How long does it take after upgrading Internet speed?

I upgraded my internet speed yesterday, but after 24 hours, it's still as slow as before.
I tried rebooting my modem, linking my computer directly to the modem without using Wifi. But the speed is still as slow as before.  I'm sure my device support multi GB speed and I'm using CAT6 ethernet line. 
Update: I fix the problem by reactivating my modem through xfinity.com/activate

Name your speed tier and your modem model.

Try calling 1-800-comcast and ask a rep to completely remove the modem from your account and to "re-provision" it from scratch. Also ask them to confirm that the provisioning and account data in their database is correct and complete and that the correct configuration / bootfile for your subscribed to speed tier is being pushed to the modem.
