Bridget had to replace the ONT, because the first one was only giving us 200Kbps down (2Mbps up), but the second try was the charm. With the new ONT, I was getting close enough to the quoted 15Mbps download/2Mbps upload speeds of my package to be happy.
Fiber broadband speed bliss!
For reference, the page Bridget always uses is www.speakeasy.net/speedtest, using their San Franciso server. She says that all of their other servers aren’t fast enough to accurately test Fios speeds.
