For the sake of anyone having similar problem, I spoke to linksys in the end and the key renewal is changing the code that someone would see if they attempted to 'hack' the network. The ACTUAL code stays the same. The reason mine had changed was because i had touched the WIFI protected setup button. It 'works' and is not changing the key every 99999 seconds as feared. I put 'works' in quotes as the annoying box keeps disconnecting but that most likely due to being in Jakarta, nothing works!
