Sluggish Wi-Fi may not be a permanent fixture in our lives, but when it happens, it can get on our nerves. Blaming your ISP-provided router or the plan speed is natural, but you should check your router’s settings first. Most people never think about modifying their router’s settings, but they are one of the quickest and simplest ways to optimize Wi-Fi performance. The default settings are rarely ideal, and once you see the difference a few tweaks can make, you’ll regret not doing so earlier. Whether it’s the wireless channels you’re connected to, your router’s QoS settings, or the firmware itself, changing these settings is highly recommended. Some of them may require you to replace your ISP’s router, but it’s worth it.
