Zyxel LTE4506 really slow in 4G+

Anarianthe

Hello,

I recently bought a Zyxel LTE4506, and run in some problems, probably related to 4G+.

Indeed, most of the time, the device is connected in 4G (network type: LTE, signal level arount -80dBm). I get fairly decent results (50-90 mbps down). But sometimes the device connects itself in 4G+ (network type: LTE_CAT, signal level -92dBm) and then, results go down to 0.33 mbps so basically... around 150X slower and unusable.

I can also force 3G usage (cellular network mode -> 3g), but then performance is quite poor (10-15 mbps down). 

Any idea to resolve this issue?
