Yesterday it struck me I was using a less secure wireless setup while the more secure was just a simple configuration change away. While adjusting the configuration I noticed the software version was pretty dated because my last IOS update (12.4.24T1) was from May 2009. To stay current I decided to upgrade my home router.
12.4.24T8 is the latest IOS in the 12.4T series. This version was released on 19 September 2012. I don’t have enough flash capacity to store the new 15.1.4 release, so I will stick with the 12.4.24 release. So I downloaded c870-advipservicesk9-mz.124-24.T8.bin from Cisco.
I have described the steps below so it will be a walk in the park next time.
