I have a DLink N300 wireless router. I used the wizard to connect it. I noticed ruing the connection it said I already had a router but I went ahead and installed it. I am not sure but maybe the DSL modem has a router in it also. I took the internet connection out of the modem and put that in the router and then connected them together with the blue cord they provide. That was the instructions. Then the internet on the PC stops working so I put the internet cable back in the DSL modem and it worked again. The blue cord is the only connection between the two now. I can see the wireless network on my laptop and it allows me to enter the password information and then after it check the password it says it can't find the wireless network. I have tried swapping the cords differently and every time the PC connected to the DSL internet stops working. I need to be able to use both.
