Routers wear out from heat stress.
The heat that comes from the router working to connect all of your many devices can damage wires and components inside.
They have vents that allow the heat to escape.
If those vents are clogged with dust, the heat doesn’t escape.
How long do routers last?
I scoured through some online forums to read up on some experts’ opinions and from what I could collate, a wireless router typically lasts from two to five years. Since most models on the market would cost you anywhere from $100 to $200, it doesn’t seem like a bad deal.
How often should you replace your wireless router?
Generally, we recommend you upgrade to a new router every three to four years.
Do routers fail over time?
Yes. In general, routers can and do fail. The primary cause of failure for consumer grade equipment is heat stress. Long-term exposure to heat causes various components to degrade/fail and manifests itself as “intermittent” problems.
How do I know if my router is working properly?
To test if your router is working, try to ping one computer using another computer in the same network. You should be able to do this if the router is working properly. Your computer’s firewall must be disabled as well. To learn more on how to check the computer’s connectivity with the router, click here.
Do I need to upgrade my modem?
If it is, you’re good to go and you don’t need to upgrade. If your modem isn’t a DOCSIS 3.0 modem, it’s time to go shopping. If you still have an old DOCSIS 2.0 modem and there’s a firmware upgrade for it, you may be able to extend its life a bit and even see a speed boost in the process.
Is it better to have a separate modem and router?
Getting a separate router and modem gives you a lot of flexibility because if you want to upgrade your home network to have faster speed or more features, you just need to replace the router. What’s more, most routers on the market have more settings and features than the router part of a combo device.
