Re: [Signals] COMCAST said my E2500 router is causing leakage. You do not need to RENT a modem/router from Comcast and pay them an additional fee every month just because two random people say your router is causing problems.
Personally I would simply continue to use everything like you were before. IF and a big IF some guys return and attempt to disconnect your service then contact your local office or the corporate office and get to the bottom of what they claim is going on. I'd be willing to bet that you don't hear anything else from those guys though.
