用康卡斯特Xfinity速度测试来查看你实际的下载和上传速度。这是个诊断工具。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/7\/7a\/Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-2-Version-3.jpg\/v4-460px-Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-2-Version-3.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/7a\/Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-2-Version-3.jpg\/v4-728px-Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-2-Version-3.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

如果连接在高峰时期速度下降，或是下载的时候速度下降，那么康卡斯特可能限制了你的宽带。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/2\/24\/Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-3-Version-3.jpg\/v4-460px-Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-3-Version-3.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/2\/24\/Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-3-Version-3.jpg\/v4-728px-Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-3-Version-3.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

查看你购买的速度是多少。 把你实际测得的速度和你购买的速度比较一下。你可以打电话给康卡斯特进行查询。如果你在前面几步发现了速度降低，你可以询问他们原因。
- 如果你达到了所付费购买的速度，但是发现它还是太慢了，那你需要升级网速。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/3\/3a\/Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-4-Version-2.jpg\/v4-460px-Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-4-Version-2.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/3\/3a\/Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-4-Version-2.jpg\/v4-728px-Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-4-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

是不是在你家里同时使用网络的人很多？是不是有人在下载大文件，比如电影或是玩网游？这也会显著降低你的网速。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/f\/f8\/Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-5-Version-3.jpg\/v4-460px-Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-5-Version-3.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/f\/f8\/Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-5-Version-3.jpg\/v4-728px-Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-5-Version-3.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

如上所述，你的邻居是不是用了你的网络，从而给宽带造成压力？每多一个人都会使网速变慢。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/d\/d1\/Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-6-Version-2.jpg\/v4-460px-Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-6-Version-2.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/d\/d1\/Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-6-Version-2.jpg\/v4-728px-Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-6-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

考虑下你的住处。 有些地方的网速会很慢。如果你住在主要城市，或是新城市，这应该不是问题。但是，如果你住在乡下或是某个基础设施很久没有更新的城市，那么康卡斯特连接设备可能已经过时了。打电话给康卡斯特寻求更多信息。
- 你在屋子里面的位置可能也有关系。试试靠近路由器。如果连接问题有所改善，那么位置可能就是问题的一部分原因了。

超负荷工作的处理器会影响速度，即使网络连接快也没用。

查看病毒软件。 首先，运行扫描病毒和其他恶意程序的软件。病毒确实会减速你的连接。 ^{[1]

研究来源} 然后，确定软件本身没有减慢系统速度。许多杀毒软件会显著减缓系统速度。
- 试着用更快的杀毒软件，如 Avast!。

有些浏览器比其他浏览器要快。如果你觉得浏览器也许是问题所在，考虑一下换成谷歌浏览器，因为这是最快的浏览器（对于大部分网站来说都是）。

检查你的DNS服务器

DNS（域名系统）服务器是一种类似于网络电话簿的东西。你的电脑是自动选择DNS服务器的，但是选到的服务器好坏的差别，就好像用20斤纸电话簿和用谷歌的差别那样大。如果别的方法都不奏效，考虑下手动寻找更好的DNS服务器。这样可以显著提速你的网速。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/0\/04\/Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-12.jpg\/v4-460px-Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-12.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/0\/04\/Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-12.jpg\/v4-728px-Make-Your-Wireless-Internet-Connection-Faster-%28Comcast%29-Step-12.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

这些程序可以找到更好的DNS服务器给你使用，较好、较可靠、名气大的就是谷歌的"namebench"程序。

修改你的电脑设置。 修改电脑的设置为自定义推荐的DNS服务器。这根据你操作系统的不同而有不同的设置方法。
- 在个人电脑上，从控制面板点击网际和网络，共享中心，再到管理网络连接。右键点击你想修改的连接，然后点击属性。点击网络，这个连接使用下列选项-属性，然后在专栏里制定一个DNS地址。
- 在苹果电脑上，点击系统参数-网络-选择你的连接-高级-DNS，然后添加一个新的DNS服务器。

如果你家很大，把它尽可能放到屋子中央。不要把它放得太靠近你的调制解调器或是任何无线设备，这样会导致线路感染（比如，2.4千兆赫的路由器会干扰2.4千兆赫的电话）。如果必要的话，买一根长网线，让调制解调器和路由器保持得足够远。

正确设置你的路由器。 输入 192.168.1.1 到你的网址框里来连接路由器，然后填写你的用户名和密码。一旦进入之后，进入“设置”，然后确定列表中有康卡斯特连接。在你第一次设置你的网络时会看到这些信息。
- 如果你还没有用户名和密码，用路由器默认的设置，这可以在路由器的说明书或是网上找到。默认的用户名一般是“admin”，而默认密码一般是“password”或是留白。
- 为保安全，修改当前设置之前记录下当前设置，这样可以保护你不会出什么意外。

考虑换一个新的路由器。 如果以上方法都失败了，问题可能是你的路由器不够快，而无法支持你购买的网速。比较一下新路由器的mbps（每秒百万字节）和你自己的旧路由器的mbps，看看你是不是该换了。如果你在玩网游或是下载大文件，你也许需要一个百万字节路由器。
- 确定路由器支持康卡斯特。有些路由器和康卡斯特的设备不太兼容。
- 试试用支持WPA或WPA2的无线G或N路由器，它比起WEP可以更好地加密。（如果你电脑或笔记本很老，确定它支持这种加密。）

小提示

如果你有（或是安装了）第二个防火墙，确定关闭了电脑默认的防火墙。同时运行两个防火墙会导致一些连接上的问题。
确保关闭除杀毒软件以外其他软件的自动更新，在你不工作的时候在集中进行更新。这样你的连接将保持高速，你也可以更新软件版本。
如果你想下载一个大文件，用下载管理器。这样即使失去连接、中断下载，你不必从头开始。
不要使用有线分流器，因为这会降低网速。
试着安装个人防火墙来帮助防止网络黑客，并控制哪些程序可以进入网络。免费防火墙包括Comodo 和Jetico。
使用杀毒或反间谍软件程序来消除占用你的网络带宽的程序。免费杀毒程序包括AVG、BitDefender和Avast!，免费的反间谍软件程序包括 Ad-Aware、Spybot - Search & Destroy和SUPERAntiSpyware。
如果你不精通电脑，就不要使用网络电话（VOIP），这可能会导致问题。

警告

如果有疑惑，就不要修改任何你不知道的设置。不正确的修改会导致网络无法使用，也会损害你的连接。
