My 4g service which I have been using for the past year became "not available" on my mifi log. I have called V several times and most techs have tried to evade the antenna issue and blame my equipment ETC...
The transmissions have reverted to 3G for the past 10 days and last night it fell to 1X for a short period of time and then returned to 3G.
I have a IPAD so just to try and nail down the problem I decided to take my IPAD and MIF router in my truck and turn on logging to map coverage in my area and capture screens of the log as I moved around the area.
What I found is that I can pick up a 4G signal within 2/10th of a mileonly in the northeast quadrant of the cells area. I drove around the southern arc of the towers general area and the only transmission was 3g. Even directly under the tower there was no 4G transmission.
When I returned to the northeast quadrant 4g came on again.
I was able to find a person in tech support who asked me to compose a email of the logs with info about when and where etc.
I sent the complete email to her and she responded that she had forwarded it to the network dept for analysis.
Have not heard back yet..
BTW... THe 3g logs reveal that it is in a special roaming mode 64.... whereas in 4g roaming is zero.....
So as of now I am not happy at all......
