I don't understand the pop-up. OP was not at home, on a cellphone and I'll assume connected to a Cox Hotspot. Why would Cox script a pop-up in this scenario...while connected to a Hotspot?
In a world of phishing, hacking, scamming, spoofing, deception, malware, ransomware; a link on a pop-up offering something for free defies everything any security expert has been advising against for decades. Why would Cox encourage this behavior? If a subscriber clicked a link once and it was legit, why not click another link later?
And why was the pop-up a dead-end? And what was the link supposed to do? Log into my account, reset my modem and assume I got a speed increase at home...miles away? What is wrong with an email, a letter or a banner within my account?
Whether the pop-up was legit or not...I don't understand why Cox would not only encourage it, but sloppily script a dead link.
