If you do, when the tech shows up, be sure to let them know if discharging static fixes the problem, as it's a giveaway as to what the problem is.Data effective. The problem may, of course, be further back in their network and you'll have to call in a help ticket. Use only carrier grade passives outdoors, but also ideally indoors buy the brands Comcast buys (Antronix, Extreme Networks, Blonder Tongue, etc.), NOT Dynex or Onn or whatever big box store brand. If that fails to fix it, check on the outside wall of the building for any splitters you can access just on your own property, and replace them with the exact same part number from the same vendor. If any splitter was the problem, replace it. Temporarily remove unnecessary splitters indoors 1 by 1 until the problem goes away use line extenders which do not split if you need that to get the cable length you need. In every such case, the FIRST thing to do, if there isn't another obvious problem like frayed or damaged cable, should be to replace every splitter in the path. Physically discharging the line by touching the center conductor of a cable to a grounded metal surface (like the outside of the cable jack on the modem itself yes, it can spark!) can help for a few days, but the cause is likely to build up again. In a lot of cases, there is static on the line from bad cabling or more commonly defective or lightning-damaged splitters and passives. Reconnecting, of course, will not always fix the underlying physical condition causing poor upstream performance. That will likely cause the CMTS (headend) to stop listening to all but 1 of them to reduce interference, slowing you down, and if the cause of interference continues, your modem will probably exceed the 58 dBmV absolute limit and have to reconnect. Contrary to what that page says with 55 dBmV, anything over 51.5 dBmV is cause for concern on a modem using multiple upstream channels (which is all of them these days). That increases interference with other customers, and eventually you hit a limit and are not allowed to transmit any louder. That means the other end couldn't hear you clearly, so the modem started talking louder. In the upstream direction, it is far more common and worse for the transmit power to be too high than too low. That's why the numbers are so different.) The opposite is true of downstream: you don't see the real transmit power, so you rely on receive and SNR. As the page notes, you don't see the real upstream SNR, or the upstream receive power, so you have to rely on the upstream transmit power. (Keep in mind the things your modem sees and the thing Comcast sees are the opposite stats for each direction. If your levels are beyond this range, you will likely see frequent disconnects or modem reboots." Will emphasize this in the page you were linked: "Upstream Power Level: This should be between 35dBmV and 55dBmV.
