Sorry you are experiencing this. Of course, I went through the same glitch (times three) with the malfunctioning network card in the Terra. I did have some temporary relief delaying the inevitable by unplugging for 60+seconds the terra, strato, my network switch and modem. Restarting the modem first, rebooting the router when a signal arrived, started my switch, then the terra followed by the strato. This lasted around a couple of days, sometimes even interrupting a movie playback, but I always would get it back on line by unplugging/restarting etc. Then it just stopped, forever.
