[Connectivity] Signal Levels

$

This morning I was unable to get online. I didn't take a screenshot of my levels then, but my PowerLevel was -9 to -10 dBmV. After I removed the -3.5dBmV splitter for cable modem & TV, I was able to get back online and here is a screenshot of my levels. [att=1] I have a tech scheduled for tomorrow. It's been really hot lately, and I think that might be affecting the signal. I thought -9 to -10 dBmB was still "acceptable" to connect? Here's what I don't get. Here is what my modem lights look like: [att=2] Lights 1, 2 & 3 go solid (2 & 3 are blue). Light #4 just blinks and never goes solid. If it's able to lock into the downstream and upstream, what is light #4 doing? -- CheckSite.us | YourIP.us | Reverseip.us
