We understand you're having wireless performance issues under Windows® 10 Creators Update, in a dual boot configuration with Ubuntu*.
Did you manage to roll back to Aniversary Update and stay, or are you back to Creators?
The 19.60.0 PROSet drivers address issues reported on dual boot configurations. It's also possible that the issue is being caused by Creators Update, independed of your dual boot.
For future reference, could you please download and run the Intel® System Support Utility. This software will scan your current hardware configuration and settings then save them into a report.
