改变或扩展您在自己家中设置的Wi-Fi网络的功能是一回事，但是当其他人执行了安装，并且出色地将路由器“隐藏”在一个谨慎、偏僻的位置时，您会怎么做？今天的超级用户问答有一些有用的建议，可以帮助失意的读者找到难以捉摸的路由器。

问题

超级用户读者西蒙斯想知道如何找到一个路由器，之前已经设置在一个“未知”的位置在房子里：

I want to install a WLAN repeater in my father’s holiday house that he rents out to other people. My father is not that well-versed when it comes to digital electronics and does not know where the router is, therefore I am unable to configure my repeater with the router.

Are there any tools that could help me find where the router is in his house? I know that there are tools that tell you which Ethernet cable is in use and where it points to, so I figured that there should also be tools that can help me find the router.

By tools, I do not necessarily mean just software, I am also thinking about hardware-based tools. I have tried going around the house using my mobile phone to search for the area with the best connection to the network, but have had no luck in finding the router.

Additional Information:

Due to the comments asking for more information about the router, it is a normal ADSL/VDSL Wi-Fi capable router distributed by the market leading ISP in my country (it is also WPS capable).

答案

超级用户贡献者gronostaj、Dotankohen和Xen2050都有我们的答案。首先，格罗诺斯塔吉：

If you have an Android mobile phone or tablet, you can use the Wi-Fi Analyzer app. It has a screen dedicated to detecting the proximity of access points.

Walk around the house and see where the signal is the strongest.

接着是多坦科亨的回答：

You are going to laugh, but I went through the same exact situation. I could not find my mother-in-law’s router since the cable company was the one resp***ible for installing it.

When my nephews came over, they wanted to access the Wi-Fi with their Samsung Tablet. I told them that the Wi-Fi code was on a sticker on the bottom of the router. They turned the whole house upside-down and found the router on a top shelf in the cupboard. I have no idea why it was placed there, but suspect it was for better reception. The wire running to it went through a wall, so it was obviously not an easy place to install. That technician really gave it his best.

So find some kids with a tablet and invite them over. They will definitely find the router if that is what stands between them and Facebook or other online activities.

Xen2050的最终答案是：

Barring an obvious wire leading to it, searching by Wi-Fi signal strength should be a good approach. The “walk around blindly with a strength meter” approach is not very helpful, so use an app that will map it for you like ekahau Heat Mapper.

It can make a map for you that should give you a better idea of which areas to concentrate your search in. It is for Windows and the How-To Geek website has a guide for using it. The guide says that it is “essentially the free version” of the multi-thousand-dollar Ekahau SiteSurvey software. The best part is that it may find the router for you.

• Once we finished walking the entire map, HeatMapper pinpointed the location of the two access points within our office with uncanny precision. Look at the red arrows on the map below:

There are some Android and iPhone apps that should be similar as well. Try searching for one that works on your device, perhaps Telstra Wi-Fi Maximiser (for Android). Here is a screenshot for it:

My First Ideas Were:

1. I would just follow the wiring in the house, starting from where it enters the house and checking wherever the main cable or telephone juncti*** are. You did not say if it was telephone/DSL, television (coax) cable, pure network cable, or fiber optic, but they all enter the house from somewhere (unless you have all underground utilities). They probably do not enter through the basement, or the “tube” would still come up from the ground somewhere outside the house.

If a technician installed the router and/or network cable recently (i.e. not originally built into the house), then try looking around the main television or telephone areas (high and low anywhere within reach). Check for mystery power cords plugged in around those areas and follow them.

2. Contact the Internet service provider and ask them where they installed it. Perhaps most of the houses in the area have a standard layout, or the installers always put them on the floor under television sets, or in attics or someplace unexpected. They just might have been diligent enough to make notes about where it is in the house.
