Last week I started to notice that connecting to websites had gotten slow on my Google Pixel 2 phone and it kept getting worse over time. Finally, yesterday it would not connect at all. At the same time both my iPads connected normally. These are the steps I did in my attempt to get it reconnected. If you are having this problem I recommend reading all steps before proceeding

- Shut Wifi on the phone off and on
- Shut the phone off and on
- Forget Wifi-setting on phone
- Turn the router off and on 
- Factory Reset the phone
- Reset the router

None of the first five steps made a permanent difference. Resetting the router has worked and now my Pixel 2 is now connecting to the internet fine.
