iPad Pro WiFi issues

I recently updated my iPad Pro to run iOS 11.2.6. Again, I didn't have any Wi-Fi issues and have not noted any significant improvement with either Wi-Fi connectivity or performance after doing so.

What I would suggest that you try, if you haven't already, are the following, in order:

1. Restart you iPad. Restart your iPhone, iPad, or iPod touch - Apple Support
2. Reset your iPad's network settings. iOS Reset Settings Explained - Redmond Pie
3. Perform a "Reset All Settings" reset.

How are you measuring Wi-Fi signal strength/quality to determine that the upgrade has caused performance issues with Wi-Fi? Does your iPad have this issue regardless of which Wi-Fi network it is connected to?

FWIW. No, I haven't noticed any perceivable Wi-Fi performance loss with my new iPad Pro.

Having issues - Yes from me. Mine stays connected to wi-fi, but the IP address assigned is out of range, and I lose internet connectivity. Unable to resolve, even with new routers.
