网速感觉很慢

网络繁忙

Internet service providers commonly setup internet connections so that they are shared between several households. Even though you connect separately, through your own phone line or cable connection, the connection to the rest of the internet at the telephone exchange might actually be shared. If this is the case and lots of your neighbors are using the internet at the same time as you, you might notice a slow-down. You’re most likely to experience this at times when your neighbors are probably on the internet (in the evenings, for example).

一次下载很多内容

如果您或别的什么人，使用网络同时下载很多文件，或者在看视频，网速可能会力不从心达不到要求，在这种情况下，就会感觉网速慢。

不可靠的连接

一些地方的网络连接确实不稳定，尤其是临时场所或连接要求多的地方。如果您在一个繁忙的咖啡店或者会议中心，网络连接可能会非常忙碌或者变得不稳定。

弱无线连接信号

If you are connected to the internet by wireless (Wi-Fi), check the network icon on the top bar to see if you have good wireless signal. If not, the internet may be slow because you don’t have a very strong signal.

使用的移动网络连接速度较慢

If you have a mobile internet connection and notice that it is slow, you may have moved into an area where signal reception is poor. When this happens, the internet connection will automatically switch from a fast “mobile broadband” connection like 3G to a more reliable, but slower, connection like GPRS.

Web 浏览器有问题

Sometimes web browsers encounter a problem that makes them run slow. This could be for any number of reasons — you could have visited a website that the browser struggled to load, or you might have had the browser open for a long time, for example. Try closing all of the browser’s windows and then opening the browser again to see if this makes a difference.
