FYI: RG-59 has an upper bandwidth pass of around 800-900MHz. Cable
companies have long been using RG-6 for their installations which has
an upper bandwidth pass up around 1.8Ghz.

I couldn't tell you what channels and ranges your cable company runs
their DOCSIS channels for cable modem bandwidth, but if your area
depends on channels beyond the 800MHz part, your RG-59 cable very well
could have had too much attenuation in the channel allocations needed
for their cable-modem setup.

Of course, this doesn't excuse the installation tech that couldn't do
basic troubleshooting, but it could very well have been your interior
wiring not being the proper type.
