I haven't really had too many issues with my connections but recently due to these unprecedented times, my speed has dropped drastically to something that will not suffice. I've tried resetting the modem and have a rep do the same but my speed will not go above 30mbps. In addition, yes I'm using the proper model modem Model Name: XB7. I do have a 1000 Mbps ethernet card capable of handling the speeds. Before the pandemic, I was getting my speeds without any issues. After checking the checklist I don't own a Cat 6 cable but I will be picking up one tomorrow. It's weird Comcast didn't give me cat 6 cable with the modem they gave me.
