I just got my Yahoo! DSL self-install kit in the mail, and the modem has a red sticker on it that reads:
"ATTENTION To maximize connection speed, leave this modem on for 10 days after DSL installation is complete. Please Note: You can use your DSL service during this time. It is not necessary to leave your computer on, only the modem."
Why do I have to leave the modem on for 10 days? Is something inside it fermenting? Email me if you know.
