If I remember correctly the imput level should be 3.5dB +/- 3dB.

actually for DOCSIS modems the receive levels are good between -11 and +11 dB, while transmit should be between 34 and 54 dB
that's my modem currently. the receive and transmit levels out of whack will generally cause slow or intermittent connections, while the downstream and upstream will cause your packetloss if they're too low (below 25 dB)
if receive or transmit are out of whack, those levels will turn red and if a TSR sees that when you call it it will usually trigger a service call right there. buildings with older cable lines can also suffer from static, and if you have connection problems you can try unplugging the coax cable from the back of the modem and grounding it against something (touching metal) which often helps clear up issues temporarily
