Sorry, it is a big misunderstanding.
As mentioned previously the driver which caused problems came even from the 14.x package.
I double checked it a minute ago, exactly said it was driver from 14.3.0.6.
I doubt it is rather specific. If to do a web search lot of people complain
severe problems with Intel driver; do not remember now the exact version.
My question is still open and valid
What are the known bugs of device driver version from Intel WiFi Proset software package 11.x?
What is the latest driver version/release working well on Vista 32Bits (Intel WiFi 4965 AGN)?
Nobody than Intel will know the best answers. Otherwise they are no worth the acceptance on customers side.
