Extremely Slow Wi-Fi (Already Uninstalled Smartbyte)

Are you able to get better speeds if you directly connect with an ethernet cable?

Are there newer drivers for your model laptop?

I gave up on 5575 I have and got an external Ethernet USB adapter. I destroyed all

throughput on all other devices on the network.for zero gain!

Even if this had worked it would not be good for other users with 5g. Tried and found out: 

 WMM is required by 802.11n and 802.11ac for link speeds above 54 Mbps, so disabling it can affect your overall Internet speed. If your Internet speed is 20 Mbps or less, then you maybe could get away with disabling WMM, but WiFi is going to be terrible. You could also try playing around with Dynamic QoS, if supported by the router. Dynamic QoS works on top of WMM and may be able to re-prioritize your gaming traffic.

If you're experiencing extremely slow Wi-Fi on your Dell laptop, there could be various factors contributing to the issue. Here's a step-by-step guide to help you troubleshoot and potentially improve your Wi-Fi speed:

1. Check Other Devices:

   • Verify if other devices connected to the same Wi-Fi network are also experiencing slow speeds. This will help determine if the issue is with the laptop or the network itself.

2. Restart Router and Modem:

   • Unplug your Wi-Fi router and modem from power, wait for about 30 seconds, and then plug them back in. This can help refresh the network connection.

3. Positioning of the Laptop:

   • Ensure that your laptop is within a reasonable distance from the Wi-Fi router. Walls, obstacles, and distance can weaken the signal strength.

4. Interference:

   • Other electronic devices, such as cordless phones, microwave ovens, and neighboring Wi-Fi networks, can interfere with your signal. Keep your laptop away from such devices and select a Wi-Fi channel with less interference.

5. Update Wi-Fi Drivers:

   • Outdated or faulty Wi-Fi drivers can affect your connection speed. Update your laptop's Wi-Fi drivers through the Device Manager.

6. Check for Background Downloads or Updates:

   • Check if any background processes, updates, or downloads are consuming your network bandwidth. This can significantly affect your Wi-Fi speed.

7. Change Wi-Fi Channel:

   • If you're in an area with multiple Wi-Fi networks, changing the Wi-Fi channel can help avoid interference. Access your router settings and experiment with different channels.

8. Disable Power Saving for Wi-Fi:

   • Sometimes, power-saving settings can affect Wi-Fi performance. Go to "Control Panel" > "Power Options" > "Change plan settings" > "Change advanced power settings." Under "Wireless Adapter Settings," set "Power Saving Mode" to "Maximum Performance."

9. Check for Malware or Background Processes:

   • Malware or resource-intensive background processes can slow down your laptop and network. Run a full system scan using your preferred antivirus software and check for any unusual processes in the Task Manager.

10. QoS Settings:

    • If your router supports Quality of Service (QoS) settings, you can prioritize certain devices or applications to ensure smoother internet performance.

11. Reset Network Settings:

    • If you've exhausted other options, you can try resetting your network settings. Go to "Settings" > "Network & Internet" > "Status" > "Network reset." This will remove and reinstall all network adapters and settings.

12. Contact Dell Support:

    • If the issue persists despite trying these steps, consider reaching out to Dell's customer support for further assistance. They can provide specific guidance based on your laptop model and configuration.

Remember that Wi-Fi performance can be influenced by various factors, and the solution might require a combination of troubleshooting steps. If you're not comfortable with these steps, consider seeking help from a knowledgeable friend or a professional technician.
