Internet DSL Keeps Disconnecting / Possible DNS Server Error

A few days Ago we finally got our 24Mbps DSL package and so far it keeps disconnecting every 30 mins (sometimes more, sometimes less). The thing is I'm living in some village in Ukraine so there's only one ISP I can choose from and the phone lines here are a piece of crap (I can hear the static, but I can't do anything about it.) Calling the phone company is out of the question as no one here would even think about improving our phone lines (trust me, this place is FAIL). Also, My ISP is bsing me into believing that I'll get 24mbits on some crappy copper wired phone line that makes noise every time you try to use the phone. I'm using a 5 port switch to connect 2 computers to the internet through some so-so modem. The ethernet cables are not cat5 quality either and the phone cable is just some average RJ11 type deal. Now I know the true meaning behind "up to 24mbps downstream and 3 mbps upstream!" which is actually means "10.5mbps down and 0.3mbps up (at max)". Yes, I live more than 2km from the providers. [code]
