My attempt with support resulted in them telling me that I have to replace my 7 month old modem. I would have switched months ago, except that CenturyLink only offers 40Mbps to my house. Support did say I am eligible for some special deal to upgrade to Gig and pay more monthly, to fix my issue. Re: Will changing from 150 down to 1 gigabit down fix my packet loss/latency issues? An upgrade won't fix the issues. I seem to have to "replace" my modem every 6-8 months, and every time they recommend that I either rent, or sign up for the special deal and pay more for more bandwidth that is rarely up.
