seems like intermittently, lose internet connection. When contact customer service, they see my modem, yet when use phone app. it can not connect. the only way to correct the problem is to turn off the modem for several hours from power. when turn back on, it works for a few hours but with reduced capabilities. Return the modem and replace with same model from Cox, works for a few days, then capult - goes out again. This problem is not of my own doing or from my equipment, yet Cox wants me to pay to fix it. Question is; can I cancel service while I am under contract with Cox due to Cox not meeting obligations to provide paid for services. Have replaced modem at least five times now.
Where are you located, generally? We have been having exactly the same problem for several days - in the SoCal area.
