We have a 300 Mbps Blast plan and the only wired service on it is our TV. We use laptops/tablets/phones off wireless for everything else. Last Friday night, everything was zipping along on all devices. Since Saturday morning, April 18, we are getting between 18 - 40 mbps download speeds and one computer can hardly function, taking 15 minutes to download something that should take about a minute.
I've reset our modem (Motorola MG7550) and nothing changes. It is worse on the oldest computer, but that computer is only 3 years old, so I don't think it has anything to do with the computer. Can anyone suggest anything else to try? Thank you.
