Default NETGEAR CMD31T problems

So i keep getting dropped from my internet, it works extremely well otherwise. I have Cox internet and netgear CMD31T modem. The modem seems to lose signal and reset itself many times a day. I have had 4 techs come out, the last one redid all the wiring from the box outside into my apartment. New cables have been put in, I even switched my modem for another one of the same kind. Still having the problems. Here are my modem errors and such.

I dont know what all this means, so if anyone has any suggestions or anything at all that may help I would be extremely great full. This has been an extremely frustrating process and I just want to get it fixed. I cant take the modem back and try a different one because Fry's will only give me in store credit and low and behold Frys only has 2 modems in their entire store. Go figure.
