incomplete internet?

Maybe try clearing your DNS cache:

1. Turn off all of the devices using the modem (all phones, iPads, computers, etc.)

2. Unplug the modem's power from the wall socket.

3. Wait a minute, then plug the modem back in.

4. Wait about 5 minutes after all the lights on the modem are back on, then turn all your devices on one-by-one.

Email issue may be something unrelated. The streaming issue was caused by a corrupted DNS cache entry that propagated across your LAN. In general, if something isn't working correctly, try to immediately reboot the modem before it propagates across the network and is picked up by peripheral devices. If it still doesn't work, if can be rectified by doing the procedure maratsade provided, which also clears the bad entry on those peripheral devices.
