New Dell XPS 13 - Wi-Fi slow to connect after hibernation

Hi, I got the 2017 Dell XPS 13. Overall I love it, but one problem I'm having is that if I let it go into hibernation mode when I start it back up it refuses to connect to Wi-Fi properly. I usually turn the Wi-Fi off and on again, and then have to wait until it realises it's connected. I usually have a tab open with google loading, just so I know as soon as it's connected again. This takes about a minute or so...

This seems to be on any network. The icon suggests it's connected (i.e. it's not still saying "connecting")...

Any help would be greatly appreciated, thanks!
