I have sever using my MiFi, Have been working fine on 4G until 2 months ago, has been degraded to the point I have shifted to 3G to work. I have had many trouble calls with Verizon and no one can answer why, I am in a marginal area but like I said I have been working at 4G for over a years, now it is so bad I had to shift to EDVO 3G. The help desk has no answers, one tech said it could be a Governmental reg in place to throttle the internet in my area. I do not have any other option since DSL is to slow and I use a VPN so Sat Internet is not an option. Any body has any ideas?
