我已经使用Netgear 无线(Netgear wireless)路由器大约一年了，它一直很好，直到几周前突然我的无线连接不断下降，或者除非我重新启动路由器，否则我无法连接！(t connect)这是一种皇家的痛苦(royal pain)，但因为我很懒，我没有早点修复它！如果您遇到同样的情况，您可以采取以下措施来解决问题！
问题通常是由以下三件事之一引起的：无线网卡的驱动程序、路由器上的固件版本（基本上是路由器的驱动程序）或路由器上的设置。我发现除非您使用的是非常旧的无线路由器(wireless router)，否则罪魁祸首很可能是您的无线网卡的旧驱动程序。所以你必须更新无线网卡。我们如何做到这一点？
更新电脑驱动程序
首先，您需要访问您的计算机制造商的网站： (web site)Dell、HP、Toshiba等，然后访问他们的支持或驱动程序下载页面(support or driver downloads page)。在这里，我尝试获取最常见计算机的这些页面的直接链接：
戴尔 – http://www.dell.com/support/home/us/en/19/Products/
惠普 – http://www8.hp.com/us/en/drivers.html
东芝 - http://support.toshiba.com/drivers
索尼 – http://esupport.sony.com/perl/select-system.pl?DIRECTOR=DRIVER
联想 – http://support.lenovo.com/us/en/products?tabName=Downloads
选择您的系统或输入它并为您的无线网卡找到最新的驱动程序。通常有一个名为Networking的部分，您应该在下面看到一个驱动程序列表。其中一个应该有“无线”这个词。如果您有多个无线驱动程序(wireless driver)，那么您需要弄清楚您的计算机上安装了哪一个。
您可以通过同时按下Windows 键(Windows key)+暂停(Pause )按钮来确定无线网卡的型号。(model number)这将打开系统属性(System Properties)对话框。另一种方法是右键单击My Computer并选择Properties。在那里，单击高级系统设置(Advanced system settings)。
单击硬件(Hardware )选项卡，然后单击设备管理器( Device Manager)。
您将看到左侧带有加号的设备列表。单击名为“网络适配器(Network Adapters)”的那个，您的无线网卡将出现一个条目，如下所示：
现在从制造商网站的列表中下载该驱动程序。通常无线网卡被称为“Intel Pro Wirelss”或“Dell Wireless”等。将文件下载到桌面后，双击它并按照步骤进行安装。您可能需要重新启动计算机。
如果计算机上的驱动程序有问题，则断开的连接应该完全消失。如果没有，那么您可能必须尝试更新路由器固件(router firmware)。
更新路由器固件
更新路由器固件(router firmware)是一项不那么简单的任务，具体取决于您碰巧拥有的路由器品牌。(router brand)它们几乎都没有(Almost none)自动更新功能(update feature)。相反，您必须从他们的网站下载最新的固件，登录您的路由器，然后将其上传执行更新。
首先，您需要找出路由器的IP 地址(IP address)并使用(router and use)它通过浏览器登录。阅读我关于查找无线接入点(access point)IP 地址(IP address)的帖子。由于不同品牌的路由器固件(router firmware)更新方法差异很大，因此最好搜索您的路由器型号(router model number)+“固件更新”以查找具体说明。
路由器设置
可能导致连接断开的最后一个问题是路由器上的各种设置。最近，您拥有双频路由器，可让您在 2.4 和 5 GHz网络上进行广播。这些高级路由器通常与最新的小工具和计算机配合得很好，但在旧机器上，您有时会遇到问题。这是我会尝试的几件事：
1.如果您当前连接到 5 GHz(GHz one)网络，请连接到 2.4 GHz 网络(GHz network)。
2. 在路由器上，确保网络的通道设置设置为自动(Auto)。如果您出于某种原因选择了特定频道，请尝试其他频道。
3. 关闭额外的安全功能，如MAC 地址(MAC address)过滤、网络隔离和 Wi-Fi 保护设置(network isolation and Wi-Fi Protected Setup)。这些都没有真正提高安全性，最终导致更多麻烦。
4. 确保您的无线网络模式(wireless network mode)设置为混合(Mixed)。有时选择更高的模式可能会导致旧设备出现问题。
5. 如果您对路由器设置一无所知，请尝试按重置按钮(reset button)完全重置路由器。配置(Configure)无线安全并保留它。
希望(Hopefully one)这些解决方案之一将解决您的无线连接问题(connection problem)。如果您有不同的解决方案，请发表评论并告诉我们。享受！
Wireless Tips – Does Your Wireless Router Keep Disconnecting or Dropping the Connection?
I’ve hаd a Netgear wireless rоuter for aboυt a year now and it’s been pretty good untіl a couple of weeks back аll of sudden my wireleѕs connection kept dropping or I couldn’t connеct unless I restarted the router! It was a roуal pain, but because I’m lazy I didn’t get around to fixing it earlier! If you’re in the same situation, here’s what you cаn do to fix the problem!
The issue is usually caused by one of three things: the driver for your wireless card, the firmware version on your router (basically the driver for the router) or settings on your router. I have found that unless you’re using a really old wireless router, it’s more than likely an old driver for your wireless card that is the culprit. So you have to update the wireless card. How do we do that?
Update PC Driver
First, you’ll need to go to the web site for the manufacturer of your computer: Dell, HP, Toshiba, etc and go to their support or driver downloads page. Here I’ve tried to get the direct links to those pages for the most common computers:
Dell – http://www.dell.com/support/home/us/en/19/Products/
HP – http://www8.hp.com/us/en/drivers.html
Toshiba – http://support.toshiba.com/drivers
Sony – http://esupport.sony.com/perl/select-system.pl?DIRECTOR=DRIVER
Lenovo – http://support.lenovo.com/us/en/products?tabName=Downloads
Select your system or type it in and find the latest driver for you wirless card. There is usually a section called Networking and underneath you should see a list of drivers. One of them should have the word “Wireless” in it. If you have more than one wireless driver, then you need to figure out which one you have installed on your computer.
You can determine the model number for your wireless card by pressing the Windows key + the Pause button at the same time. This brings up the System Properties dialog. Another way to get to it is to right click on My Computer and select Properties. Once there, click on Advanced system settings.
Click on the Hardware tab and then click on Device Manager.
You’ll see a list of devices with plus signs to the left of them. Click on the one called “Network Adapters” and there will be an entry for your wireless card as shown below:
Now download that driver from the list off the manufacturers web site. Usually the wireless card is called something “Intel Pro Wirelss” or “Dell Wireless”, etc. Once you download the file to your desktop, double click on it and follow the steps to install. You might have to restart your computer.
If the driver on the computer was the problem, the dropped connections should go away completely. If not, then you might have to try updating the router firmware.
Update Router Firmware
Updating router firmware is a not so trivial task that varies depending on the router brand you happen to have. Almost none of them have an automatic update feature. Instead you have to download the latest firmware from their website, log into your router and then upload it up perform the update.
To get started, you need to figure out the IP address of your router and use that to log in via a browser. Read my post on finding the IP address for a wireless access point. Since the method to update the router firmware varies so much by brand, it’s best to search your router model number + “firmware update” to find specific instructions.
Router Settings
The last issue that can be causing dropped connections is various settings on your router. In recent times, you have dual-band routers which let you broadcast on both 2.4 and 5 GHz networks. These advanced routers normally work really well with the latest gadgets and computers, but on older machines, you can sometimes run into issues. Here’s a couple of things I would try:
1. Connect to the 2.4 GHz network if you’re currently connected to the 5 GHz one.
2. On the router, make sure the channel settings for the networks is set to Auto. If you have picked a particular channel for some reason, try a different channel.
3. Turn off extra security features like MAC address filtering, network isolation and Wi-Fi Protected Setup. None of these really increase security all that much and end up causing more trouble.
4. Make sure your wireless network mode is set to Mixed. Sometimes picking a higher mode can cause problems with older devices.
5. If you don’t know anything about your router settings, try resetting your router completely by pressing the reset button. Configure wireless security and leave it at that.
Hopefully one of these solutions will fix your wireless connection problem. If you have a different solution, please leave a comment and let us know. Enjoy!
