Start simple and look at one thing at a time.  1st, did anything change?  No updates were pushed, no network changes?  Have you validated that your ap's are all joined and in the correct configuration?

Also, please state what equipment you have, the model number and code.  Also the end devices and if all devices have issues or if you isolated the issue with a specific device or model?

Well I think you need to revert your changes. Then hopefully you have a lab in which you can upgrade and test to determine what is causing the issue you have. Also whenever you upgrade, you should compare the configurations pre and post using a diff tool to check if anything changed or was added.

Is this only happening to laptops?  What about tablets and smartphones?

Hello Scott

Is good your idea but a dont have the equipment to do a laboratory, all my equipment are in production.

If your changes are causing an impact, then you should revert your changes.  If you don't, all you will be doing is experimenting to see what helps.  Making changes in production to try to figure out the issue is a very bad idea.  You also made multiple changes which is also not a very good idea since you didn't test and validate.  If you open a TAC case and tell them that you upgraded and made some configuration changes, they too will probably tell you to revert back.  What you can do is remove all the configuration changes you did and see if the upgrade caused issues.  If so, then revert back, if not, then the upgrade is okay, then make config changes one at a time and when a config changes breaks your environment, then you know what not to do.

And on laptops make sure all wireless drivers are updated to the latest version from the vendor.

Make sure smartphones are updated to latest version of OS.
