If your internet connection feels slow, you can take a few simple steps to reset your Cox modem and improve your speeds. First, unplug the power cord from your modem for 30 seconds and then plug it back in. Next, log into your modem's web interface and navigate to the 'Advanced' tab. From here, you will need to find the 'Reset' button and click it. Finally, reboot your computer and test your speeds again. If these steps do not improve your speeds, contact Cox customer support for further assistance.
