upload light on netgear cm1200 constantly drops out

I've had 3 tech appointments with the last one including basically replacing all fittings and even a supervisor came to my house. They said all the connections are great. Within 10 hours of them leaving upload light on modem starting flashing and crashed my internet. This morning it took 5 restarts of my modem to since to internet. Within 2 hours it has crashed and now no connectivity.

What do the modem's signal stats look like ? Try getting them here http://192.168.100.1 or here http://10.0.0.1

Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

What is the exact make and model number of the modem ?
