Wired Network Problems

[rimmi2002]

Hi I just setup a new network. Here is the order:

Motoroal SB6121 --> NetgearR6100 --> TRENDnet TEG-S81g --> To 7 wired connections from home internal wiring through the main home cable box.

I have my main computer and HTCP both on a wired line through the TRENDnet TEG-S81g. I just set this up last week. The internet works great. Whenever, I tried to transfer large files or large amount of data, the wired network breaks down. I tried a transfer of ~16gb and it broke down half way. This has happened serveral time for transfers of various sizes. (Main computer lost all ethernet connection). It had to be restarted with wire replugged to get ethernet going again. I have transferred a few video files in size from 4-10gb of the network, thought they have transferred fine on the surface (full file transferred) when I try to play the video file breaks down in the middle of playing...I have to forward of skip past broken data points...loosing a few mins of video.

My networking wire in internally wired in the house with Cat5 cable. I am using Cat6 cables to connect from the Cat5 jack to the computer. Do I need to be all Cat5? I dont think this should make a difference, but right now I am trying to figure out what I can do to fix this.


Not only this but when I am transferring large amount of data, the speed is @~68MB/sec on the network, but if I try to surf the net at the same time its very slow. All other things on the network slow down. Any advice on how I can trouble shoot this?

Is it the switch that can't handle the load or is it the router? Any advice will be great. Thanks.

You could have a bad switch or even a bad cable causing the problem. I've had bad cables interrupt data transfers and I about pulled my hair out trying to trouble shoot the problem. Do you have QOS enabled on the router? If yes, have you taken a look at each connected device to see what traffic load it is putting on the router?

Cabling is backwards compatible so don't worry about having the different standards in the network. If you had a cat 7 feed and were attempting to maintain a 10gbps throughput then it would matter. If your cabling checks out I would begin a process of elimination until you locate the culprit.

Can you please guide me or show me a link that explains how to test cables. I just bought the house and suspected the internally wired cables were bad intially also. Thanks.

Is the problem pc in a particular room on a particular jack? If you connect another pc to the same jack does it exhibit the same behavior? If you move the problem pc to another jack does it still behave the same way?

Disconnect everything.

Start with one computer that is connected directly to the Router.

Check and if OK add another computer, and so on, and so on, until you find when/where the problem starts.

Good suggestions so far. I do think you would want to test both the wiring already there and a straight connection to the router. Hopefully the wiring in the house is in good shape.
