My Unifi 30 mbps just upgraded to 50 mbps 3 days ago. (Thank You Campaign 2017).

Based on 3 days speed test result, I only able to get 30/20 mbps on beta.speedtest.net. Download remains as 30 mbps, only upload speed doubled. Even watching 4K video on Youtube, only can reach max bandwidth/speed around 30 mbps.

I am using Huawei HG655a with TP-Link Archer C3150 V2, my router has built-in speed test. The built-in speed test shows 50/20 mbps. But I still get 30/20 mbps on 4 desktop/laptop computers in house.

Any idea how to solve this problem?

LAN Cable/WiFI (2.4g/5g), Mobile/Laptop/Desktop all tested, same result, 30/20 mbps.

Restarted multiple times, tweeting with TM supports on Twitter since yesterday, tried almost everything on my side, also refreshed connection on TM side.

Still 30/20 mbps using cable/wifi. But 50/20 mbps shows on router administration page.

Found the answer on

It was the QoS that caused the problem.

I was using gaming setting, now switching back to standard setting.

Finally can get 50/20 mbps on beta.speedtest.net.

Thanks to jusbella.
