Default Mysterious internet/ethernet issue (kinda need testing/connection/communication service to diagnose it ???)

Oh I forgot to mention... he didn't just replace tv cable...

He also replaced the wall socket... with something new.

The one in there was very old.

He also shortened the green cable a little bit and re-attached it.

He had a nice trick though:

Instead of connecting the coax to the splitter.

He connected to coax directly to the tv.


Presumably, the splitter was being used to split the incoming signal to
two destinations, the TV and perhaps the cable modem. So how was he able
to eliminate the splitter?

This also got rid of the noise ! which amazed me !


Removing the splitter doubled the signal strength to the TV, so maybe it
was borderline low all this time. If you had visibility into the cable
modem, you'd have full knowledge of your signal levels in both
directions, down and up. Without that visibility, you're blind.

Exact problem remains unknown to some degree... we talked too much about other computer tech.

Didn't get to talking about him about cable modem menu issue...

Not sure if he could have helped probably not... but could have tried.

Maybe his excited chat about tech was a diversion tactic... not sure

It was a bit frustrating... but also kinda enjoyable... but this guy went off like a rocket... finally somebody to talk with about tech.

This guy knew almost everything there was about tech.

The only things he didn't know what how SMT/symetric multi threading worked on AMD ryzen... and L1 caches.

So I explained this too him and also showed him AIDA64 benchmark results and such...

Pretty cool chat =D


I've met and talked with a bunch of cable techs here in the States since
I first got cable Internet service in 1996. I've met a bunch who thought
they were pretty knowledgeable, but I've learned to look at it this way:
if they actually knew half of what they say they know, they wouldn't be
cable techs. They'd be network engineers of some kind, pulling down at
least 4-5 times the money.

So consider yourself lucky to get a good one over there. We don't seem
to have that here.
