I saw a TV news story that said power transformers acted as ''speed bumps''

the powerline Internet service still slower than competing technologies?

The BPL Internet provider would install an RF bypass circuit on each
power transformer to allow the digital signal to go around the
transformers and continue along the power lines. The big problem with
this technology is that digital signals are rich with RF harmonics,
including shortwave frequencies, which would be radiated from the power
lines and be received by shortwave radios as noise or interference. It's
becoming clear that the FCC doesn't really care much about the
interference issue when there is so much money to be made by this new
technology. Shortwave listeners don't have any influence in Washington
like the BPL industry does. It's the old adage that money talks.
