since you have a comcast modem the router should automatically pick up connection,since you have already reset the modem,what you need to do is to check whether you are going online suing the modem,once you can go online using the modem,reset the rotuer as well,connect all the devices properly(the cables should be in the appropriate ports)turn off all the devices for 60 sec and then turn the modem,wait for the light to be steday,turn on the router and then the computer and check if you are being able to go online i am sure you will be,incase you are stuck let me know ffurther...
