Once a week we round up some of the great reader questi*** we get in the Ask HTG inbox and share the answers with everyone. This week we’re looking at checking your Wi-Fi signal strength from your phone, syncing iTunes to Android devices, and how to back up the Windows Home Server.

我如何能轻松地从android**中检查wi-fi信号强度？

Dear How-To Geek,

I followed your guide to extending your Wi-Fi network with a mesh of Tomato routers. Everything is working great but what I’m really curious about is the change in signal strength around my house. Is there an easy way to use my Android phone like a mobile signal reader? I have a rough idea how strong/weak the signal was before I turned extra routers on but I’d prefer to not lug my laptop around to every corner of the house again.

Sincerely,

Wi-Fi Curious

亲爱的Wi-Fi：，

尽管我们没有在你关注的番茄指南中提到它，但在我们启动新路由器之后，我们使用Android**进行了一些快速而肮脏的信号测试。我们最喜欢的应用程序之一是来自Amped Wireless的Wi-Fi分析工具，它结合了免费的啤酒价格和易于阅读的用户界面。它包括一个Wi-Fi扫描仪，帮助您检查通道干扰，并提供了一个非常容易阅读的信号图表。此外，您还可以将自动刷新时间设置为仅几秒钟，这样您就可以在家中慢慢漫步，而扫描仪每X秒钟自动刷新并显示一次信号强度。

现在，如果你改变主意，拿出笔记本电脑（你觉得雄心勃勃），你实际上可以使用你的房子和热图绘制一个你的房子/财产的信号强度热图。我们已经有一段时间热图上我们只是为了好玩极客信誉周末项目清单了。

如何将我的音乐从itunes同步到android？

Dear How-To Geek,

I know using iTunes and Android seems like a curious combination but my girlfriend loves the crap out of her iPod and she’s got an iPhone (which she had long before I had a **art phone) so this means all our music is organized in iTunes. Rather than try to break out of iTunes, how can I just embrace it and use it to sync music to my Android phone?

Sincerely,

iTunes In Love

亲爱的iTunes，

你不是唯一一个和iTunes/Android有这种关系的人。我们建议您查看我们的指南，使用Salling Media Sync在iTunes和Android设备之间同步音乐。我们也建议你去看看那本指南上的推荐信。尽管我们喜欢使用Salling Media Sync，但是在评论中有很多强有力的建议，比如doubleTwist，如果你感兴趣的话，它可以做Wi-Fi同步。

如何备份windows home server？

Dear How-To Geek,

I’ve run into a sort of “who will watch the watchmen?” moment with my home server. I’m running Windows Home Server, everything is great, but I now need some way to take the critical information on the Home Server and back it up for offsite ultra-safe storage. How should I approach this who-will-backup-the-backup problem?

Sincerely,

Home Server Tweaking

尊敬的家庭服务器：，

您首先需要一个大小合适的外部USB/eSATA驱动器。您可能不想备份整个Windows Home Server，只想导入内容（即，您不需要或不想备份所有服务器备份和还原点，只想备份您的文档、视频、家庭照片、，等）将外部驱动器连接到Windows Home Server，然后点击此处的指南查看如何将USB驱动器设置为易于删除的备份工具。
