Most TV recordings play via my DMA2200 extender without any problems. Large files, such as movies, though, start to show blocky images after about 20 minutes which quickly gets worse until the picture is completely broken up. There is often some corruption of the sound too. Stopping and resuming playback fixes it for about another 20 minutes.

I’m using a wireless 11n connection to the DMA2200 at the moment, but it does exactly the same with a wired connection. The PC is wired to the router.

Any suggestions, please?

Hi Nick,

can you elaborate on Wireless 11N?

is your WLan Speed 11mbps or 300mpbs?

i gave up on wireless N (300mbps) because it simply didnt do what it was supposed to do. What Router are you using? when u tried ethernet connection, did u have a lot of traffic on ur lan at the same time?

Im using a mixture of Gigabit Lan as main which VMC and ReadyNAS are connected to. Im also using 200mb powerline adapters for the extender and i dont see any of that behavior when playing back divx/xvid thru the DMA2200 from either the VMC or ReadyNAS.

Other question is what format are you playing back and getting the issue with? is it DVR-MS? if yes.. i dont see that issue either.

For me dualband N was farcical and was a failed £500 investment that i have now put behind me. My current setup does exactly what i was hoping to achieve with bulletproof reliability.. i can now go to bed safe in the knowledge i dont have to get up to start muckin about before i can watch something.

Thanks for your reply.

I'm using 802.11n (draft) and getting about 120Mbits/sec, but I get exactly the same problem with a wired connection.

It's a D-Link DIR-655 Gigabit router, but I've tried a Belkin F5D7633 too and, again, the problem is the same.

The format is DVR-MS.

It only happens with long recordings, but not necessarily when they are a long way through playback.

Hi Nick,

sorry for late reply been out of country.

when u say 120mbps, is that actual throughput? or just what the systray util of ur wifi card is telling u?

my vmc based card used to say anything from 162mbps - 270mbps but the reality was something entirely different. I was using a Netgear card, their systray util is actually quite handy cos it shows u your bandwidth utilization and you can actually see packets been transmitted and received. I found the 162 and 270 was a complete myth, i was getting sometimes as low as 5-10% bandwidth peaks with dips down to zero. This made N useless for streaming from the NAS to the VMC box, let alone streaming to the extender only half a meter away through a thin wall.

Does it do this when u stream anything else? such as live TV or DivX/Xvid, WMV or Mpg etc?

Also do you have the network warning enabled?

Thanks for sticking with this. I don't think we can get too hung up about the wireless throughput, because the problem is identical with a wired connection. The 120mbps, though, is what the router admin console says I'm getting.

I get a different problem when I stream DivX/Xvid. That just stops after about 30 minutes as though it has come to the end of the file, and goes back to the menu. I have to restart and fast forward to where it was previously.

Live TV is perfect. I can watch it for hours without a glitch.

I do have the network warning enabled, and sometimes before it misbehaves it shows an error, sometimes not.
