日復一日，你簡陋而努力工作的路由器將你的家庭網路連線在一起，並將其連線到更大的網際網路上。有可能把它累死嗎？

今天的問答環節是由SuperUser提供的，SuperUser是Stack Exchange的一個分支，它是一個由Q&a網站組成的社群驅動分組。

問題

超級使用者讀者JQAn在經歷了家庭路由器的麻煩之後，向社群提出了以下問題：

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 Can they become so outdated that they cause intermittent interrupti*** of service?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.

你能像舊車一樣把路由器磨壞嗎？讓我們看看社群的反應。

答案

超級使用者貢獻者John對此進行了分析，並提供了一些解決問題的見解：

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.

撰稿人克萊門諾爾指出，熱量很可能是罪魁禍首：

A (possibly) good example of the Second Law of Thermodynamics:

«Any transformation of a thermodynamic system is carried out with increase in entropy including overall entropy of the system and the external environment.»

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.

儘管Instructables上不乏操作指南，可以幫助您完成為路由器新增散熱片/風扇的過程，但除非您有心情使用DIY解決方案，而該解決方案可能無法最終解決您的問題，否則只需購買一臺新路由器通常會更容易。
