How to Determine if Your Wi-Fi Router Needs Replacement

Identify the signs of an aging router. Learn how to check your hardware standards and connectivity performance to determine if an upgrade is required.

1. Verify the Wi-Fi standard. Log into your router's web interface by entering its IP address—typically 192.168.1.1 or 192.168.0.1—into your browser. Look for the Wireless or Network settings page. If your hardware is restricted to 802.11n (Wi-Fi 4) or earlier, it is functionally obsolete and cannot handle modern high-speed traffic.
2. Perform a speed test against your plan. Run a speed test using a wired connection directly to the router to establish a baseline. Then, run the same test over Wi-Fi while standing in the same room. If your wired speed hits your ISP's limit but your Wi-Fi speed is significantly lower, the router's internal processor is failing to keep up with wireless encryption demands.
3. Check for manufacturer security updates. Search the manufacturer's support website for your specific model number. If the firmware release history has not been updated in over two years, your device is likely missing critical security patches. Replace any device that no longer receives manufacturer firmware support.
4. Evaluate connection stability. Observe the frequency of device disconnections. If your devices require a manual power cycle of the router more than once a month to restore internet access, the internal hardware, specifically the capacitors, is likely degrading. Frequent overheating and spontaneous reboots are definitive hardware failure signals.
5. Review device capacity. Compare your current router's device limit to the number of connected smart home devices in your network. Older routers struggle with modern device density, often resulting in packet loss and latency. If your router was purchased when you had fewer than ten devices, it is insufficient for current standards.
