I have been through it all and have have 3 tech visits and numerous phone calls. After my own trial and error it appears the main cable box is causing my Xfi Arris Modem to disconnect and reset every hour. I took the cable box back and got a different model (without DVR). Still having the same issue. I have reset everything and have tried powering on the modem first then cable box. The connections look tight and fine. Tech replaced some connectors and tightend everything. I even plugged the modem into a different power strip. What in the cable box would send a kill signal back to the modem? Help!!!
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 ?
