I have Virgin 108Mb broadband. It tests at 108Mb/s on both desktop ethernet and laptop Wi-Fi. It also tests at 108Mb/s on my mobile through a speed test app. But the problem occurs when I test the speed though any browser on mobile. When I start the test it seems to start at full speed (around 100Mb/s) but only momentarily, then the speed quickly drops down through the test until it reaches about 30Mb/s. If I test it a second time, the speed starts slow then increases but only reaches around 19Mb/s.
I have a Huawei Honor 7.
Any ideas what's happening here?
