看你怎么装。

如果房子已经建好，不打开墙装线比较有技术难度。cable公司的人多半不会替你做，反正他们保证cable 进家，连上modem有信号就完工了，多余的多算吧。

ethernet电缆没有什么特殊的要求，需要做个接头。不需要带computer去。comcast有自己的方法检测。接上ｍｏｄｅｍ有信号也是一个办法。

Most cable ISP companies have special modem requirement, so Moto is most likely your choice. I am using TW so the Moto modem is free. I will buy a good router with wireless attach to it.

Wireless link has bandwidth limitation that can't reach max therotical speed, eg 300Mbps or 54Mbps. Most of the time it is even slower, and has to share between machine. For wired, it is dedicated 100Mbps to 1,000Mbps.

Wireless connection is a bigger problem for older OS and machines, they tends to get slow to stall from time to time.

All in all, I have 7 PCs all wired, three laptop docks with wire as well. Only iPads and cell phones are wireless. I like my solution. :)

BTW, my TW is 30Mbps at $46 with free modem. Looks like Comcast is too expensive.

• 请问您指的是cat 6a 还是 cat 6e? cat 6a是否比cat6 对将来更便利？多谢。 -swj2000- ♀ (0 bytes) () 11/02/2012 postreply 11:03:03
