What should upstream power levels be?

Downstream and upstream power levels are important when determining if the cable line that is connected to your cable modem or modem router is receiving sufficient power. Good Downstream power levels are within -7 to +7 dBmV. Good Upstream power levels are within 38-48 dBmV.

Can cable signal be too strong for modem?

Many modems are even rated to +/- 15 dBmV. Too low means your signal is weak, and too high means the signal is strong – possibly too strong (and will need to be corrected with an attenuator or splitter). Upstream power levels should be between 40 – 50 dBmV.

What does it mean if one upstream channel is locked?

For a locked channel, downstream power level is outside the range of -15 to +15 dBmV. For a locked channel, downstream power level is more than three dB different from any other locked channel’s power level. For a single locked upstream channel: power level is outside the range of 35 to 57 dBmV.

What is upstream power?

Upstream Power refers to the line signal from the cable modem to transmit data back to the cable provider.

How many upstream bonded channels should I have?

Upstream power level limits depend on the number of upstream channels locked. For some networks, the power limits for 3 to 4 channels are 35 to 51 dBmV. Ideal levels are approximately 40 to 50 dBmV for single channels, 37 to 48 dBmV each for 2 to 4 channels.

What does upstream mean on a modem?

Upstream channels are also known as “upload speed.” This refers to the data that your computer sends out to the Internet. Your cable modem’s upload speed (or upstream channel) determines how much bandwidth of data your computer can send out to the Internet each second at full speed.

What are upstream channels?

How do you increase upstream power level?

By adding a splitter or choosing a higher loss leg can increase your Upstream signal level. It won’t cause the modem to falsely transmit more power. Doing a “reset” is normally an easy action.

Why is my upstream light orange?

UPSTREAM = AMBER means the UPSTREAM is NOT bonded. It is most likely happening since the US power is TOO HIGH.

How can I improve my SNR upstream?

To improve the upstream SNR margin on a DSL line, you’d either have to get the modem to transmit using more power, your you’d need to reduce the noise on the line (possibly by fixing faulty or degraded wiring). Unless your home’s telephone wiring is faulty, there’s not much you as a consumer can do to fix this.

What uses upstream bandwidth?

Live streaming applications such as YouTube Live require more upstream bandwidth than downstream due to the fact that the user is streaming live content upstream to the internet. In effect, applications adjust their bandwidth usage in response to changing network availability.

How can I lower the power level on my router?

How Can I Lower an Upstream Power Level? 1 Step 1. Connect your computer directly to the modem, using an Ethernet cable. Open a Web browser and type your router’s IP address in the address bar, 2 Step 2. 3 Step 3. 4 Checking Line Quality. 5 Step 1.

How do I check upstream power levels for a modem connection?

Upstream power levels that are too high will affect a modem connection’s consistency. Connect your computer directly to the modem, using an Ethernet cable. Click the “Status,” “Signal” or “Statistics” link. Locate the “Upstream” section and find the listed power level. Locate the first coax jack that enters your home.

How do I adjust the power level on my modem?

The names can vary by manufacturer and modem model. Locate the “Upstream” section and find the listed power level. Acceptable levels are usually between 30 dB and 55 dB. If the upstream power is above 55 dB, it needs to be lowered. Disconnect the modem’s power, wait five seconds and reconnect it.

What to do if the power is too high at first?

Reconnect the coax followed by the power. Test your signal levels again. If the upstream power is still too high at the first jack, there is nothing you can do on your end to resolve the problem. Contact your cable provider and advise them of the levels and steps you have taken to resolve.
