interesting behaviors since i have the Internet service in last month.

Hello Tatat, The purpose of the Cox Internet Forum is to allow customers to discuss technical topics related to residential Cox Cable, Telephone and High Speed Internet services with other customers. This appears as if you may need for someone to look into your account personally. We can definitely be able to assist you with this. Please reach us on Twitter at @CoxHelp, visit us on Facebook, or email by at cox.help@cox.com. Provide us the name on the account with the full service address with a link to this thread so we can get started.
