Aurora R16, slow upload speed tests

I have 1G down and about 40Mbps up service with xfinity. Downloads are near 1G but uploads are about 4Mbps wired connection.

My other PC's connected wirelessly test about 700/ 30 for down/up.

When I switch Aurora R16 to wireless connection it's about 700/ 3 for down/up. Conclusion... any idea for the slow uploads and fix?
