I have an SPA112 that in sitting behind a Ubee cable modem. The internet link is solid, but the device becomes unreachable within a day or so of being rebooted. Then the customer goes to reboot the device, they report that all 4 lights are lit. The ISP reports that the device does respond to ping, so it’s not completely dead. I’ve had the same symptoms with SPA303’s sitting behind Ubee modems.
So, is there some configuration setting on the SPA that I can set to make this device more stable?
