Satechi USB-C Hub interfering with browser function

I have recently been experiencing problems with my browsers not being able to access the internet until I disconnect my Satechi USB-C Hub. Its strange to watch as Safari boots up and tries to reach the internet but the blue progress bar stops part way. There will be no further action until it times out unless I disconnect the Hub at which point it immediately connects. After this I can reconnect the hub and browser operation is normal. Happens to Firefox as well.

I am using the 2017 Macbook Pro, 10.13.6 (High Sierra).

I have recently reset NVRam and SMC.
