I recently switched to sonic a couple weeks ago and at the end of the installation the tech guy said the speeds should vary from anywhere from 3 to 5 mb. However, I'm averaging around 2.1 mb, which is much slower than what I was expecting. Can anything be done to increase these speeds? On top of that, I've had problems with the connection dropping during the evenings. I'm definitely not a happy customer.
You can access your router at http://gateway.sonic.net/ as long as it is one of the new, Sonic.net branded devices. You will see connection speed and some other details there.
That said, if you are having reliability troubles, do phone support right away, and they can get things fixed for you!
