usb720 modem keeps disconnecting or going dormant every 10 - 20 minutes for the past month or so. Doesn't matter what you are doing. Have had for 2 yrs and it used to stay connected for hours at a time up to 24 hours now lucky to get 10 minutes. Noticed under usage in vzaccess manager showing connecting not with the static ip that I'm supposed to have. Was always connecting with my static ip address until couple months ago. I can still get my data to transfer to main office but is very frustrating having to reconnect all the time.
