Gaming Desktop PC randomly loses wifi connection for several seconds at a time.

Hey, so I got a gaming desktop pc about a year and a half ago (December 2024), and as of a few months ago, it will randomly lose connection causing disconnection in online games, or freezing in place in said online games for several seconds until the pc obtains connection again. I’ve been looking for an answer for this problem ever since it started happening, and I’ve tried several solutions, none of which have worked, including getting a new, stronger, wifi provider, getting a node closer to my pc, someone even told me I should make it so that my pc “can’t disconnect from this network to save power” yet I didn’t even see the option to do that. What concerns me the most is this PC isn’t the first one to have an issue like this, I had an old pc that had similar issues to this but on a much more severe scale, the issue became so bad I ended up taking it to a PC place to see if they could figure out what the issue was, and when they couldn’t, I had to end up buying a new one. I don’t know if these problems are related or if im just very unlucky. If anyone has any advice on what to do, im willing to do just about anything at this point, thanks for reading. Also, I forgot to mention that my PC is the only device in the house to have these issues, no other device connected to the internet has ever had issues like this before.

    Hi Nate Carter,

    Each Wi-Fi chipset manufactures have their own considered bad chipset generations. They will give troubles include the problem you mentioned and hardly be fixed by software.

    Please provide me the motherboard model of your current PC, I will look up to see if it comes with one of those chipsets and if there's any workaround.

    If possible, please also give me the Wi-Fi model and modem model you're using.

    Thank you for your time.

    Random short Wi‑Fi drops on a single Windows 11 gaming PC are typically caused by power‑saving on the adapter, unstable drivers, or local interference. Use these targeted checks on the PC itself (since other devices are fine and the ISP/router has already been changed):

    1. Disable Wi‑Fi power saving in Windows This prevents Windows from briefly turning off the adapter, which can cause several‑second drops.
    2. Open Device Manager and expand Network adapters.
    3. Right‑click the Wi‑Fi adapter and choose Properties.
    4. Go to the Power Management tab.
    5. Clear Allow the computer to turn off this device to save power.

    If the issue is power‑saving related, this alone often stops the brief disconnects.

    1. Set wireless adapter to maximum performance This reduces aggressive power saving that can cause intermittent loss.
    2. Go to Control Panel > Hardware and Sound > Power Options.
    3. Select the active power plan and choose Change plan settings.
    4. Select Change advanced power settings.
    5. Expand Wireless Adapter Settings.
    6. Set Power Saving Mode to Maximum Performance.
    7. Update or reinstall the Wi‑Fi driver If the problem started “a few months ago,” a Windows or driver update may have destabilized the adapter.

    A. Try a clean reinstall of the adapter driver:

    1. In Device Manager, expand Network adapters and locate the Wi‑Fi adapter.
    2. Right‑click it and select Uninstall device.
    3. Check Attempt to remove the driver for this device.
    4. Select Uninstall.
    5. Select Start > Power > Restart.

    After restart, Windows will automatically look for and install the network adapter driver. Test gaming again. If Windows does not install a driver, install the latest one from the PC or adapter manufacturer (downloaded on another device and copied via USB if needed).

    1. Turn off any bandwidth/traffic‑shaping software If the PC has vendor network “suite” software (for example, gaming/“Killer” network utilities or similar), these can cause erratic behavior. One documented case of extremely slow or unstable speeds was fixed by uninstalling the vendor’s network management software from Apps & features. Remove any such tool and test again.
    2. General Wi‑Fi stability checks If drops persist, apply these general Wi‑Fi reliability steps:
    • Ensure the PC is close to the router or node and that there are minimal obstructions.
    • Check that the Wi‑Fi adapter is enabled and not being disabled/re‑enabled repeatedly in Device Manager.
    • Make sure Windows is fully updated: Start > Settings > Windows Update > Check for updates.
    • Restart the PC after changes.

    If, after disabling power saving, reinstalling the driver, and removing any vendor network software, the problem still occurs only on this PC, the Wi‑Fi adapter hardware in the desktop (card or USB dongle) may be marginal. In that case, testing with a different Wi‑Fi adapter (or a temporary Ethernet cable) is the most direct way to confirm.
