Take a look at how your connection is set up.

Make sure that your splitter is rated to at least 750MHz.

Are you using multiple splitters?

If so, try to get the modem on the first 2:1 splitter.

If you have a 3:1 splitter, make sure you put the modem on one of the 2 splits that have a lower db loss (the db loss for each leg of the splitter will be printed on the splitter itself).

In general, it's best to split the cable only once before it hits the cable modem.

Also, possibly try replacing the splitter, maybe replace some of the cabling, tighten all your connectors, etc and then re-check your levels.

If all that doesn't get you into a good range, it might be time for a service call.
