No change even after installing and rest allying with the new disk. I even did a defragmentation and a virus scan on my computer with no virus results. I watched the demo for the speed test and it stated that with 3G broadband a good rssi is -80
And 4g around -60 ....my 4g has been showing between -78 to -80 and when it disconnects it drops to 2g then to 3 g and I cannot go anywhere .i have to turn off the vzacess off and wait a few minutes to get 4g with no bars for about 10 minutes.
This is now after a new sims card and a disk the same problem since March 29
