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?
