Wireless network
« on: 05 November 2011, 07:11:49 »
Why does my internal wireless network run sooo slow?

For example, i can download a 300Mb file from the net and it takes 3 or 4 mins
But then copy the same file from pc to pc and it can take 15mins  :(

Both pc's connected wireless to the router......maybe its a rubbish router  :-\

Few reasons to cause it, though that does sound excessive.

A Wifi works like a 54Mb network hub - half duplex, and no segmentation
Presumably Windoze, thus that effecient download will need each packet wrapped up in a nice big SMB wrapper when copying

Ahh.... thankyou for the explanation  :y

Yes both pc's have XP on them......i was expecting it to be the other way round......ie faster internally than the net.

Or somebody else also use your network and get it slow. You pay while he's downloading free... :-\ :-\ :-\

could you be getting cross signals from another wifi connection locally?
check it using inSSIDer from metageek

Doubt it tbh, not unless they can break the encryption......and if i check usage on my isp's website...the only time theres a lot of traffic is when im downloading.....other times there minimal traffic.....

What incription are you using ?

If its WEP, it can be broken with the right bit of software  ;)

Best to use WPA2  :y
Its a lot harder to break  ;)

Just a thought  ;)

Its been ascertained that nobody else is using it. IF they were, his internet speed would be suffering ;)

For info, WPA has been broken as well, WPA2 probably won't be far behind.  Most people can't use WPA2 because many devices cannot support it.

According to my network card in my lappy, network authentication is WPA2-PSK / data encryption AES

If you're using WPA2, then it is very unlikely that someone is "sharing" your wifi...

Running at full speed, you should be able to transfer a 300MB file in around 45 seconds (assuming I have done my sums right), this presumes that everything is running very efficiently and it is the only traffic on the network at the time...

Just a thought ... what antivirus do you have, and how is it set .. on each machine ???

It is possible that the AV is scanning the file as it is sent on the "donor" machine, and the other AV is also scanning it on arrival on the "receive" machine.....  this could cause a slowdown in transfer.

Can you temporarily link the machines using Ethernet to eliminate or otherwise the wireless LAN?
