Yes there would dude. I really think its funny cause you do sound like you know what your talking about but you should know if it were an equipment or physical malfunction, I would be effected all the time. I also know how to look on my home router for packet loss. A simple wireshark test would tell me if I was dropping packets. So would a detailed tracert.
To just assume its a physical problem (osi model i know start at layer 1) because I had a problem with one service is pretty close minded and not very good troubleshooting IMO.
In short, It was definitely them.
Couldn't be more wrong in assuming that it would effected all the time.
The most difficult fixes in the field are what are referred to as intermittents. These can be caused by a variety of things, wind, rain, snow, heat etc.
A damaged line will short or ground out in the morning moisture in the summer, and by mid day, it's gone as soon as the dew evaporates and the ground dries out. Same with rain, and snow, and heat.
You can have a line rubbed through by a tree branch or chewed by a squirrel that works just great when it's hot outside, but goes open as soon as it cools and the damaged wire pulls apart slightly due to the colder weather. Not open enough to cause complete loss of service, but open enough to cause buffering, resyncing etc.
As for assumptions, show me where I said it was definitely a physical issue ???
I said it could be, as I've only seen it every single day of my life for the past 15 years or so. I've done about 20,000 jobs over my career, so yes, I do know a bit about what I'm talking about.
What is truly funny is calling me out on stuff you don't agree with, yet insisting you would "always be effected", which is absolutely, completely and totally false.
How many broadband or DSL/fibre optic based services have you fixed in the last 15 years ?
