智能手机几乎不能连接到互联网(Internet)有什么用？
有很多因素会导致您在Android 设备上的(Android device)WiFi 强度(WiFi strength)减弱。但现在还没有必要放弃。您可以增强您的WiFi 信号(WiFi signal)，使您的Android 设备(Android device)的互联网连接(Internet connection)更加稳定。
家庭用户
您(Are)的家庭WiFi有问题吗？您可以尝试以下几件事。您应该做的第一件事是查看路由器的频率和频道(frequency and channel)。
频率和频道
较旧的WiFi路由器在一个频段(frequency band)上运行- 2.4 GHz。如果您和您的邻居共享相同的频率，信号将会交叉，从而导致WiFi 连接(WiFi connection)较弱。
如果您的路由器作为双频销售，它支持 5 GHz(GHz frequency)频段。切换到 5 GHz可能会提高您的WiFi 强度(WiFi strength)。这个特定的频率人口较少，支持更多的频道。但是，它确实有更短的范围。
选择不同的频道
每个频率内都有较小的频带。这些被称为通道。2.4 GHz 频率(GHz frequency)平均有 11 个通道，而 5 GHz有 45 个通道。
理想情况下，您希望在没有其他人在的频道上。您可以使用免费的 Wifi 扫描仪软件(free Wifi scanner software)来检测您周围其他网络正在使用的频道。
对于使用 2.4 GHz的用户来说，这可能很困难，因为可供选择的选项较少。某些路由器具有自动为您选择理想频道的功能。但是您可以手动选择一个频道并无限期地停留在那里。
然而，使用 5 GHz的人有很多频道可供选择。在这个频率上撞到别人的可能性真的很小。
如何改变你的频率和频道(Your Frequency & Channel)
- 使用膝上型电脑或台式电脑(laptop or desktop computer)，连接到您的无线网络(wireless network)。
- 打开网络浏览器并输入(web browser and type)路由器的IP 地址(IP address)。
注意：(Note:)如果您不知道自己的IP 地址(IP address)，请打开命令提示符(Command Prompt)并输入IPCONFIG。您的 IP 地址将显示在Default Gateway下。另外，请阅读我们关于如何找到您的WiFi 接入(WiFi access)点 IP 的帖子。
- 填写(Fill)您的登录详细信息以输入路由器的设置。
- 路由器(Router)设置因品牌而异。但是您应该找到一个选项来更改频率（除非不支持 5 GHz(GHz isn)）和频道。
一些高级路由器将具有您可以下载的应用程序以远程访问这些设置。
选择频道
有这么多渠道，您如何选择使用哪一个？一种方法是使用Windows PC 并使用(Windows PC and use) 命令提示符(Command Prompt)或PowerShell。
- 打开两个程序之一并输入NETSH WLAN SHOW NETWORKS MODE=BSSID
此命令将向您显示所有广播网络、它们的SSID(SSIDs)以及它们正在使用的频道。
- 选择人口最少的频道。在上面的示例中，您可以选择 1 到 6 之间的频道，它不应干扰您邻居的信号。
您还可以下载Google Play上提供的众多Android 应用程序(Android apps)之一，例如WiFi Analyzer，以帮助分析您所在地区的WiFi信号强度。
购买 WiFi 中继器
WiFi 中继器(WiFi repeater)——顾名思义——重复WiFi 信号(WiFi signal)以扩展其范围。如果您住在大房子里，使用中继器可以将WiFi 信号(WiFi signal)增强到足以到达您的Android 手机(Android phone)的程度。
更新您的 WiFi 路由器密码
如果您尚未更新路由器的密码，则应立即更新。陌生人可能正在窃取您的WiFi 连接(WiFi connection)，导致您的互联网速度(Internet speed)下降。
进入您的WiFi设置页面并查找(page and look)可让您更新SSID 和密码(SSID and password)的部分。
相应地更新您的SSID 和密码(SSID and password)。请务必使用最新的网络加密技术(network encryption technology)WPA2。
在家外连接
您是否(Are)在家外使用WiFi时遇到问题？不幸的是，您的选择是有限的。这里有几个解决方法。
更新安卓和固件
您应该做的第一件事是确保Android 操作系统(Android OS)正在为您的设备运行最新版本。此外，请确保更新Android 手机(Android phone)上的浏览器应用程序(browser app)。Google会不断发布Chrome的新更新，它可以解决您的问题。
此外，根据您拥有的Android 手机(Android phone)，检查以确保您的设备没有任何可用的固件更新。如果是这样，请升级到最新固件。
取下你的手机壳
保护壳非常适合保护您的手机，但它们有时也会干扰Android 智能手机(Android smartphone)中的天线。如果您有坚固的外壳或带有某种金属的外壳，您的信号可能会下降。尝试在没有外壳的情况下使用设备，然后检查您的速度。
使用 Signal Booster 应用程序
由于Android拥有比 iOS 更开放的生态系统，您可以下载WiFi 加速器或 Signal Booster 应用程序(WiFi booster or Signal Booster app)来加速WiFi或 3G/4G/LTE。
确保(Make sure)下载评分超过 4 星且下载量超过 100K+ 的应用程序。
其他简单的措施
跳过不良连接(Skip Poor Connections)–避免(Avoid)WiFi 强度(WiFi strength)较差的网络。离路由器越远，信号越差。
停止移动(Stop Moving)——如果你在走路，你会从一个热点跳到另一个热点。这会干扰您的连接。留在原地，直到您完成在线浏览。
Remove/Avoid Obstacles ——如果有墙挡住，请绕过它。WiFi信号很难对抗建筑物。墙壁(Walls)、门和其他障碍物会降低WiFi 强度(WiFi strength)。
How To Boost The WiFi Signal On Android For Faster Internet
What use is a smartphone that can barely stay connected tо the Internet?
There are a lot of factors in play that can cause your WiFi strength on an Android device to weaken. But there’s no need to give up just yet. You can boost your WiFi signal to make your Android device’s Internet connection a more stable one.
Home Users
Are you having trouble with your home WiFi? Here are a couple of things you can try. The first thing you should do is to look at your router’s frequency and channel.
Frequency & Channels
Older WiFi routers operate on one frequency band – 2.4 GHz. If you and your neighbors share the same frequency, signals will get crossed resulting in a weaker WiFi connection.
If your router is marketed as dual-band, it supports the 5 GHz frequency band. Switching to 5 GHz might improve your WiFi strength. This particular frequency is less populated and supports more channels. It does, however, have a shorter range.
Pick a Different Channel
Each frequency has smaller bands within it. These are called channels. The 2.4 GHz frequency has 11 channels on average, while 5 GHz has 45 channels.
Ideally, you want to be on a channel that nobody else is on. You can use free Wifi scanner software to detect the channels other networks are using around you.
This can be tough for those using 2.4 GHz since there are fewer options to choose from. Some routers have a feature that automatically selects the ideal channel for you. But you can select one channel manually and stay there indefinitely.
People on 5 GHz however have plenty of channels to pick from. There’s really a small chance of bumping into someone else while on this frequency.
How to Change Your Frequency & Channel
- Using a laptop or desktop computer, connect to your wireless network.
- Open a web browser and type in the IP address of your router.
Note: If you don’t know your IP address, open Command Prompt and type IPCONFIG. Your IP address will show under Default Gateway. Also, read our post on how to find your WiFi access point IP.
- Fill in your login details to enter your router’s settings.
- Router settings vary by brand. But you should find an option to change both frequency (unless 5 GHz isn’t supported) and channel.
Some premium routers will have apps you can download to remotely access these settings.
Choosing a Channel
With so many channels, how do you choose which one to use? One way is to use a Windows PC and use Command Prompt or PowerShell.
- Open one of the two programs and type NETSH WLAN SHOW NETWORKS MODE=BSSID
This command will show you all the broadcasting networks, their SSIDs, and what channel they’re using.
- Select a channel that’s least populated. In the example above, you can select a channel between 1 and 6 and it shouldn’t interfere with your neighbor’s signals.
You can also download one of many Android apps available on Google Play like WiFi Analyzer to help analyze the WiFi signal strength in your area.
Buy a WiFi Repeater
A WiFi repeater – as its name implies – repeats the WiFi signal to extend its range. If you’re living in a big house, using a repeater can boost the WiFi signal hard enough to reach your Android phone.
Update Your WiFi Router Password
If you haven’t updated your router’s password, you should do so right away. Strangers could be stealing your WiFi connection, causing your Internet speed to drop.
Enter your WiFi settings page and look for the section that lets you update your SSID and password.
Update your SSID and password accordingly. Be sure to use WPA2, the latest in network encryption technology.
Connecting Outside Your Home
Are you having trouble with WiFi outside your home? Unfortunately, your options are limited. Here are a couple of workarounds.
Update Android and Firmware
The first thing you should do is to make sure the Android OS is running the latest version for your device. Also, make sure you update the browser app on your Android phone. Google is constantly releasing new updates to Chrome and it could fix your issue.
Also, depending on what Android phone you have, check to make sure there aren’t any firmware updates available for your device. If so, upgrade to the latest firmware.
Remove Your Phone Case
Cases are great for protecting your phone, but they can also sometimes interfere with the antenna in your Android smartphone. If you have a rugged case or a case with some sort of metal in it, your signal could be getting degraded. Try using the device without the case and then checking your speed.
Use a Signal Booster App
Since Android has a more open ecosystem than iOS, you can download a WiFi booster or Signal Booster app to speed up WiFi or 3G/4G/LTE.
Make sure to download an app that has a rating over 4 stars and 100K+ downloads.
Other Simple Measures
Skip Poor Connections – Avoid networks with poor WiFi strength. The further you are away from the router, the poorer the signal will be.
Stop Moving – You’ll bounce from one hotspot to another if you’re walking. This will interfere with your connection. Stay in place until you’re done browsing online.
Remove/Avoid Obstacles – If a wall is in the way, move around it. WiFi signals have a hard time going up against structures. Walls, doors, and other obstacles will reduce WiFi strength.
