Was using my ipad 2 via home wireless and hotel wireless with no issue. Can play games connected to internet and streamed videos with no issues. Suddenly last night, the wireless speed slows down tremendously. Want to use speedtest app to test also cannot. Cannot connect.

Already turn off and on the wifi on ipad but to no avail.

Also turn off and on again the ipad as well to no avail.

What do you think is the issue here?
