ISPs have to update FW. Users can not. Some ISP will not update user owned modems so you maybe out of luck here.

Please post a copy and paste of the modems connection status page.

Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
What is the brand and model of the host wifi router connected to the modem?

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly. Those errors your seeing your ISP needs to look into.

Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute then back ON.
