Hi,

My home network is set up as shown.

Computer1 --ethernet-- Modem/Router --wireless-- Computer2

Modem/Routher is Netcomm NB6+4W and it's connected to the internet
Computer 1 and 2 both run Windows 7.
Computer 1 has various folders containing video that are shared in my home network.

====Symptoms====

When Computer 2 plays these files, the video will often "freeze" for about ~30 seconds before it "unfreezes", causing the video to play in fast forward until it regains the 30 seconds it just lost. I've tried using a few media players (Media Player Classic, VLC, Windows Media Player) but the same thing happens.

This problem is rather intermittent. Sometimes it happens quite a few times/video and sometimes I'm lucky and I don't get it for a couple of videos. It does seem freeze more frequently on higher quality videos (eg.720p).

I thought that the wireless adaptor on Computer 2 might have been the cause but even after I connected Computer2 to the Router directly via an ethernet cable, the problem persisted.

Strangely, when I play the same video files on my old laptop which is connected to the router wirelessly, I experience none of these problems (regardless of whether I boot the laptop in XP or Win7 mode).

When the video freezes, I lose access to all the other files shared by Computer 1. I then have wait until Computer 2's green address bar fully loads.

Looking at this, it seems like Computer 2 is losing connection with Computer 1 every now and then. Internet access isn't affected during this interval though.

I've had this problem for over a year now and during the time, Computer 2 was reformatted but even after a fresh reformat the problem was still there.

I'm getting sick of this problem but I'm at a loss as to how to troubleshoot this problem so any advice is greatly appreciated.

Hi quantic,

I'm afraid not. I shared the folders by right clicking it -> "Share with" -> "Everyone". I haven't had any problems with my laptop when running Win7 (when it boots in XP, Computer 1 is sometimes completely invisible or the folders are "unaccessible" but that's probably a problem with connecting XP to Win7) so I assumed that sharing in this fashion was okay.

I'll play around with the Homegroup when I get the time though.

If you hold down the windows key and r and type in
services.msc
and press enter, this brings up the services. Is Link-Layer Mapping service turned on or off on each computer (A, B, and laptop [C])

I just tested the laptop (booting with Win7) with the video files and to my surprise, they froze. I apologise for misleading anyone. Guess I should have checked myself rather than trust my brother's words blindly :P

I'm not sure if it's turned on or off. When I check the properties, it says: "Startup type: Manual" and "Service status: Stopped" on all 3 computers/laptops.

Here's a screenshot of Computer 1: http://img10.imageshack.us/img10/718/linklayermapper.png

Before I turned the Link-Layer Mapping service turned on, I changed my main computer's LAN network adaptor's Speed and Duplex from Auto Negotiation to 100Mbps Full Duplex. After that I didn't experience any freezing for a day. But after I restarted the main computer, there was a freeze for ~10 seconds while streaming. So I guess it may have been a coincidence though I never had a whole day without freezing before.

In any case, I changed the Speed and Duplex back to auto negotiation and turned the on the Link-Layer Mapping service on all my computers. It's been 2-3 days now and everything has been going smoothly. Hopefully this has really solved the problem. If so, I can't thank you enough thrillhouse :)

You are most welcome! Glad it's fixed.
