What should my modem SNR be?

SNR is best over 30, (the higher the better, might work well with as low as 25 at times). Anything less than 25 will cause dropped connections, packet loss, slow transfers, etc.

What is RX SNR?

RX SNR refers to the receive signal to noise ratio. This represents the quality of the received signal. Normally the wanted signal will stick up some 6 to 15 dB above the noise floor.

How do I test my cable modem signal?

On almost all the Cable Modems or Cable Modem Routers, you can find your signal level by logging into the modem diagnostic GUI page via http://192.168.100.1 and username/password (unless you have changed credentials on the device, default credentials should be located on label on the device bottom or side).

What is Tx and Rx in WiFi?

Tx/Rx rate – displays the transmit/receive data rates (in Mbps). Tx data – displays the amount of transmitted data. Rx data – displays the amount of received data.

How do you fix SNR problems?

Fixing SNR Issues

1. Remove Extra WiFi networks. This is especially true if this is a business environment.
2. Check for “Noisy” devices. Take a look at the devices around the WiFi router.
3. Turn off unneeded signals. Some routers support multiple bands in the 2.4 GHz and 5 GHz range.

How can you tell if your modem is going bad?

However, if your modem is bad or is on the way to going bad, here is what you can expect:

1. The modem won’t turn on.
2. You can’t connect to the internet at all.
3. Internet connection drops in and out randomly.
4. Internet speed is inconsistent or is consistently slower than it used to be.

What is the best TX power in WiFi?

By default almost all WiFi access points transmit at full power (100mW on 2.4GHz). This gives maximum coverage and users see a good signal (“full bars”).

What is TX level and RX level in modem?

Tx and Rx Levels. The Tx level is the power in decibels per milliwatt (dBm) at which a modem transmits its signal. The Rx level is the power in dBm of the received signal. The server modems normally transmit at -13 dBm by default.

What Snr should I set my modem to?

If you hit 58 the modem will likely drop the connection and resync. SNR is best over 30, (the higher the better, might work well with as low as 25 at times). Anything less than 25 will cause dropped connections, packet loss, slow transfers, etc. This is true for both the “Downstream SNR” and the “Upstream SNR”, which may be different values.

What is the signal-to-noise ratio (SNR) of the server modem?

The server modems normally transmit at -13 dBm by default. Ideally, the Rx level should be in the range of -18 to -25 dBm. If the Rx level is under -25 dBm, the Signal-to-Noise Ratio (SNR) is likely to decrease, meaning that the speed also decreases.

Can I use my modem as a signal checker?

You’ll also be able to use the modem itself as a handy signal checker. If you, for example, have your cable modem plugged into a coax jack in your home office and you’re having connection problems, you could unplug the modem and plug it directly into the coax line coming into your home from the street.
