3. In the Downstream Bonded Channels section, identify the Modulation and Power to find verify SNR levels are within the acceptable range for each downstream channel. Acceptable SNR Levels (dB): If QAM64, SNR should be 23.5 dB or greater. If QAM256 and DPL( -6 dBmV to 15 dBmV) SNR should be 30 dB or greater. If QAM256 and DPL(-15 dBmV to -6 dBmV) SNR should be 33 dB or greater.
ARRIS SB6183: Troubleshoot Internet Connection Information Question How do I troubleshoot Internet connection issues with my SB6183? If Internet connection issues with the SB6183 arise, troubleshooting may resolve the issue, or may provide insight as to what is causing the issue. This document provides helpful information for troubleshooting Internet connection issues with the SB6183. The following troubleshooting steps are to be followed in sequence: 1. Check the physical connection 2. Verify the LEDs 3. Power Reset 4. Factory Reset 5. Verify the cable signal Answe r NOTE: If the solutions provided in this document do not resolve the issue, please contact the cable operator for assistance. Check the physical connection 1. Verify that the SB6183 power cord is connected from the power port of the SB6183 to the power outlet. 2. Verify that the coaxial cable is connected from the cable port of the SB6183 to the cable outlet. 3. Verify that the Ethernet cable is connected from the Ethernet port on the SB6183 to the Ethernet port on the computer. Verify the LEDs With the proper setup, the Online LED should be solid green. If this is not the behavior that the SB6183 is displaying, please refer to this table for more information regarding LED behavior. Power Reset 1. Shutdown the computer. 2. Unplug the cable modem from the AC wall outlet and wait one minute. 3. Plug the cable modem into the wall outlet. 4. Wait until the Power, Receive, Send, and Online LEDs are solid. 5. Restart the computer. Factory Reset 1. Disconnect the coaxial cable. 2. Power cycle the unit by disconnecting the power cord for 10 seconds, then reconnect the power cord. 3. Launch a web browser, such as Internet Explorer, Firefox, or Safari. Enter http://192.168.100.1 into the address box. The Status page will appear. 4. Click the Configuration link on top. The Configuration page will appear. 5. Click the Restore Factory Defaults button (as shown below). 6. When asked, Do you want to proceed?, click the OK button. The modem will reset to it's factory state, and will go through the initialization process. 7. Connect the coaxial cable to the modem. NOTE: The initialization process may take 5 to 30 minutes. Verify the cable signal 1. Launch a web browser, such as Internet Explorer, Firefox, or Safari. Enter http://192.168.100.1 into the address box. The Status page will appear. 2. In the Downstream Bonded Channels section, verify Power levels are within the acceptable range of - 15 dBmV to + 15 dBmV for each downstream channel. 3. In the Downstream Bonded Channels section, identify the Modulation and Power to find verify SNR levels are within the acceptable range for each downstream channel. Acceptable SNR Levels (dB): If QAM64, SNR should be 23.5 dB or greater. If QAM256 and DPL( -6 dBmV to +15 dBmV) SNR should be 30 dB or greater. If QAM256 and DPL(-15 dBmV to -6 dBmV) SNR should be 33 dB or greater. 4. In the Upstream Bonded Channels section, identify the number of Channels, Type, Symbolic Rate to find verify Upstream Power levels are within the acceptable range for each upstream channel. Acceptable Upstream Power Levels (dBmV): Upstream Transmit Power Level Channel US Channel Type Symbol Rate Acceptable US Power Level TDMA 1280 Ksym/sec +61 dBmV to 45 dBmV Single ATDMA 2560 Ksym/sec +58 dBmV to 45 dBmV 5120 Ksym/sec +57 dBmV to 45 dBmV TDMA 1280 Ksym/sec +58 dBmV to 45 dBmV Two ATDMA 2560 Ksym/sec +55 dBmV to 45 dBmV 5120 Ksym/sec +54 dBmV to 45 dBmV TDMA 1280 Ksym/sec +55 dBmV to 45 dBmV 2560 Ksym/sec +52 dBmV to 45 dBmV Three or more ATDMA 5120 Ksym/sec +51 dBmV to 45 dBmV 5. Refresh the page at least twice to identify variations in SNR, Downstream Power, and Upstream Power. NOTE: If the either of the signal levels are outside of the acceptable range, power cycle or factory reset the modem. 6. Contact the cable provider to adjust the signal level to the acceptable level range.
