Yeah - I’m in the 95th and Cicero area and I have Comcast - I’ll have to try them again and see what happens.
Another thought:
I was having problems a year ago. Four different crews came out and checked stuff.
Finally, one guy said it might be my cable modem. [I had purchased it from the cable co 5 years earlier, when I first got cable internet.]
He said the problem was that the modem was too old to handle the increased speeds the cable internet had periodically upgraded. [When I first got it, the high speed was about 1 MB. Last year, it was 7 MB and it is up to 9 MB now.]
I bought a new cable modem. It did help. Of course, they had problems in their lines, too, that they finally got resolved.
