Issues with obtaining fix

Hello, I have issues with obtaining a fix with the reach. I let the device attempt to communicate with the satellites, but after an hour or so I am unable to obtain a fix with the suggested configurations provided by Emlid. The best I can do is get a float. I am worried to integrate the device with my octocopter due to inability to get a fix. Is anyone else able to get a fix with altered settings? How important is the scenery?
