日复一日，你简陋而努力工作的路由器将你的家庭网络连接在一起，并将其连接到更大的互联网上。有可能把它累死吗？

问题

超级用户读者JQAn在经历了家庭路由器的麻烦之后，向社区提出了以下问题：

I’ve been having problems with my internet connection over the past weeks (intermittent disconnecti***, slow transfers, etc.), and my provider keeps telling me that the problem is not on their end.

I have cable modem with a Wi-Fi router (this router was not provided by them).

The router is quite old (DIR-300), so I’m starting to wonder if it could be the issue and if I should replace it.

Is it possible that it is the cause? Can they become so outdated that they cause intermittent interrupti*** of service?

If I reset the modem and the router, they work fine for a few hours, but the problems starts again after a while.

你能像旧车一样把路由器磨坏吗？让我们看看社区的反应。

答案

Yes.

In general, routers can and do fail. The primary cause of failure for c***umer grade equipment is heat stress. Most c***umer grade hardware runs far too hot and have respectively poor air circulation compared to their ventilation needs.

Long-term exposure to heat causes various components to degrade/fail and manifests itself as “intermittent” problems. In general, c***umer grade hardware is not as robustly made as commercial or enterprise hardware. But all physical devices are subject to physical effects.

It’s not uncommon for c***umer grade devices to fail within a few years due to heat or vibration issues. Routers stuck near windows (argh! the sun!), placed on the floor (dust!), or jammed into a bookcase (no air flow) are especially prone to failures. Contrast that with commercial grade devices which are often still working for 10 or more years after their first deployment.

Most cable modems have either an Ethernet port or Wi-Fi ability. To isolate the cause of your network problems, you should c***ider bypassing your router and plugging your PC/laptop directly into the cable modem to see if whether or not you experience the same problems.

Of course, bypassing the router means you bypass the router’s firewall protection and NAT abilities so take due precauti*** on your computer.

This may be an overheating problem or the overheating is the symptom…

The easiest way to check if the router is Out of Service or near to this inevitable state, you may try with another one temporary (from a friend for example). If this solved the Internet connection problems, you have the answer.

尽管Instructables上不乏操作指南，可以帮助您完成为路由器添加散热片/风扇的过程，但除非您有心情使用DIY解决方案，而该解决方案可能无法最终解决您的问题，否则只需购买一台新路由器通常会更容易。
