I was notified by Verizon that the use of my older network extender was not going to be covered anymore and that I was going to have to upgrade to a newer version. I was to place an order for the newer model and to replace my older one. After doing so, the newer one has changed my time zone from the mountain time zone, Denver, to the central time zone, Chicago. This device is used in our vacation home in the Denver area, mountain time zone, and our home is located in the central time zone. Our iPhones are, and always have been set to automatically change zones and have always worked properly until I changed to this newer network extender. I have read that all that needs to be changed is to go into the settings of the extender and and to change the time zone to mountain time. Unfortunately this does not work, and seems to not work for anyone having the same issue. Am I just forced to change back to my older unit which has always worked? This to me seems like a ridiculous way to correct this issue! Please give us the simple solution and not by changing our iPhones to manually set the time zones each time!
