Fixing High Latency Issues with RTL8153B-VB-CG USB Network Adapters

Fixing High Latency Issues with RTL8153B-VB-CG USB Network Adapters

Introduction: High latency issues with USB network adapters like the RTL8153B-VB-CG can significantly affect the overall network performance. These delays can result in slow browsing, lagging online games, and interruptions in streaming. In this article, we’ll identify potential causes of high latency in these adapters, discuss the factors that contribute to this problem, and provide simple, step-by-step solutions for fixing the issue.

Understanding the Causes of High Latency:

High latency in network adapters like the RTL8153B-VB-CG can be caused by several factors. Let's break them down:

Driver Issues: Outdated or incompatible Drivers can cause poor network performance, including high latency.

USB Port Configuration: The performance of USB network adapters is closely related to the USB port type and configuration. If the adapter is connected to a slower USB 2.0 port instead of a faster USB 3.0/3.1 port, this can lead to significant latency.

Interference or Congestion: If there are multiple devices using the same USB bus or network, this can cause congestion, leading to high latency.

Network Configuration: Incorrect network settings or improper configurations in the operating system can also contribute to high latency.

Power Management Settings: Power-saving settings can impact the performance of USB network adapters. These settings might lead to the adapter entering low-power modes, which can increase latency.

Faulty or Low-Quality Cable: If the USB cable connecting the RTL8153B-VB-CG adapter is of poor quality or damaged, it can also result in high latency.

Step-by-Step Guide to Fixing High Latency:

Now, let's walk through the solutions to fix high latency issues step by step.

Step 1: Update or Reinstall the Network Adapter Drivers

Open Device Manager by right-clicking the Windows start menu and selecting "Device Manager."

Expand the "Network Adapters" section and locate your RTL8153B-VB-CG adapter.

Right-click on it and select Update Driver.

Choose Search automatically for updated driver software. Let Windows search for any updates and install them if available.

Alternatively, visit the official manufacturer's website and download the latest driver for the RTL8153B-VB-CG adapter. Follow the installation instructions on the website.

If updating doesn’t help, you can try uninstalling and reinstalling the drivers:

Right-click on the adapter in Device Manager and select Uninstall device. After uninstalling, restart your computer, and Windows should reinstall the driver automatically. Step 2: Ensure the Adapter Is Connected to a USB 3.0 or 3.1 Port

The RTL8153B-VB-CG USB network adapter performs best when connected to a USB 3.0 or 3.1 port. To check the port:

Physically examine the USB port: USB 3.0/3.1 ports are usually marked with a blue color or have the “SS” (SuperSpeed) symbol next to them. Move the adapter to a different port if it’s currently plugged into a USB 2.0 port. This can help improve the data transfer rate and reduce latency. Step 3: Disable USB Selective Suspend Power Setting

Windows has a power-saving feature called "USB Selective Suspend" that might reduce the power to your USB device when it's not in active use. This can cause latency or connection issues. To disable it:

Open Control Panel and go to Power Options. Click on Change plan settings next to your selected power plan. Click on Change advanced power settings. Scroll down and expand USB settings. Set USB selective suspend setting to Disabled. Click Apply and OK to save the settings. Step 4: Check for Network Configuration Issues

Sometimes, high latency can be caused by network configuration issues in your operating system. Here's what you can do:

Reset TCP/IP Stack: Open the Command Prompt as Administrator. Type the command netsh int ip reset and press Enter. Restart your computer. Disable Large Send Offload (LSO): Open Device Manager again and go to your network adapter. Right-click on it and select Properties. Go to the Advanced tab. Find and disable the option called Large Send Offload or TCP Checksum Offload. Apply the settings and restart your computer. Step 5: Test for Interference and Congestion

If multiple devices are connected to the same USB hub or there are many devices on your network, it might create congestion. To solve this:

Use a Different USB Hub: If you’re using a USB hub, try connecting the adapter directly to the computer to avoid potential interference. Check Network Traffic: Make sure there aren’t too many devices connected to your Wi-Fi or Ethernet network, which could be using up bandwidth. Step 6: Inspect and Replace the USB Cable Check if the USB cable connecting your RTL8153B-VB-CG is intact and of good quality. If you suspect the cable is damaged or of poor quality, replace it with a high-quality, shielded USB cable. Step 7: Restart Your Router and Modem

Sometimes, network latency issues might not be related to the USB adapter but to the network itself. Restarting your router and modem can help fix this:

Turn off your modem and router. Wait for about 30 seconds and then turn them back on. Once they are fully restarted, test your connection again to check for latency improvements. Step 8: Disable Background Applications and Check for Malware

Background applications or malware can consume network resources and cause latency:

Open Task Manager (Ctrl + Shift + Esc) and check for any programs that are consuming too much CPU or network resources. Close unnecessary applications. Run a full antivirus scan to ensure that malware isn't causing network issues.

Conclusion:

By following the steps above, you should be able to address and fix high latency issues with the RTL8153B-VB-CG USB network adapter. Start by updating your drivers and ensuring the adapter is plugged into a USB 3.0 or 3.1 port. If the problem persists, adjust power settings, check for network configuration issues, and troubleshoot for interference and faulty cables. With a bit of patience, you should be able to restore a stable and fast network connection.

If all else fails, consider reaching out to the manufacturer’s support team for further assistance.
