Resolve Issues with Data Transfer Rate

Issue

The data transfer rate you can achieve between your radio and host depends on the specifications and quality of your network connection. If you successfully connect and set up your radio using the Radio Setup wizard and pass the validation steps, you can still encounter issues with data transfer speeds.

For help resolving issues encountered with connecting your radio to your host during radio setup with the Radio Setup wizard, see Resolve Issues with Connecting Radio to Host. For help resolving errors encountered during the validation tests, see Resolve Issues with Radio Setup Validation.

Possible Solutions

Set the Gigabit Ethernet Adapter Driver Settings

If you are using a Windows^® system, you can manually configure the Ethernet adapter driver settings on your host computer to optimise your data transfer speed.

To verify that an appropriate Ethernet network adapter driver is installed and working properly, follow these steps:

1. Open Windows Device Manager and click Network adapters.

2. Under Network adapters, right-click the Gigabit Ethernet adapter entry dedicated to the network connection and click Properties in the context menu.

3. In the Adapter Properties dialog box, click the Driver tab to verify the driver.

In the Adapter Properties dialog box, click the Advanced tab. For the best performance, use the following settings for the jumbo packet and receive buffer values.

• Set the Jumbo Packet (or Jumbo Frame) value depending on your Ethernet connection.

  • If you have a 1 Gigabit NIC, set the value to 1500 bytes, which is the standard Ethernet frame size. If you cannot set the value to 1500, set it to the nearest valid value.

  • If you have a 10 Gigabit NIC, set the value to the maximum supported value, for example, 9014 bytes. Gigabit Ethernet controllers that support jumbo frames can transfer packet sizes larger than the standard Ethernet frame size.

• Set Receiver Buffers (or Receiver Descriptors) to the maximum supported value, for example, 2048. For some Ethernet controller drivers, the setting is grouped under Performance Options.

  Note

  If you are using a USB3/Ethernet adapter dongle and you cannot access this setting, you may not be able to achieve the required data transfer speed. Consider using a dedicated NIC or a different adapter dongle.

Optimize or Upgrade Your Network Connection

If you are using a 1 Gigabit NIC, consider upgrading it to a 10 Gigabit NIC.

If you are using a USB3/Ethernet adapter dongle:

• If you are also using a laptop, connecting to a power supply can improve data transfer speed.

• Consider trying a different model of adapter.

• Consider having an additional NIC installed on your computer that you can use to connect to the radio.
