Setting up a Motorola VT2x42 for VBuzzer

Important: the Motorola VT2x42 series of routers are compatible with Vbuzzer. However, when you create your Vbuzzer account, use only the following characters in the user name: the letters a through d (lowercase) and the numbers 0 through 9 (valid examples of user names: abc123, dba999999, ababab1234). Update: this limitation appears to have been removed in firmware 12.0.1.
