I just ran some test on several Galaxy Note 10.1 for wi-fi speed. The note looses wi-fi speed quickly after turning wi-fi on. I called support and they had me restore the Note to factory settings. Same problem! Samsung has a big problem here and needs everyone to complain so they will fix it. Here is a test that everyone with a Note 10.1 (or any Samsung phone or tablet) should run. From Google Play, download the app Speedtest.net Open the app and run the speed test several times to get a few runs in the history. Now, go to your settings and turn off wi-fi for a few seconds and then turn it back on again. Now go back and run a few speed tests again. I've had every device run about twice as fast after simply turning wi-fi off and back on again. My Verizon Note 10.1 was as slow as 2Mbs after setting for an hour. Then after switching wi-fi off and on I went up to 60Mbs. This is crazy!
