I know they all had problems dropping the 4G when connected to the mobile hotspot, but apparently according to everyone at Verizon Wireless, it should be fixed now. Well, I am continuing to have the problem. Every time I connect to my 4G hotspot with my 2011 Macbook Pro, it droppes the connection after 5 or 10 min. Yes, I have all the lastest updates and they have sent me two replacement devices. What should I do or what are my options? I purchased the phone brand new in August, so it is still well under warranty.
