DSL is a big pain in the ass!
For the past two days, my DSL has been resetting itself with some irregularity. I swapped out the Cayman router for the old DSL modem (relax, it’s still connected thru a Linksys). No joy. Then I realized that it was going down whenever I hung up the phone.
Then I realized that 2 days ago, I put in my new LCDs, and took the cordless phone off the desk. It had been connected to a line filter, but in its new home (the living room of death) it had no such thing. I put a filter on it, and the DSL has been up solid ever since. And I wasn’t using the cordless to make the calls!
Lesson: The filters aren’t there to protect the phone from DSL noise, they are there to protect the DSL from phone noise!
