Everything else on my iPad is humming along great. We have four devices in our home (two iPhone 7's and two iPad Air's). All three of the other devices are connecting to our wifi well, and the speed test shows the download and upload speeds are right there with our capacity. However, my iPad Air doesn't have enough speed (or connection, or how ever I should say it) to even run the speed test most of the time. When it runs the test, the upload speed is like 0.01. I have turned off/on the iPad, I have closed out all open apps, I have deleted and reinstalled the Ookla Speed Test.
