So I currently have 2 Mifi's at home and currently I have a issue with one of my devices running extremely slow. Both of these devices are located in the sdame room of the house but one of my MifI's outperforms the other by quite a bit.
Mifi "A" consistently achieves speeds in the range of 1.2 - 1.8m down and 300-600K up
Mifi " B" consistently achieves speeds in the range of 300K- 600K up and 100-200K up
Now I have gone through and done a factory reset on the device, mirrored the config of device "A", completed all firmware upgrades and have pulled the battery numerous times, I even swapped the battery with "A". Granted I don't expect much to change with the battery swap since the majority of the time it stays plugged in.
I have also tried a wide variety of PC's/Laptops and the results never change? Could it be that its just going bad and needs replacing? I have run out of things to try!
