I found my EM9190 module often takes about 1 minute to be fired up and ready to establish connection with computer,does any option i can set to accelerate the startup process? ---

In order to know which part is taking long time, you need to check “AT!GSTATUS?” on when it successfully registers to network after power on for example, in my testing on EM9191 with FW 03.10.07.00, it takes 30 seconds to register network after power on. ---

i can’t access it’s serial port after the startup process finished and when i’m able to access it already connected like this: !GSTATUS: Current Time: 128 Temperature: 40 Thermal Mitigation Level: 0 Reset Counter: 1 Mode: ONLINE System mode: NR5G PS state: Attached IMS reg state: NOT REGISTERED IMS mode: Normal IMS Srv State: UNKNOWN SMS,UNKNOWN VoIP NR5G TAC: \*\*\*\*\*\* NR5G Cell ID: \*\*\* NR5G band: n1 NR5G Carrier ID: 0 NR5G dl bw: 20 MHz NR5G ul bw: 20 MHz NR5G Tx Power: 20 NR5G Tx chan: 389980 NR5G Rx chan: 427980 NR5G dl MIMO: 0 NR5G ul MIMO: 1 NR5G(sub6) RxM RSSI (dBm): -54.1 NR5G(sub6) RxD RSSI (dBm): -53.5 NR5G(sub6) RxM1 RSSI (dBm): -58.6 NR5G(sub6) RxD1 RSSI (dBm): -52.9 NR5G RSRP (dBm): -85 NR5G RSRQ (dB): -11 NR5G SINR (dB): 30.0 ---

Do you mean the serial port is enumerated in Windows device manager one minute after power on ? This should not be the case then, I can have the port about 20-25 seconds after power on… ---

according to the product technical specification: ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/d/d68c71d9525d286c17302959e11909bc0476c3cf.png) ---

It turns out that probably hardware problems replaced with a new em9190 module,all fixed
