Not sure this is an issue but....

I'm running a wireless network on a Linksys E3000. I run a motel and provide access for the guests via wireless network. I also have 2 computers for administration & staff that are hard wired through the router. I've had this setup going for years and even more years before that with an older router.
Of course the IP is the everyday router 192.168.1.XXX. Now, since a few days ago the 2 hard wired computers have the IP 76.178.24.249. The router's DHCP client table still shows the old IP. Both computers have different IP's in the table but the exact same IP now.

Windows 7 pro x64
ISP roadrunner (Time Warner)
Linksys E3000, 2.4Gh band for everyday use & 5Gh for the 2 "private computers"
What's going on here? Should I be concerned or what?
Nervously await response. Oh yeah, ipconfig output attached

The IP shows as 192.168.1.119, where did you see the 76.178.24.249?

It's never a good idea to run your company computers on the public network. You should subnet your network - one subnet for your company computers and another for the guests.

That IP shows when either of the hardwired computers does a "what's my IP" search (Google, Bing, whatever). My 2 mobile devices show an IP from the router, of course. I'm not too concerned about the admin computer's security. Never had an issue yet. I've had kids try to hack the network but none have succeeded yet. I use strong passwords.

What Google is showing you is your public address, i.e. the one assigned by the ISP. If you want to learn more about this, google "network address translation".
