Instant On - Wireless

Hello, we have around 150 AP's in our organization, primarily AP22's.  Starting around a month ago we saw wireless performance intermittently degrade significantly.  We've been able to narrow it down specifically to HP Probooks containing 8852BE realtek cards connecting to AP22's.  In our troubleshooting, adding a usb wifi card eliminates the issue, but so does connecting to another brand of AP.  The issues all started right around the time firmware 3.2 was installed in our Aruba environment.  The current driver version of the wifi card is December, so it is possible that that update caused the issues and not 3.2, but the timing seems to point to the 3.2 update.  There doesn't seem to be a way to rollback firmware on Aruba instant on so I wanted to get this reported in the hopes it can be resolved.  Its the base wireless card in HP Probook 450's so I'm guessing a lot of organizations could start seeing similar issues (and may not be able to narrow down the cause as we did).

Also if anyone has any suggestions for remediation, I'm all ears!  

Thank you

Hello,

I have the same problem. For me, it's the AP22s (about 40) that are faulty. I have HP Probook 450s with Intel Wi-Fi cards, no problems, but I do have Realteks.

I also have this problem with some Samsung tablets and some Lenovo PCs.

And when I replace the AP22s with AP12s, there are no problems.

I switched from Aruba to another brand, and now I have no problems.
