Your phone clings to the weak upstairs Wi-Fi, and your router has a setting to make it let go

Those with a mesh Wi-Fi system will know the universally annoying scenario of walking downstairs into your living room and sitting right next to a secondary mesh node or access point. You then open a video stream only for it to buffer endlessly on a single lagging bar of Wi-Fi. It's easy to blame your ISP, your router's range, or even the concrete walls of your home when, in reality, your router isn't failing to transmit. It's actually your smartphone that is stubbornly refusing to disconnect. It is trapped in a sticky client loop, holding on to a faint -82 dBm signal from the upstairs router rather than switching to the pristine -45 dBm node just a couple of feet away. Wi-Fi roaming decisions actually belong to the client device rather than the router, and smartphones can be notoriously stubborn when it comes to this setting. There is a range of standards you can enable and configure to forcibly kick sticky phones off weak signals and achieve seamless room-to-room handoffs. The sticky client problem lies in your phone And this can cause battery drain Cloudflare provides you with more information when compared to a standard speed test.Cloudflare provides you with more information when compared to a standard speed test. What are the mechanics behind the sticky client problem? Well, there is a fundamental design flaw in the 802.11 Wi-Fi specification. This decision to disconnect from one access point and search for another rests almost entirely on the smartphone's internal wireless card logic. This means that your smartphone can easily fall into threshold traps. Many mobile OSes, including iOS and Android, prioritize connection stability over speed. This means most phones won't even start scanning for a better access point until the current signal drops below a hard threshold, often -70 dBm, sometimes even as low as -75 dBm. Essentially, your connection has to be close to non-existent before your phone even starts hunting for an alternative. Alongside the poor connection itself, there are other penalties to staying connected to a weak signal. The first is airtime consumption, as the phone requires frequent packet retransmissions at low data rates. This means that your device can hog physical radio airtime. Alongside this, you might notice a bit more of a battery drain on your phone. This is because the Wi-Fi chip cranks up its transmission power to maximum to maintain a faint connection, which can drain the battery over time. Adjusting your router settings can make all the difference Force your phone off the distant access point By adjusting some of your router settings, you can force a disconnect between your phone and the distant access point. The first setting you might want to adjust is the minimum RSSI, which is the signal threshold kick. Setting a minimum RSSI limit, for example, -72 dBm inside your router or access point settings, is fundamental. This means when a phone signal degrades past that line, the router forcibly sends a de-authentication frame, forcing the phone to disconnect and rescan for the closest node. Setting up neighbor reports, otherwise known as the 802.11k protocol, can also help bridge the gap. It feeds your smartphone a list of nearby access points and their channel loads before the signal actually drops, which should, in turn, reduce the time it takes for your phone to find a better node. The 802.11v or BSS transition management setting also allows your router to actively suggest a better target AP to your phone when the signal quality degrades. And lastly is the 802.11r protocol, which enables fast BSS transitions. This is because this protocol eliminates the re-authentication overhead when moving between secure WPA2/WPA3 nodes, cutting handoff times and stalling wait times from higher (sometimes over 500 ping) all the way down to under 50 ping. This should prevent dropping VoIP. Monitor your network closely And fine-tune it to work for you There are other steps you can take to fine-tune your network and find that golden threshold in your home, too. Simply configuring the router as outlined above might not be enough to ensure your network feels stable throughout your home. The first step you might want to undergo is actually mapping your signal strength. You can use a free Wi-Fi analyzer app to measure actual signal levels in problem rooms by walking through your home with a wireless device. This will help you identify where you might have weak points in your home, so you can map your nodes correctly. Next is adjusting your access point's transmit power. You don't need all of your nodes to overlap, so by lowering your router's transmission power from high to medium, or sometimes even low, signals won't bleed across floors. This can encourage your devices to drop weak connections and connect to the best access points. Repair the problem directly You don't always need to buy more nodes When your phone is clinging to a faint signal, it's easy to blame your router, network, or even your internet service provider when in reality the problem might lie within your smartphone itself. Mobile operating systems are notoriously lazy about dropping bad Wi-Fi connections. By adjusting a few of your router's advanced wireless settings and setting a minimum RSSI threshold, you might be able to encourage your phone to drop those faint connections and actually use the nodes you've paid for in their prime positions.
