On the task bar the icon says "Internet access" but this is not often true. No internet. No email. Simple programs like WordPad open slowly or not at all. Solution: Shut down. But it won't shut down normally. It just hangs. I've even waited overnight. I have to do a Manual Shut down. I unplug the moden and (wired) router. Turn off computer manually. Turn on modem--wait. Turn on router--wait. Turn on computer. Problem not solved. Repeat two more times to get the computer online. Google Chrome is slow to load. Send, in Thunderbird is very slow. Working say in Photoshop or just WordPad I get a "Program not responding". I try Task Manager. It can't close the programs. So again, a manual shutdown.
My cable modem has as its appropriate Target Commissioning Range: -2.5 dBmV to +2.5 dBmV However, it's actual reading is:
Freq/Power: 573.000 MHz 4 dBmV
Freq/Power: 31.600 MHz 42 dBmV
Does this indicate that the modem is getting too much "juice"? If so, my problem might be solved next time I call Comcast. They always fix the modem from their end to the point that I can at least get online and email. But the connection is always slow. Not one of the Comcast people knows knows that I've called about the same issue many times. Should I ask for an in-home technitian?
These are my own thoughts, my own research. I really don't know what it is. I'm just guessing.
Suggestions will be most welcome and much appreciated.
