Hi,
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
