KB2840149 released - "fix" for KB2823324?

I had no problems with KB2823324 but installed KB2840149 over it (not having read the advice to uninstall the former first). Since then, my WiFi has been cutting out frequently, such as when the computer goes to screensaver or comes out of standby. I uninstalled KB2840149 today and am watching to see if the WiFi problem is resolved. Would like to know if anyone else has had similar odd WiFi behavior.

(This PC never had a Kaspersky product but had Norton IS preinstalled, removed w/ removal tool but lots of Norton crap left behind.)

Update: I uninstalled KB2840149, then uninstalled KB2823324. The wireless was then acting normal for 2 days but the problem reappeared, so it was most likely a coincidence that it began the day I installed KB2840149
