Hello,
i need new AT commands AT+QNWCFG="lte_mimo_info" and AT+QNWCFG="nr5g_mimo_info" introduced by Quectel of FW version RG501QEUAAR12A09M4G_04.200.04.200
So when I already need a newer FW, I immediately put the latest one.

Hello,
I sent a ticket two days ago via that link, how long does it usually take for a response?
Thank you

I apologize for the delayed response. I have already sent you the instructions. You should have received them by now. Please let me know if you haven’t received them.

Hello,
I got the instructions, thank you very much 
The internal modem firmware upgrade took an incredible 12.5 hours!
On a 200/100 Mbps internet connection.
But it was successfully done.
Hello,
I’m glad the update was successful! However, downloading the firmware update shouldn’t take this long. It might be due to network congestion on the modem updater server. I haven’t seen it perform this slowly before.
Best regards,
