Hi Syed,
Thanks for taking the time to post here about the issues you are having with your speeds.
After upgrading, it can take 24 hours for everything to go through correctly.
Based on your results, it sounds as though either you're testing the speed to the device via WiFi or there is something limiting the speed on your device.
As it's been over the 24 hours now, can you reboot your hub and check on a few different devices? It will also help to get a speed test done on a device that is connected to the hub via an ethernet cable.
Let us know the results you get.
Many thanks,
