Issue seen on Flame 2.2 and Flame 2.0.

Streaming video does not continue and has network error when watching on hotspot, turning off hotspot, and then returning to Wi-Fi connection.

This appears to break Wi-Fi. It does not only affect the youtube clip. Attempting to use Browser/Rocketbar to search internet does not work after following steps above.

Comment 3

[Derek Harris [:DerekH] - Dont need info. Last day 6/5/15]

[Blocking Requested - why for this release]:

Nominating to block on 2.0 for this. The wifi will show in the status bar, and in the settings app as being connected. However, when the user tries to use something that requires an internet connection, it will behave as if there is no internet connection.

2.0? is a bit too late, and there is a recovery mechanism mentioned in comment 2.  2.1? is also tight on blockers, so going to move this out to 2.2?  this also seems to be specific to RTSP, so need the RTSP team to chime in.   it's also not a regression.

Comment 5

[Vincent Chang[:vchang][changyihsin]]

If I saw the repo steps correctly, it's connected to Youtube server not RTSP. So I don't think it's the problem related to RTSP. 
BTW, I can't reproduce the problem on 2.2 following STRs.

ni Jeremiah to confirm Comment 5, it's not reproducible in 2.2 now.

Comment 7

[Jeremiah Lee]

Issue still occurs on Flame 2.2.

Streaming video does not continue and has network error when watching on hotspot, turning off hotspot, then returning to video. Wait 3-5 sec when returning to video.

Note: This appears to break Wi-Fi. It does not only affect the youtube clip. Attempting to use Browser/Rocketbar to search internet does not work after following steps above.

Hi Jeremiah, I still can't reproduce the problem following steps in description above. Where can I get the image you are testing from? Do you use same flash tool from [1]?

Per offline talk with Ethan, he can help to track this bug.

Comment 10

[Ethan Tseng [:ethan]]

I followed the STR in comment 0 using Flame 2.1 and 3.0.
But I cannot reproduce this bug.

After I turned off Wi-Fi hotspot manually, which automatically turns on Wi-Fi connection,
I can resume playing youtube video without seeing any error message.
