Network doesn't work fine after a load.

Hello,

I have a problem on my iMac 2011 (20go ram) under windows7.

Whan I start my computer all is fine. The network is fluid, I can go on the internet, on my server...
After loading two 3dsmax sessions, one photoshop sessions and transfert some large files (near 1go) -> my network goes wrong.
The browse/save/open/transfert operation on any application takes a loooooooong time to start (maybe 20-30s).

Could someone guide me through an analyse process to find and resolve this problem ?

Regards,

It is a problem with the Mac hardware. This is common for Mac computers. Go to the Apple Support forums and take a look at all the networking problems. Look in the Boot Camp forum for a solution, if there is one.

A lot of reported problems seem to be related to the wifi network and connections.
My disagnostic is different, the network is found, I can access everything (internet or lan) but the connection time is so loooong.

I am here to get some expert help before posting to mac forum because there is far less expertise there. Especially on bootcamp forum.

I would like to check with the system monitoring tool from windows, but I have no method of investigation. Could someone help me on that ?

I have just upgrade my driver to 15.4.0.17

Verdict in few hours...
