Does anyone know how fiber optic phone lines can affect connection speeds with dialup service. For instance, my 56k modem, gets 22k. It's never done better unless I take it to a different location out of this area. I'm across the street from the local phone switching office as well. The phone company says it's the fiber optic lines.

Fiber Optics Involved:
When fiber optic cable is involved in getting your telephone call from your home to the telephone company switch that connects your call to its destination, analog to digital conversions must take place. When more than one (1) conversion takes place, there is degradation in the quality of the call. Your home phones are analog and the switch at the phone company works on analog signals as well, so any conversion to digital on fiber has to be
converted back to analog at the phone company thus resulting in a connection speed NEVER higher than 33.6kbps.

Thank you very much, that explains it for me. The last time the phone company worked on my line, they said they put me on a separate pair, which runs 100ft into a large switching box. Cable in my future.

Guess there's not much that can be done to speed this up...other than cable? I tried a certain string in the modem once, and it would indicate a very high speed, something like 100k, but that was a false reading I believe.

Windows ME Since installing ME the modem is shown as Lucent Winmodem, but installed a different brand that I bought at Office Depot. Can't find the box, and forget what it was, V.90 56k I know. And I hope this is the log: It shows 28800k, but test pages show 22k consistently. Thank you Charles:

I would update the drivers to the 8.30
first.Note after you update the drivers the modem will be called agere modem,need to check dial up properties to make the change.
