r7500v2 causing landline phone issues

My router is connected to a modem from the phone company that supplies fiber internet and phone.  Our phones started dropping out like a cell phone does when it goes out of range.  If I disconnect the nighthawk, the problem goes away.  The phone company has replaced the modem.  I have tried different cables.  I reset the nighthawk back to factory and downloaded latest firmware and I am still getting the problem.  How is the nighthawk network connection affecting the phone service in the modem?  Anyone else had this problem?

  • I have found the answer to my problem.  It was easy and straitforward.  I threw the nighthawk into the trash and am running on an old belkin until my new tp-link arrives.  I wish to thank the community for its mature and professional responses in helping me come to my solution.

       How, exactly?  (Hint: If a device has different types of Ethernet

       I know nothing about them, or how they're connected to what, either.

      I assumed there was only 1 way to connect --- from the yellow wan port to the modem.  Tried several different ethernet cables.  If there is another way to correctly connect, please let me know.

      Unimportant, the phone company brought a couple of completely different models trying to find the problem.  They, like myself, assumed it was their equipment.  The problem is with the router.  As soon as nighthawk was disconnected or powered off the problem went away.  They left one of their routers (which worked fine) while I tried to find the problem with the nighthawk.  Reset the router, downloaded latest firmware.  Tried nighthawk again and it worked for a couple of days, then problem came back.

      Doesn't matter.

      I do not think you would use dialup over fiber.  The fiber comes into the house to their modem which connects to the house phones for phone service and dsl for the router.

      > [...] Our phones [...]

      Some people still have land lines and what models are irrelevant, because the problem affected all phones.

         I know nothing about them, or how they're connected to what, either.

      I should not have to explain how non-cell phones are connected and work in a home, it is not important to my problem.

           Thanks for your assessment, but it's apparently more important to me
        than it is to you.

           That makes very little sense.  It might make more sense if I knew
        what your (apparently not simply a) "modem" actually was.

         

        > Doesn't matter.

         

           If you are so certain of what's useful information and what's not,
        then you don't really need help from someone like me, who wants to know
        more about your situation than "doesn't work".

  • As a test, I attached an old router to the dsl and then plugged the nighthawk wan port into one of its lan ports.  The phone problem stopped, but, even tho i'm still getting 100Mbps wireless, this is not a real solution.  I don't know what kind of "static/bits?" the nighthawk could be putting out that the old router would stop that messes up the fiber modem's phone port.

        Hi mark776 , out of curiosity, what router model did you bought? Did it solved the issues you had with your r7500v2?
