I have a Jetpack MiFi 6620L and my signal(RSRP) is -110dBm. There are usually 2 signal bars. The speed doesn't seem any better than my old DSL. Is -110 normal? Would some kind of antenna help?
SNR should be a positive value. A negative value means noise is overwhelming the signal. Try dropping back to 3G: login to the device at http://my.jetpack or http://192.168.1.1 and navigate to Jetpack Settings > Advanced > Networks > Cellular Data > Preferred Network Technology. Note the current setting and then change it to CDMA Only and Save Changes. If you can, check About Jetpack > Diagnostics for the signal level.
I’m not expecting this to work better, but there is a chance that it might. The solution may be an external antenna.
thanks for your help. This seems to help the speed a little. I may still invest in that antenna. There is no SNR value now and the signal this morning is about -90dBm. I do have a steady 3 signal bars. Again, thank you.
