I do understand the inconvenience of encountering this type of issue and I have some questions about it.
I see the above driver file version; however, would you please verify the driver version shown in Device Manager?
Can you provide a description of your network environment, like a network map?
Did you test this connection using a different system?
Is this wireless driver version the same you used in Windows* 8? Did you test with an older version?
No, this is the latest driver for 8.1 I downloaded from intel website.
The problem was on going since I updated to windows 8.1 last year. I tried several drivers that came out since then.
I also tried deleting it and using the old driver that shipped with MS windows. Same problem.
Let me investigate further. Please stand by.
