非常感谢。请教：

今天comcast technitian 来买的房install internet, 他说原房主用的是dish network,房子里用的cable不能连comcast internet. 需要请electrician 重新铺comcast internet cable. Comcast does not do inside wall fishing now.

For internet service, I think comcast's is faster than dish network's. Am I right?

So I would hire someone to wire both the coax cable and ethernet line for me. In your last response, you mentioned cat 7. Do I need to have cat6 or cat6a or cat7?

Thank you so much for your help.
