NetFlix streaming problems
Here's my issue.......when streaming, video and sound freeze completely for about 30-60 seconds. Or video keeps streaming and sound freezes for 30-60 sec.
There are a lot of possible reasons for these kinds of problems.
I have recently looked at the same problem for an AppleTV (nice) iPAD (joy) and iPOD trouch (passion). Most of the study was on the AppleTV (quality dedicated streaming device). I'm leaving out the technical details, but you can infer from the comments that they are obvious.
1) The WI-FI can "retrain" due to interference from other units. The network may look OK, but a sniffer or spectrum analyzer will tell a different story. A hard wire to the network can address this issue.
2) Local network congestion. Running a big download can congest the local network feed. This can be potentially corrected by enabling Quality of Service (QoS) on the local router (good luck). Of course you could trim your torrents down to a single stream...
3) ISP network congestion. This is a problem in some areas. It's hard to prove and pretty much out of your control. If you get an IT person to confirm that it is a problem, the ISP can enable QoS in their equipment and / or get more WAN bandwidth.
4) WAN network congestion. This is a crapshoot... hard to prove and harder to fix. Evan a large ISP has limited ability to fix these kinds of problems. The best chance is to look for an ISP that is well connected.
5) Local equipment problems. The Apple TV has subtle firmware problems. I have seen it get confused and need an occasional reboot. It seems that they leak memory in the network layer or perhaps have basic hardware issues (flaky memory). Make sure that the unit is not hot (like smothered with stiff and on top of the toasty cable box) and has adequate cooling air. If your network has issues (like lots of bad wireless packets), look to improve the network quality (e.g. hard wire and QoS).
6) NetFlix streaming engine is overloaded. I doubted this as the engineers should design out this possibility. However, watching popular movies have problems and obscure titles don't. So, there is an argument that the servers might be overloaded with retransmissions - due to network errors. If there are enough the server can be overloaded...
So, do what you can to clean up your network (if you are savy run check the network for lots of retransmissions), make sure that your equipment is happy (e.g. cool) and avoid watching popular movies during prime time (there are lots of marvelous obscure titles).
I hope that this helps.
