To disable it, head to Control Panel and open Power Options. Click Change plan settings next to your active power plan.

Now choose Change advanced power settings.

Expand the Wireless Adapter Settings, then Power Saving Mode, and set both On battery and Plugged in to Maximum Performance. Apply the changes, reconnect to your Wi-Fi, and you’ve removed one of the most common causes of random slowdowns and drops on Windows.

Why your laptop won’t switch to the nearest access point

Roaming aggressiveness controls how willing your Wi-Fi adapter is to let go of a weak access point and look for a better one. Set too conservatively, Windows will cling to a distant node long after the signal has degraded, which is why speeds can feel slow even when you’re closer to another access point. On a mesh network, this behavior is amplified. Instead of smoothly handing off between nodes, your laptop sticks with a poor connection until performance collapses, leading to stalls, dropped packets, and that familiar urge to toggle Wi-Fi just to force a reconnect.

To adjust it, open Device Manager, expand Network adapters, and double-click your Wi-Fi adapter. Switch to the Advanced tab and look for Roaming Aggressiveness or Roaming Sensitivity. The exact name may vary by driver, but the setting usually defaults to Medium-Low or Medium. For mesh networks, bumping it to Medium-High or High gives Windows permission to roam sooner and more decisively.

Apply the change and reconnect to your Wi-Fi. You don’t want the most aggressive option unless you’re constantly moving, but nudging this setting up a notch is often enough to eliminate sticky connections and improve your roaming.

Why random hardware addresses can do more harm than good

Random hardware addresses are a privacy feature meant for public Wi-Fi, and most modern Wi-Fi networks handle it well. Instead of using the same hardware ID every time you connect, Windows rotates it to make you tracking harder. That’s useful at airports and coffee shops. On a trusted home network, it might work against you.

Routers and mesh systems expect devices to be consistent. When your laptop keeps appearing as a new device, you can see slow reconnects, brief drops after sleep, or performance that feels unstable for no reason. This is especially worth trying if you use DHCP reservations, MAC filtering, or have an older router.

To turn it off for your home network, open Settings and go to Network & Internet > Wi-Fi. Select your connected network, then toggle Random hardware addresses to Off. If you don’t see it there, open Wi-Fi > Hardware properties and disable it from that screen instead.

This setting is per network, so you can keep it enabled for public Wi-Fi. Reconnect, and Windows will now use a consistent hardware address going forward.

Why outdated Wi-Fi drivers cause random slowdowns

Outdated Wi-Fi drivers are an easy thing to overlook , and yet they can be significant when it comes to network reliability. These drivers control everything from roaming behavior to power management and how your adapter negotiates speeds with the router. When they’re behind, you may feel slow throughput, inconsistent speeds, and odd compatibility issues that show up after a router or mesh firmware update. On modern networks, especially Wi-Fi 6 and mesh systems, driver updates often include real performance fixes, not just bug patches, and staying current can be the difference between a connection that feels flaky and one that keeps the movies streaming and the internet flowing.
