US Cable Support > Bright House Networks > Constant disconnects

First my setup, BHN netgear cgd246 to Asus NT-56U router.

I am having disconnects from internet in both wireless and wired connections. This has been going on for almost a month now, have had 3 techs out, and I still am having problems. First tech replaced the modem, second tech saw the connection dropping out to nothing and said he put in a service call for outside work, 3rd tech knew nothing of the outside service call and the internet was working fine when he was here. I am supposedly on "monitoring" now but I haven't heard anything back. I still have no stable internet and its worst between 2pm-2am.

I am screwed as the only highspeed internet in my area is brighthouse, only other options are DSL.
