problems updating firmware C7800v2

[hugsss_2000]

I have the nighthawk c7800v2. I have had it since February 2021. My isp is mediacom. I have connection issues ie get dropped from the internet but able to get right back on easily. a tech came to the home and checked everything inside and out and said everything is fine. my nighthawk app says i need to update my firmware but when i attmept this in the routerlogin it is not an option for me. I read in another thread that the isp needs to do it but my isp says they do not have access to modems that are not theirs and i need to update it. according to routerlogin.net my firmware version is V3.01.40. I do have geek squad coverage so i am going to check with them if they can help but thought i would see if anyone had suggestions here. 

what do i do?

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 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.

This is a list of FW versions vs model# vs ISP:

Users are not allowed nor is support for user manual FW updates on C an CM series modems. ISPs have to push FW updates. FYI, some ISPs will not update user owned modems. Users will need to contact the ISP and ask for more information regarding this.

can you direct me where to find the connection status page?

1. Launch a web browser from a computer or mobile device that is connected to the
modem router network.
2. Enter http://routerlogin.net or http://192.168.0.1.
A login window opens.
3. Enter the modem router user name and password.
The user name is admin. The default password is password. The user name and
password are case-sensitive.
The BASIC Home page displays.
4. Select Cable Connection.

Power levels are too high:

You have too much Correct and Un-Correctables that should be mostly zeros. Need to check the coax cable line for kinks, fittings and any splitters. 

Not all channels are locked in. This depends on your ISP speed package. What Speeds UP and Down do you pay for? 

Check the events log as well If any Criticals or Errors are seen there, the ISP needs to review them and help resolve them.
