如果房子已經建好，不打開牆裝線比較有技術難度。cable公司的人多半不會替你做，反正他們保證cable 進家，連上modem有信號就完工了，多餘的多算吧。
ethernet電纜沒有什麽特殊的要求，需要做個接頭。不需要帶computer去。comcast有自己的方法檢測。接上ｍｏｄｅｍ有信號也是一個辦法。
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.
