Hi,

I have upgraded my line from 100 Mbps to 750 Mbps yesterday (asked T-Mobile webcare via Twitter).



When i got the confirmation from the T-Mobile system that my subscription was updated after a couple of minutes a could use my new speed. But i was been told that the processing of the adjustment of the speed could take 5 working days, so i think i have been lucky.



I advice to wait a couple of days and see, if 5 working days are past and your speed is not adjusted to contact T-Mobile support again.



Have a nice, weekend.

Hi Sidyk, I checked your speed for you and the upgrade to 750 Mbps has been performed! If you're still only getting a maximum speed of 100 Mbps then try testing it with a different device and a different ethernet cable. You can also perform a speedtest with WiFi and a cable to see if the WiFi speed is higher. If so then it's almost certainly a hardware problem. Not all ethernet cables are suited for high speeds and older network adapter sometimes also have problems. If you're using a suitable cable (preferably cat6 or higher) then you can also change you adapter settings as follows:



Change your network adapter to a static 1 Gbps full duplex

o  Search for the 'Network and Sharing Center'

o  Click to the left on 'Change Adapter Settings‘

o  Select the adapter through which you're currently connected

o  Rightclick and select ‘Properties’

o  Click on ‘Configure’

o  Under the ‘Advanced’ tab activate 1.0 Gbps full duplex
