802.11n not fast enough to stream things that it should be able to stream

Hi all,

I've got a time capsule with a computer connected to it by ethernet. I have a laptop that I would like to stream videos to over 802.11n. I know I can stream 1080p stuff, but I've got some videos that are 700MB/hour with is ~1500kb/sec. This is well under the 802.11n threshold, but it stutters every 4-5 seconds in playback.

What's wrong?
 
If you have any "G" devices on your network, it'll slow your router down to G speeds, and you won't get N speeds on any of your devices.

Maybe that's the problem.
 
How far is the Time Capsule from the laptop when you're trying to stream?

Also is your laptop fast enough to play said 1080p video?

My iPhones wifi is turned off... is there any way to force the router to only do wireless-n?

Yes, it's a MBP. It's about 10 feet away.
 
The way how 802.11 works is that every time a client connect the speed is halved, so as soon as you connect one client you are down to 150mbps (based on a total of 300mbps with 0 clients) from there it just goes down accordingly. How many devices you got on the wifi? Too many and it will crawl to a halt. something else, make sure the router isn't near any other electrical stuff.

The iMac is connected by ethernet, so only the MBP is connected wirelessly.
 
Are the videos contained on TC? Or the iMac?

Also don't forget about standard background noise, or interference which will cause slow speeds.

If there are a lot of wireless networks around you, on top of that with cordless phones, microwaves etc then it will slow down your wireless network

Don't forget as well that the speed it says that the n standard is capable of is a theortical maximum, and unlikely to be seen in the real world

On a drobo connected to the iMac. If I copy the files to the MBP, it transfers faster than required to stream (only 5-10 minutes max).
