What are the best ways to improve my home Wi-Fi network's performance?

Improving your home Wi-Fi network's performance can be a bit of a challenge, but don't worry, I'm here to help. First, let's talk about the issues you're experiencing. Weak signal strength in certain areas and slow speeds when multiple devices are connected are common problems, especially in larger homes with multiple floors.

Upgrading your router or adding range extenders can definitely help, but before we dive into that, let's cover a few basics. Make sure your router is placed in a central location, as you've already tried, and that it's at least 5-7 feet off the ground to minimize interference from walls and floors. You can also try changing the Wi-Fi channel on your router to one that's less crowded - you can use tools like Wi-Fi Analyzer to help you find the best channel.

Now, about upgrading your router. If you're using an older router, it might be worth considering a newer model with better range and speeds. Look for a router that supports Wi-Fi 6 (also known as 802.11ax) and has a strong signal strength. Some popular options include the TP-Link Archer AX6000 and the Netgear Nighthawk AX8. Keep in mind that a new router can be a bit pricey, but it can make a big difference in your network's performance.

Range extenders can also be a good option, especially if you have areas in your home where the signal is weak. These devices can help extend the range of your Wi-Fi network, but keep in mind that they can also introduce some latency and reduce speeds. You can try using a Wi-Fi range extender like the Netgear EX2800 or the Linksys RE6500
