  1. Slow Wi-Fi usually after Laptop sleeping


    I have a strange problem where the WiFi download rate falls from time to time most commonly after the laptop has gone into sleep mode

    But that may be a red herring!

    The Laptop is a Dell 7530 i9 8th Gen running Windows 10 Pro Build 19042

    The wifi properties are

    Slow Wi-Fi usually after Laptop sleeping 2199318b-62cb-45b1-b5dd-0cf2dd065051?upload=true.jpg

    Speedtest.net is reporting 14mbps down and 36.75mbps up


    If however I disconnect and reconnect the WiFi connection on the laptop, Speedtest.net then reports

    278mbps down and 71mbps up


    So all it takes is disconnect and reconnect to fix it until the next time. Even when the laptop is in slow mode I can connect other devices such as my iPhone or MacBook pro and they have the full speed.


    How would I go about diagnosing this - How do I find what is responsible - The WiFi is reporting a good link speed of 866/866 Mbps


    Many thanks, Jon

    :)

  2. Slow wi-fi

    My laptop, with Windows 10, runs extremely slow on Wi-fi - about 15 Mbps. The warranty dept at Costco is suggesting running Windows 10 back to the factory default. Do you think this will help? I'm thinking it must be a hardware issue, specifically the
    network card?

  3. Wi-Fi errors (Windows 10)

    I'm currently troubleshooting a HP laptop (HP G62-a10SQ to be more specific). The problem is that it doesn't want to connect to any Wi-Fi network. It leaves me with the generic error "Can't connect to this network." I've tried these steps so far

    • Restarting the computer
    • Flushing DNS
    • Releasing and renewing the ipconfig
    • Uninstalling the driver
    • Reinstalling the driver
    • Reseating the Wi-FI module
    • Checking Windows Update for any drivers
    • Updating the driver in Device Manager
    • Temporarily removing my Wi-Fi encryption
    • Trying to connect to a different Wi-Fi network outside of my network
    • Probably more troubleshooting steps I can't remember atm (I will edit the post if I remember anything)

    Trouble Changing Wi-Fi Password


    I've been following the following steps to change my Wi-Fi password for some time:

    1. Launch Control Panel.
    2. Click "Network and Internet."
    3. Click "Network and Sharing Center."
    4. Click "Wi-Fi...."
    5. Click "Wireless Properties."
    6. Click the Security tab.
    7. Check "Show characters."
    8. Enter the password in "Network security key."
    Those steps have been working just fine, but today I discovered a new wrinkle. If I change the password inside the router first, "Wi-Fi..." doesn't appear in step 4. This isn't much of a problem at home, because I can just change the password in Control Panel before I change it inside the router, but it would be a problem at a public hotspot, or something of that nature. I also tested Brink's instructions in "How to Connect To a Wireless Network in Windows 10," but they don't work for me either. How can I fix this?
