    On the TCP/IPv4 , i set my IP address to be obtained automatically as well as the DNS sever address, technically the DHCP should be enabled, but when i verify using the cmd (ipconfig/all) the result is (DHCP............NO) only for the Tunnel Adapters, but YES, for the other ones, is that normal? I am having a problem with my ADSL dropping each time my homephone rings or when i make a call from it, the network icon on the taskbar gets the yellow sign, then i right-click on it and click "troubleshoot problems" > result : "DNS server isn't responding" , by the way, i'm using a filter with dual outputs, one for ADSL and one for the homephone, i used 3 different filters from 3 different manufacturers but the problem never gets solved, someone told me it might be the cable being an old non- optic fiber, i'm fed up i need help!

    in the same spot where you set the dhcp on ipv4, the button below that is for dns. set the dns server to and the one under that to those are googles public dns servers. see if that helps, it should fix the dns server issue, but i wouldn't think that would cause your problems with dropping service when a call comes in. but i'm no expert on dsl internet.

    I don't know how to fix your problem.

    But I will mention that it is normal not to have DHCP enabled on the tunnel adapters... not really sure under what conditions they get used, but in most ordinary setups they play no part in your internet operations.

    I will also mention that there are very many of us living with old copper wires. Especially for those of us a long way from the central office, that means we have to settle for fairly slow connections: mine works out in practice to somewhat under 3mbps download, and they tell me that is the best they can do. But it does work, pretty reliably, and I have never had a problem with interactions between voice calls and the dsl service.

    It is not clear how that interaction happens. The filter is to keep the high frequency DSL signal out of the analog telephone equipment. There is usually no filter on the DSL side... the modem should work fine connected directly to the line, ignoring any low frequency analog signals that might be present.

    If somehow the filter connections were reversed, so that the DSL signal to the modem is attenuated while there is a low impedance connection to the phone, then I could imagine that picking up the receiver could kill your DSL. And reversed connections on the filter could account for other problems, due to the resulting very weak DSL signal at your modem.

    But if you have tried several different kinds of filters and thus looked at the hookup several times, it does not seem likely that you have the connections reversed. So I don't know what to tell you... it may be that you need to get your provider to run a line quality test, looking for a poor connection.

    Any other phone jacks? If so, the problem could be a missing or defective filter there.
