Need to get a better understanding of what isn't working? Can you access the router? Does it boot? Does it get an external IP from the network DHCP?
My guess is this: Since linksys default to an internal LAN of 192.168.1.0/24, you probably have the same internal and external LAN. Maybe the linksys doesn't like it.
Disconnect from the network. Connect your PC to the inside lan of the linksys. Your PC should get an IP from the linksys on 192.168.1.0. Conenct to the linksys at http://192.168.1.1 Change the internal LAN subnet to something else... like 192.168.15.0 just so it's different than the office lan. Save and restart. Connect it all back up. Connect to the router on 192.168.15.1 (or whatever you chose) and verify it still has 192.168.1.23 statically assigned on the outside. You should be able to connect though it now.
In addition, make sure you disable the dhcp service and wireless. Your organization's network team isn't going to appreciate it very much when your device issues IP leases to other network hosts on the LAN.
