I had been having intermittent internet issues with my old Orib router and recently upgraded to the CBR750 so I could leverage 1 gig speeds offered by my provider. Soon after a month of solid use I began getting the T3 time-out errors. I called netgear support and tried several things they suggesting and they recommended I have a technician come out so I began troubleshooting my configuration. I have a splitter so I decided to plug directly into the line coming into the house. When I did the the T3 errors on router startup went away so I began by adding the adding the splitter and then second connection to the splitter (which still worked) and identified a bad cable between my splitter and modem. Once I swapped it out for a different one (and purchased a new quality one) I have not had any issues. I hope this helps someone since it's important to have quality cables.
