WiFi 4965AGN crashes during large transfers

Hello all



I have been having problems when my 4965AGN WiFi card has to handle large transfers e.g. system image backup from Laptop to NAS. Basically the network card crashes i.e. it does not even show in the device manager anymore and I have to reboot in order for it to appear and work again. When surfing normally everything works OK.

I do not think it is the router, since my girlfriend has a MacBook Pro and has no issues with large transfers (I tested this).



I have followed the advice on the following site:





Unfortunately no improvement so far.



My systems specs:

Sony FZ31Z

4965AGN driver version 13.4.0.139 with wireless-n mode enabled

Router WRT610N



Hope you can help!



Thanks
