A tech came out and said I had to tell my landlord. I do live in an apartment, but I have the wire maintenance plan. I do have an HD box, but the HD doesn't look as clear as it should. The cable is frayed slightly and I did a self install kit. I know what I'm doing, so should the RG-59 be replaced with RG-6? And will charter do it?
This may be beyond your control: When the tech told you that the landlord needed to be told, it appears that the cabling problem exists between Charter's entry point in the building to the entry point in your unit. Which is your landlord's territory, requiring your landlord to make the work request to Charter. Sounds like you've done all you could. RG-59 from the wall outlet to your cable modem is sufficient. You could swap it out w/ RG-6 but, because the run should be relatively short, I don't think you'll see enough of an improvement to support broadband. Wire Maintenance will only support what you have control over, which is from the wall outlet to any wiring in your unit. Now, your landlord may make the request to get Charter to do the fix, but you may end up having to pay for it unless Charter allows the work under Wire Maintenance. Good luck.
