My RR in Cincy always has problems for at least a 3day streak out of every month.
It blows. REAL BAD.
Especially because it always seems to happen on the weekends.
I just call and say "yes, I reset the router, modem, and my computer, the router and computer are functioning properly, all of my cables have been tested and my problem still persists."
They insist on doing the "I'm going to send a signal to your modem" junk, even though it never works, and I can tell a tech before he walks in the door what the rating on the connection range/interferance is, and it's always in acceptable range.
Unfortunately, the best option is only for me to wait it out, and I'm convinced that they screw something up and just don't care to deal with it before they go home for the weekend, or they fail to compensate for excessive traffic during the weekends and it forced equipment to crash.
