Please also post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.
There's no way to tell just from that. We also have no idea what's been going on in your network, or what you have personally done to troubleshoot.
Nickpsycb, if you can post the signal levels requested here, that would be great. Also, are you using a router? Are you hardwired into your modem?
