RM500Q-GL doesn't reach 5G on raspberry pi

I’m using RM500Q-GL modem, When I connect the modem to a windows laptop it reaches more than 800Mbps. But when I connect the same module to the Raspberry Pi 4 it only reached 100Mbps.

How to solve this issue? is this issue related to QMI drivers? then how can I get the latest driver for this modem?

I used the following commands to establish the connection

sudo qmicli -d /dev/cdc-wdm0 --dms-set-operating-mode=‘online’
sudo ip link set wwan0 down
echo ‘Y’ | sudo tee /sys/class/net/wwan0/qmi/raw_ip
sudo ip link set wwan0 up
sudo qmicli -p -d /dev/cdc-wdm0 --device-open-net=‘net-raw-ip|net-no-qos-header’ --wds-start-network=“apn=‘Mobitel’,ip-type=4” --client-no-release-cid
sudo udhcpc -i wwan0

Dear Sir,
Please contact our local FAE guys to provide the latest driver and tool for you.
If still not ok with the latest driver, they will help you to check, thanks!
