I recently purchased the 655 to replace an old Linksys wired router. I had my system set up great with the old wired router, when I moved, I bought the 655.
I can get the internet on my HTPC and another pc I had wired to the 655. I can connect to Xbox live with the 655 but it will not allow me to connect to my HTPC.
I also have a DMA-2100 media extender that I can use wirelessly without problem (stutters when I watch HD programming).
When I enter the 8 digit code to add an extender the blue and yellow shield appears by the next button. Do I need to change a setting on my HTPC?
