Home network, linksys router trouble? - direct tv dvr removing history

I have a Linksys router. I have a cable modem. Originally there was a dispatcher for the cable, a DVR / TV tuner, one for the modem. something happened, and that the modem has stopped receiving a signal. I pulled the division and the direct connection via cable modem. When it is all the modem lights up green. Still no internet. I remove the direct link router and a modem for PC. i get internet. Now I know is this router. i re-enable the router to access objects. I set all the values. I wanted the little button for 30 seconds, all the original information is gone. Ive done it twice, and I can not have the WAN IP address will be valid. no matter what I always say expired. There are many options in this section to the router. It is a trigger button and a button-renewal and that's all.any help would be great. not necessarily corrupt, know I am in a computer. can not understand. Thanks
