The 192.168.... range isn't likely to exist for you as you've set the router to bridged mode - you've essentially said that you want your PCs to be on the same network as your ISP that your router is on, rather than saying that your router is on the ISP network and is also on the internal 192.168.x.x network. This will therefore not created the extra, internal network for your PC to join (which would have been on 192.168.x.x).
Assuming that the modem is plugged into the router, and your PC is in turn using the router as your gateway...... when you do "ipconfig /all", do you see an IP for your own machine? If not, you are probably limited to the one IP on that network which will be assigned to your router. You might want to reset your modem to get it back to the old settings so that you can configure it again.
