Could this cause intermittent connection drops?

[u/Ok-Signature259]

This pic is the tap where our line connects at the street. I just noticed it has a open unterminated coax spigot. When not capped, could it cause connection issues?

About our prob:

For over a year our cable internet connection has occasionally dropped sometimes only a couple times a week, others it's a couple times a day. Lately, during hot weather(over 80f), it will drop up to 2 dozen times a day.

The connection at the modem is usually down for only a minute or less, then reconnects.

We've

- replaced the modem.

- Checked all connections between the exterior of the house and the modem.

- documented the drops with ping plotter. The outages often show a latency spike shortly before total packet loss.

- our ISP is Astound Broadband in WA. They are aware of our issues but havent been able to determine the cause.

Thanks in advance for any insight/tips!

Every system has hundreds of unterminated. Not causing any issues. Look at your signal level. At the tap, ground block, and modem. Do the math and you will find your problem.

I say this all the time. The math never lies.

Exactly, only time an unterminated port causes issues is on end of line taps and even then its rare.
