Spectrum ISP supports firmware version v1.02.09 per the table provided by Netgear and I have the same issue. I haven't tried to contact Spectrum yet to see if they would update the router's firmware to a newer version or if updating to a newer firmware version would work with on the spectrum ISP. If anyone has had success with this, let us know. I will update after I try contacting Spectrum technical support with the results or if they'll even try updating the firmware.
