When you're dealing with network connectivity issues, especially on mobile devices, a quick and effective trick is to use airplane mode to refresh your IP address. Many users don't realize that toggling airplane mode isn't just about disconnecting from calls and Wi-Fi—it's also a powerful way to reset your device's network stack.

When you turn on airplane mode, your device shuts down all wireless communications, including cellular data, Wi-Fi, and Bluetooth. As a result, the OS drops all active network leases and wipes temporary routing data.

When you turn airplane mode off again, your device reconnects to the network and requests a fresh IP address from the router or cellular provider. This quick toggle often fixes sluggish connections, dropped signals, or apps stuck loading because of outdated DNS or IP data.

It's especially useful when you're on public Wi-Fi networks that assign IP addresses dynamically or when your home router has a limited pool of available addresses. In crowded networks with limited DHCP pools, this reset can free up a usable address.

Unlike restarting your entire device, which can take time and close open apps, using airplane mode is fast and doesn't interrupt your workflow. Switch it on for a brief 10–15 second window, then flip it back off.

You'll likely see your connection reestablish and your internet speed improve almost instantly. Expect a near-instant return of stable connectivity and improved performance.

This method works on smartphones, https://hackmd.io tablets, and even some laptops with cellular modems. Applicable across smartphones, tablets, and any device with built-in mobile broadband.

It's not a fix for every network problem, but for common glitches related to IP conflicts or temporary routing errors, it's one of the most reliable quick fixes available. For DHCP issues, address conflicts, or transient routing bugs, this is the go-to solution among tech-savvy users.
