I have Comcast phone, Internet and cable TV. When I am on wireless Comcast high speed (Blast) Internet on my laptop, and the Comcast home landline rings, the Internet access is disconnected. Very frustrating. Any suggestions of how to change options to fix this?

Besides Jim's suggestion (which would be my first thought), there is also the possibility that the EMTA is malfunctioning. In older EMTA models, an incoming call would sometimes drop the cable modem side of things and cause this kind of issue. Solution is usually to upgrade to a better EMTA, or get a seperate cable modem and have Comcast provision the modem for HSI, and the EMTA for phone service.
Also try seperating the EMTA and the wireless router, they might not like being close to each other.

I had the same issue. If I was on my laptop and the phone rang I would lose my connectivity. My cordless phone was about 8 years old (ancient in tech world) and was found to be running on the same frequency as my wireless router. I just replaced the phone, which I had been meaning to do for a while anyway, and it works fine now.

Thank you to all 3 responders. The wireless router I rent from Comcast does not allow for different channels. But it may well be that the problem is the cordless phone, which is an older model. I will try purchase of a newer phone, assuming that will have a different wireless channel. Wilbur111

Get one of the DECT models if you want to go cordless. They operate at the 1.9Ghz frequency range, which puts them out of reach of the 2.4 and 5GHz ranges use by wifi devices.
