Question

Please can anyone help me? We recently had 4g broadband installed and initially it didn't seem too bad but now it is very unpredictable and most of the time we are struggling to go on to the internet it is so slow.

The signal strength is -65 to -71, which I believe is good but even connected directly to the router it is so slow.

Hello, 

For this issue of yours i would recommend you checking the values of RSRP because it is not only the RSSI that matters. 
You can get more information on this link: https://wiki.teltonika-networks.com/view/Mobile_Signal_Strength_Recommendations#4G_.28LTE.29

RSSI for LTE is a calculated from several other signal related measurements: RSSI = wideband power = noise + serving cell power + interference power. For example, a 4G LTE modem might report an RSSI of -68 dBm, but:

RSRP = -102 dBm

RSRQ = -16 dB

SINR = -1.8 dB

In this case, the signal quality is actually very poor. This could be due to the device being some distance away from the LTE transmitter. It’s also possible that something is interfering with the signal, such as a building or other obstructions between the device and the tower.

Hope it helps
