the router needs to buffer it, because the link to the player can't keep up. If the buffering isn't enough, then the router loses data, and the throughput plummets. 802.3x allows the router to tell the NAS to pause its sending, which prevents the problem. The player TCP stack shouldn't allow the player to create this buffer overrun problem, but many do (including the older Netgear media players).
One easy way to diagnose this is to (temporarily) manually configure the NAS to run at 100 mbits. If the performance issues go away, then you need to insert a gigabit switch behind the router which supports 802.3x. They are not expensive.
Also, if you have jumbo frames turned on in the NAS you should turn them off. That can also cause performance issues with fast ethernet devices (which don't support jumbo frames).
