Basically what the title stated.

Ever since I bought the TD-W9960 , like a month a go, I had multiple issues with connectivity. at first it was constantly dropping the IP after obtaining it for like an hour or so. when I go to the settings, the only thing that's apparent to me is that the configuration gets altered spontaneously for some reason. instead of VPI/VCI , it some times switches to Vid . other times it retains the VPI/VCI mode, but the value are null and had to be re-entered. even then, it just wont work again unless I restart a couple of times or just keep switching between choosing my ISP ( We Egypt) then letting it auto fill the values, and choosing ISP : "Other" and entering the values manually.

Recently though ( for the past couple of days) , we had frequent power outages. after the first one, the router just wont connect to VDSL at all, not just fail at getting an IP like it used to. the DSL LED just keeps blinking indefinitely. I had to reset the router to get it to work again, but then it just lost it again and the same problem occurred, tried everything to get it to connect but the only thing that worked was resetting it again.

Is my unit faulty or is there something I can do about this, it's really affecting my work here.
