Hello. I have a old Droid 2 that I have owned since it was first released. This past month, the phone has stopped sending pic/video messages whenever I am connected to my home wireless network. I haven't changed any settings on my phone or home network, nor has any of my equipment or service contracts changed. Right now, the only way I can send a pic/video message is to physically turn off wi-fi and resend. What are some things I should look at or do in order to correct this?
