I was plagued by that stupid security notice until I decided to do a hard reset. The security notice pop up stayed away for about a week before it came back again. I searched all over the internet to see if anyone had discovered a permanent cure. My searching came up with nothing. I finally decided to try the Software Repair Assistant (SRA). This is like a hard reset with the exception that it re-downloads the current version of the android software and installs it back on the phone. It does back up your contacts and apps before it wipes the phone and then re-loads the current OS (it does put the contacts and apps back on the phone). If you decide to do this you may want to download the new version of Kies (Kies 3) and let it do a backup before you do the SRA. The SRA does not back up as much as Kies does. So far I have not seen the security notice pop up, but it has only been a couple of days since I used the SRA.

i hav etried different routers with different wifi bands also. a same galaxy s3 with android 4.3 is giving good speeed unlike this .
so everyone please be aware of this when buying and let me know any solution.
My security update was failing as soon as I'd click it. I just did the same thing, held down on the failure notification, deleted the cache, deleted the data. As soon as my phone connected to wi-fi, I got the error, but THIS time it finally let me update the security policy. Hopefully the errors will stop now, but so far so good.
