For four months, I've had ROCK solid wifi performance from my IPad. All of a sudden, netflix stutters (or plays in choppy low-rez), apps take forever to download/update, and syncing takes several hours. Internet speed seems to be less than 1/10 the speed I was used to getting.
There are no newly added wifi devices in my home. None of my other devices have suffered this decrease in speed.
I've reset the wifi, and that didn't work.
