All of a sudden I’ve been getting terrible speed on Fios gigabit connection. Went into the network map on table mode and see that the link speed of internet is 100mbits. All 4 ports are 1000mbits. This just happened out of the blue and I have no idea how to fix it. I’ve tried rebooting everything multiple times. I’ve had this router for about a year now and never had this issue. Any help would be appreciated.
Go to Device Manager, open the side menu and go to the Table view. You should be able to see the current max speed for each port. If your port is listed as 100 instead of 1000, it could be because the cable you're using isn't fast enough.
