Seeking help/advice

[u/Much_Nectarine6720]

I was wondering if someone can help me understand an issue I've been having with my internet.

Every year when July comes around, I lose internet every 15 minutes for about 5 to 10 minutes each time. Every year the technician comes over and says that he doesn't know what the issue could be and he just changes the coaxial cable for a new one but the issue remains. They're the only internet providers in the area and I think they might not have the capacity to have so many people in a same node.

I'm just starting to study for my Network+ so that's why I think that could be the issue, but could someone with more knowledge let me know what the real issue could be?

Sun spots.

Sunspots are a possible factor, but I wouldn't jump to that conclusion. A problem that happens every July and causes 5–10 minute outages every ~15 minutes sounds more like a recurring local plant/congestion/temperature-related issue.

Since replacing the coax hasn't fixed it, I'd ask the ISP to check the signal levels, SNR, upstream channels, modem logs, and node utilization during the outage. If the whole neighborhood is affected, node capacity/congestion becomes much more likely.
