You know I feared their reputation when moving from Verizon DSL to Comcast last summer. Here in the San Francisco Bay Area but in mountain (rural) locations they have actually surpassed my expectations.
Both locations in the Santa Cruz Mountains
My home - replacing Verizon DSL - the Comcast installer spent nearly three hours running the cable from a pole across the road to the house and did a very professorial job of running the cable through crawl spaces etc to the other side of the house. He then did a very thorough test of modem signal level. The result a very reliable 20 Mbps cable service replacing an unreliable Verizon 4 - 6 Mbps service and actually saving money when Ooma phone savings factored in.
My son's home - a rental with previous Comcast service. When we activated the service on a weekend we found it was not reliable - they got it going remotely on the Saturday and set a tech out on Sunday. He spent a couple of hours testing the signals in the house and made some adjustments but eventually determined they needed to make adjustments where the service was being delivered from the main road. He had to go and get different truck (on a Sunday) with the equipment needed to do this.
Since then both my and my sons service has been very reliable.....
When I look at my Docsis 3 modem signal levels they are pretty much as good they can get.
Four bonded download channels with
Signal to Noise Ratio 35 dB 36 dB 36 dB 37 dB
Downstream Modulation QAM256 QAM256 QAM256 QAM256
Power level 0 dBmV 2 dBmV 2 dBmV 3 dBmV
Now I absolutely agree Comcast should support OpenConnect - and frankly hope Netflix and other ISP's highlight the benefits of OpenConnect (after all streaming is a major reason I and others pay for High Speed Internet) - but otherwise Comcast is doing a (surprisingly) good job of delivering High Speed Internet in remote location where both cell phone and OTA TV coverage is spotty at best.
