Hi forum I resently got a new 1gigabit internet connection. After some investigating I decided to buy a ubiquiti edgerouter x to get the best performance out of it. After installing the router I was really disappointed, the router cut my performance back to 500mbit. Is there a way to improve my performance to 800 mbit. I know the I will not get the full 980 mbit, Which i get whiteout the routher. But 500 is way to low. Kind regards l, jknl
