Hmmm..... This is interesting. I've personally never used SyGate, but it appears it may be some sort of NAT software. This NAT software routes traffic, just like your router does. SyGate seems to be a software implimentation of NAT, as opposed to your Linksys, which is a hardware NAT box. Also, SyGate appears to also be a DHCP server. This may explain the multiple IP blocks that have been appearing, although now we have a third IP block invovled - 192.168.1.1 (linksys), 192.168.0.1 (unknown source) or 192.168.2.1 (unknown source). This is getting more complicated and its difficult to account for everything that may be wrong or right, but I'd start by disabling the SyGate software because its complicating things and is at least partially responsible for your problems. Were you aware you had SyGate installed and were you aware of what it does? Is it possible your ISP installed SyGate so you can share your Internet connection? If they have installed it, you may want to talk to them about its role in their setup and if it safe to uninstall it and use your own router instead. About those two extra IP blocks popping up... Is it possible SyGate is on both computers? Each of your computers may have its own IP block and is trying to be its own gateway/router. So this would explain the unexpected gateway addresses and IP address, if that's true. You should be able as long as your Internet service is DHCP (This is unrelated to your DHCP server issues). If it is PPPOE, you'll need a user name and password to login. If your service uses a static IP, you'll need to know what your settings are. Your ISP will know what type of service you have if you don't have this information written down etc.. If you have PPPOE or Static IP Internet service, this would explain why you're unable to connect to the Internet after resetting the router and trying directly with your computer(s). Of course this could also be because of other problems, such as SyGate being installed. The best thing to do is contact your ISP (as horrible as they may be) and ask them what kind of service you have... PPPOE, DHCP, Static IP or some other proprietary service. Then ask them what configuration is required (PPPOE needs a user name and pass, and Static IP needs an IP, subnet, gateway & DNS info, for example). With this information, we can make better decisions, as some things are a shot in the dark since we don't really know how your service works.
