I just got a MiFi the day before New Years Eve. Prior to that I was using a PC5750. I was on an unlimited plan which was previously Alltel. The local Verizon store talked me into a MiFi 2200 and said it would not affect my unlimited plan. In fact, my receipt specifically states "Unlimited".
Here's my issue - I live in a fringe reception area, but generally have had little problem with signal strength. The MiFi 2200 is running at about -85 dbm for EVDO. When at that level, download speed is about what I was getting with my PC5750 and is satisfactory. However, in the last couple of days, while on-line, I am noticing very frequent drops into 1X speed or less. When I check signal strength, it has dropped to around -115 dbm for EVDO. But, if I disconnect (using the internal web pages) and reconnect it goes back the around -85 dbm. This is happening very frequently - every 5-10 minutes. And, every time, reconnecting brings it back to a useable signal level.
Has anyone noticed this type of "control" or should I be looking to swap out my MiFi for another new one?
