How often should you replace your Wi-Fi router? Expert advice

The Wi-Fi router is the backbone of your home internet — but it doesn’t last forever. IT expert Nikita Sheshin, product manager at Dom.ru, explains why and how often you should upgrade your router. According to him, routers should be replaced every 3 to 5 years due to hardware wear and the emergence of new Wi-Fi standards.

Why Do Routers Need Replacing?

1. Hardware Wear and Tear
   Routers operate 24/7, which gradually degrades their components. Over time:

• Performance decreases
• The casing overheats
• Issues arise, like reduced speed or sudden disconnections

2. New Wi-Fi Standards
   Every few years, new Wi-Fi protocols are introduced, offering better speed, stability, and security:

• Wi-Fi 6 (802.11ax): Supports 50–80 devices simultaneously — 4 to 5 times more than Wi-Fi 4 or 5 (802.11n/ac, which handle 10–15 devices)
• Wi-Fi 7 (802.11be): Gaining traction in 2025, offering speeds up to 46 Gbps and ultra-low latency

Older routers can't support these newer standards, limiting your network's potential.

Signs It’s Time to Replace Your Router

Sheshin identifies several warning signs that indicate your router needs replacing or repair:

1. Unstable Connection

• Devices disconnect from Wi-Fi for no reason
• Difficulty reconnecting
• Internet lags or slow speeds despite a fast plan from your provider

2. Overheating

• A noticeably hot router suggests worn-out internal components
• Overheating combined with connectivity issues is a red flag that failure may be imminent

3. Insufficient Capacity

• Older routers (Wi-Fi 4/5) struggle with the load from modern households
• If you have 20–30 smart devices (phones, laptops, smart speakers), your router might be overwhelmed

How to Choose a New Router

When shopping for a new router, consider:

• Wi-Fi Standard: Choose models with Wi-Fi 6 or Wi-Fi 7 for speed and future-proofing
• Number of Devices: Large families or smart homes need routers that can handle 50+ connections
• Frequency Bands: Dual-band models (2.4 GHz + 5 GHz) offer a good balance between range and speed
• Security: Look for WPA3 support to better protect against hacking
• Cooling: Routers with passive cooling or ventilation are less prone to overheating

Recommended 2025 Models:

• TP-Link Archer AX53 (~$80): Wi-Fi 6, supports up to 50 devices, speeds up to 3000 Mbps
• Asus RT-AX86U (~$200): Wi-Fi 6, gamer-friendly, supports up to 80 devices
• Netgear Nighthawk RAXE500 (~$400): Wi-Fi 6E/7, ideal for large homes

What to Do if Your Router Is Outdated

1. Check Its Condition

• Reboot the router and update its firmware (Settings → Software Update)
• Check how hot it gets after a few hours of use

2. Optimize Your Network

• Place the router in the center of your home, away from walls and electronics
• Use 5 GHz for speed, 4 GHz for longer range

3. Consider Repairs

• If it overheats, take it to a service center for diagnostics
• Replacing capacitors might extend its life, but this is rarely worth it for routers over 5 years old

4. Plan an Upgrade

• If your router lacks Wi-Fi 6 and can’t handle modern traffic, upgrading will significantly improve your connection

Conclusion

You should replace your Wi-Fi router every 3–5 years to avoid issues like overheating, connection drops, and slow speeds. New standards like Wi-Fi 6 and 7 offer more connections, faster speeds, and improved security. If your current router overheats, disconnects devices, or can’t handle your household’s needs — it’s time for an upgrade. Choose a router with Wi-Fi 6 or 7 support to ensure your network is ready for the demands of 2025 and beyond.
