X2 Gigabit Only Connecting at 1 Gigabit

I recently upgraded to 2 gigabit service. I've tested the connection to the XFI router and can see i have the service up to the router but cant get it to my desktop computer. I'm running Cat7 cable, Realtek 2.5 gigabit network card. I was connecting a100/100 then i forced the driver to connect at 2.5 gigabit full duplex, but still only connect at 1000/1000. Speed test indicate this is actual. What am i missing?   I have see other post with the same issue, but not the fix. Any help would be appreciated.
