the rix mix

I'm on 56K free Juno dial up service. My DSL signal is entering the modem & not exiting it  to the PC. Happened all of a sudden. Steady red light on the output.  The last time I had a problem I had better luck with Juno's phone help; the e mail was useless. The phone guy found the problem in the signal coming into my phone & fixed it remotely. According to the modem diagnostic test, that's the not problem this time. It's also not Windows according to that test.  Oh well.
