With the modem connected directly to the incoming line, here are the signal levels:
| Downstream Frequency | 837.000 MHz |
| Downstream SNR | 37.9 dB |
| Downstream Power Level | 0.7 dBmV |
| Upstream Frequency | 383.000 MHz |
| Upstream Power Level | 41.7 dB |
My modem is directly connected to the PC via ethernet. Here is a tracert to www.cox.net:
