wif modems

ok still trying to do this. so now i have anoter issue. i go the c3700 manual and it said i need to bridge the r6300 to the c3700 combo unit and to do that it said i have to turn off the router mode in the c3700 modem. i did that and the router still will not get me on the internet. i have the yellow portt on the router plugged into the #1 port on the modem. so what might be going on?  after doing this a number of different ways i tried turning off the router and the ssid on the modem and all i could see was my hime items. and that made me reset the modem a number of times. 

then today just for the heck of it i took the 6300 router upstairs and plugged the router into a network switch i have so i can connect my pc's to the modem. i was told i needed a network switch to connect multiple items in the modem and it works, however in doing that i unplugged my pc and it connected via wifi. then i plugged that cable into the back of this 6300 router into one of the 4 ports not the yellow port. and it then let me on the internet. but what i was trying to do was get the router to be by itself so i could hook up the network switch i have downstairs to it. i have a larger switch down stairs by the modem and a smaller one up by my pc.  

 this time i left the router mode switch alone and i was able to get on the internet. but then my cameras and phone would jump back and forth between both the modem combo unit and the r6300 router.

i had that before and was told to just get another larger faster combo unit. so i'm lost with this. it seem no matter what i try based on instruction i get for helpful people nothing works. the ip cam site told me i need to get a router that has the vpn on it but the router makers tell me they don't make them and then i find out you need to reflash them to get that service to work. the other forums tells me those are free on the routers. thas is another story just saying what i'm up against. so any help with this sure will be welcome. thanks
