We are seeing more and more clients having issues connecting to the internal wireless network. Recently my computer has become a victim of this too. When trying to connect, the windows client just hangs at "Validating Identity." I originally thought it was a density issue as when I added AP's to certain areas, it seemed to fix the issue. There are some areas; however, that only have 5 clients and the issue is still prevalent. I did notice consistency in one building where the people who could not connect had new Dell 6400 laptops and they were trying to connect to 1231 AP's - the new 1242 fixed their issue.
I am using a Dell Latitude D630 and I am trying to connect to a lightweight 1242. I set up netsh on my laptop, please see the attachment with the results.
Please let me know what you think. This is becoming a large-scale issue.
