Test the speed with out the wifi router in the mix. Connect a wired PC to the modem and speed test there.

Please post a copy and paste of the modems connection status page.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.

Be sure to power OFF the modem for 1 minute them back ON.
