Wireless-wired based devices must be in the...

If you are connecting to the internet, your network must use an un-assigned sub-net. You should use 192.168.1.1 - 255 with a mask of 255.255.255.0. Your router, linksys, will defaut to this. You should use dynamic addressing on the computers you want to connect, unless there is a reason that you need to use static addressing. If you need to use static addressing, you need to configure your router to only use say 192.168.1.10 - 20 for dynamic addressing. then configure your PC's to use 192.168.1.11 & 12 or anything else outside of the dynamic addressing.

I suspect your router is set for dynamic addressing and the static address that you are trying to use is in the dynamic range and your router will not see you PC's.
