Network Connection Problem
« on: July 31, 2013, 08:15:53 pm »
I am trying to setup a PC as a server for video over my home LAN to laptops, and other devices.

Currently, I have a problem with one client that connects using WiFi G at a steady 54Mbps.

I select a TS file on a network share, which is MPEG2 of roughly 14Mbps bitrate.

So, 54 should be plenty, right ?

But I get constant pauses.

I tried playing the file through VLC, and saw an interesting thing - the graphic indication at the bottom indicates that every few seconds, the player needs to stop and fill up a buffer.

So, I ran it with Task Manager running on the Networking display, and it would never get above 20% bandwidth being used - and the display also indicated a steady 54Mbps.

I have run the same video on a similar laptop (same CPU) connected to a Gigabit Ethernet connection, and it plays smoothly.

Any ideas ?

Yup - Get some blue string in.  If you want to see the "real" throughput copy a file from one PC to the other.  It will be a lot less than the supposed link speed.  I find even using "N" that it is not reliable so I wish you luck using "G".

Running electric string is not an option for me. Multi-unit dwelling (i.e. apartment for the US types) means that knocking holes in the walls is not something I can easily make happen. The floor is a possibility but would involve messing about.

I've gone down the path of ethernet-over-power and I'm working with 500Mbps (nominal) adapters. One to bear in mind.

I've used powering adapters and got pretty good results.  They are like reliable wireless.  The other option is to try the newer WiFi STDs as you will get better bandwidth

Thanks for the replies.   A web search indicates that Wifi G has so much overhead that the so-called 54Mbps is actually more like 24Mbps in a best case scenario.   The fact that I am only getting 12Mbps despite the connection being "54Mbps" and "Excellent" connection, indicates that it is not the best case scenario. :)

I have a USB Wifi N standard adapter, so I am going to try that...
