I use Charter Communications as my ISP. At one outlet in the house I
have a CTV splitter to connect to both a TV and my cable modem.

Worked well for 2 years. Then, all of a sudden, no internet service.

Chater finally asked if there was a splitter. When removed the internet
service returned. Replaced with a new, more expensive splitter and all
is well with both TV and internet.

Charter said that splitters go bad. Rarely, but it does happen.

Wondering how a splitter can go bad. Isn't it a simple voltage divider
with an impedance match to 75 ohms? Are there capacitors in there that
could go bad?

Figured someone here would have opened a splitter at one time or another.

Thanks.
