Step by step
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.
Note: Modern standards begin at 802.11ac (Wi-Fi 5) or higher.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.
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.
Note: An unpatched router is an open entry point for network intrusions.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.
Note: Ensure your router has adequate ventilation before concluding it is failing.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.
