Every time my daughter cranks up her fire HD8 it knocks out my DSL modem. Doesn't do it immediatley, but eventually the modem will drop. Sometimes immediatley...sometimes hours later. We have 2 computers wired to modem and a Firestick, but it must be the HD8 causing the problem, because the Firestick is unplugged and not being used. THis started happening when we won a Firestick and a HD8 at the same time. So, we started using both those new items at the same time. However, like I said, we have the Firestick unplugged and the modem is still going out. Modem has had to be reset 4 times today! Any ideas?
