Ping CANNOT be used reliably to test for latency or jitter.

It's very frustrating because nowhere on that page is there a list of which modems have the bad chips and which don't. Which doesn't help at all with the most obvious way to fix this problem: stop buying modems with the bad chips. Many people (myself included) don't trust the cable modems our ISPs provide, or don't want to pay a monthly rental on one, when we can just buy one for ourselves. If people like me had information on which modems not to buy, we could help to exert market pressure. Why do people think that the only way to fix a problem like this is to complain to the company that created it in the hope that they'll fix it out of the goodness of their hearts? When has that ever actually worked?

  It looks like at least one other site sees the same problem--and, helpfully, provides information on which modem models have it: https://approvedmodems.org/bad-modems/ https://approvedmodems.org/bad-modems/

What kind of latency issue is both noticeable and untestable?
