Nighthawk cm2000 connected to spectrum router. Wifi is marking fair in bedroom where desktop is

[IceCrack23]

I'm having issues with being able to receive good a good WiFi connection in my bedroom. I currently have a nighthawk cm2000 modem connected to a Spectrum router model (SAX2V1S). I do not have the biggest apartment so I'm wondering what could be causing this to have a poor connection? I have a buddy that just keeps mentioning to look for the best modem settings and to change them on my end. I have looked but have not found any answers to this. I am also not very knowledgeable when it comes to these things. It was suggested to implement a WiFi extender but i am curious to know if that is really needed. Any sort of help will be appreciated. I have provided an event log since it seems that's what a majority of people do. Firmware is V1.01.06.

There is no settings to adjust on C and CM series modems.

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