Re: Fibe 25 upload speed decreased after install

FTTH does not use the dsl modem, it is straight ethernet.

@badabingo What xtlee said, those tools are just for DSL.

@xtlee It looks like he just added interleave. Did Bell say they will try another pair?
Fiber Optics are the future of high-speed internet access. Stop by the BBR »Fiber Optic Forum.


They said thy could open another ticket with the Test Center.
