Router Connection Problem

[Merfoo]

Our router keeps dropping packets. We have tested with 2.4 and 5 gHz and followed FRC router configuration guidelines with the FRC bridge configuration tool and manually. We connected the driver station directly to the cRio which worked. We alos connected the driver station to the router and then that to the cRio, which also worked. We have tested with multiple ethernet cables, computers, routers, and cRios, and also reinstalled wireless drivers. We used a 5gHz dongle which also didn't work. We have ran out of ideas to fix this problem any help would be appreciated.
