The connections at the house are under the covered patio so I don't expect problems there. Comcast has not, to my knowledge, serviced the outside lines or box on the pole in 8-10 years. I at work since I can't reliably remote in from home so I will need to check signal strengths tonight.

I have been through most of those (not the signal strengths) with the Comcast techs. No resolution from those tech scripts. I think the problem is on the extranal comcast network or account configurations (based on prior problems and resolutions) but I don't seem to be able to get to tech support at Comcast who can deal with those issues.

I access Comcast TIVO. We get standard definition, high definition and premium channels in our package. Over the last few weeks (during which we are also having internet connection and speed problems), we are noticing that several channels, mainly HD channels such as rebroadcasts of local network channels, are just "black". Sometimes I get a message that it is searching for a signal. This seems to be a recurring and intermitten problems but it happens daily. I have tried to contact Comcast by Chat (over 3 hours the last time) to get the "black" or missing channels working. Some channels will tune in but they become distorted particularly if there is a lot of screen movement. The Comcast techs on chat have been less than helpful. They want to send resets, have me change channels and repeatedly unplugg and restart the TIVO. They did send out a new MCard and had me install that and pair it. However, none of the "scripted" steps have resolved ANY of the problems. I don't believe its a TIVO issue. I think its a problem either a) with Comcast account configuration (we actually get messages that HD versions of channels like TNT are "not authorized" but the SD versions seem to work as expected) b) a problem with signal quality or strength. Is there a number for a "upper level" tech department or are there techs on this forum who can actually diagnose and address these problems? Are there others on this forum who have had similar problems and got them resolved - and if so do you know what the problem was?

I am in Nashville and having recurrent internet "quality" issues. I have tried repeatedly to reach out to Comcast tech chat but have not been able to get to someone who could diagnose or resolve the issue. Attempts to reach chat this morning have failed. The problems are intermitten connections and repeated brief outages. I have had problems like this in the past. All of the prior problems were determined to be cable problems from house to street or cable problems on Comcast network before reaching our street "hub". Comcast has replaced cables from street to house 2-3 times and I believe replaced the street "hub" at least once. The problem - over 26 years, has never been cabling in the house itself or our equipment. Since we have not had substantial rain, its not clear what the problem is unless its either problems on the network structure outside of our home or perhaps Comcast's network cannot provide bandwidth as promised. Is anyone having similar problems? Is there a Comcast tech employee who can or will address this on the forum?

I have tried to reach Comcast tech support repeatedly for several days but "chat" techs are either too unskilled or, like this morning, just not even available. We are having repeated problems with internet service at home. It is not that we don't have internet, we do. The problem is that internet keeps dropping (several times just last night) and that when we do have internet the speed is slow. We used to have this problem when it rained extensively or got really cold but that does not seem to be the problem now. I would like to get some tech support from Xfinity with internet connection issues. I don't know if its weather related, cabling issues (we have had to have our cable from street to house replaced 2-3 times over the years), or just a high volume of other use in the area which Comcast is just not able to provide sufficient bandwidth in the community?
