Problem with Videos both browser and other apps

I searched through the forum to try and find answers but had no luck. Long time pb owner and love it. ok running latest developer 2.1.0.xxx os. The other day I tried watching a youtube video but the video never started. I thought nothing of it and kinda forgot. yesterday I was on crackberry and other websites and tried to play a couple of videos they didnt play but also frooze up the browser. I tried using simple browwser same result. I then went to tablet tv app nothing. video doesn't play and freezes up whatever app I am using. very frustrating.

Things I done
soft reset
hard reset
cleared all browser cach
restarted browser and playbook many times
turned private browsing on and off a bunch

I could really use any suggestions and would really appreciate it. not sure what to done. thanks

Downgrade to the official OS?

Another post earlier said more or less the same thing & they was on the beta playbook OS.

Depending on what type of router you have (mine is a D-Link DIR-601) I went to Settings-Wifi-Saved Network, opened the network, went down to Band Type and switched from Dual Band to 2.4 GHz. My router and PB seem to approve of this change.

I fixed that issue by doing a wipe and reload.

Be sure to do a back up with the latest DM software first.
