[Speed] Have just received my 3rd mailing about Speed Increase

Though I got speed increase earlier in the year.... I've since received 3 separate mailers telling me how they've just increased my speed, and suggesting that I power cycle the Modem (Arris Box in my case) to get the "New Speeds".... I fell for this the first time I got the mailing.... but I was already at 50Mbs.... so nothing happened other than log a power outage on the Arris Box... But I've since received 2 other mailings separated by a month or more, saying this... Gee, I wish they'd save the money... -- Looking for 1939 Indian Motocycle
