This is definitely not a reliable test. You're doing a speed test, over WiFi on an iPhone 6s. There are so many factors that could contribute to slower speeds including frequency, interference, range, and devices connected (If they went from 802.11n AES+TKIP it can be bottlenecked to 54Mbps.) Also if they're on 802.11b/g/n compatibility mode and a 802.11g device is connected it can also bottleneck the device. I'm sure there are issues with Comcast but this blog post identifies none.
- robalfonso 10y agoI think you have a point, however, those issues all exist regardless of the router/modem. If that is all you changed and the speeds dramatically changed, then it bears further investigation. I don't think the post is saying this is definitive. Merely that it bears further investigation. Where there is smoke there is fire.
- acdha 10y agoThis is not a widespread, comprehensive test but that doesn't mean it's not a reliable test of the limited situation described in the post. The major different I have with your comment isn't the technical aspects but the fact that the average user isn't – and arguably shouldn't be – aware of any of those details. If everyone can get significant speed improvements simply by swapping out the access point because the defaults on the ISP-managed equipment aren't appropriate for normal usage, that's a big deal — especially since they charge $150 + $10/month for that service, which would more than cover some basic config management.
