- Issue started after replacing motherboard.
- Cable connected to router directly. Internet/network randomly drops out anywhere from 1-30 times in a 10min period for 5-30seconds.
- No issues on other networked computers or devices.
- Computer was 4 years old and had heating issues (no network issues) but almost all parts except power supply and case have been replaced in the last year and there seem to be no other issues with hardware.
- WEIRD After turning on PC, it only happens about 80% of the time and restarting can (but rarely) fix it! Once fixed, everything works flawlessly. Restarting the router manually doesn't help but restarting it through the computer does about 70% of the time.
This part makes no sense to me, how can it only happen sometimes? How can some applications still work?
Tests:
- Set up a perpetual ping to router, get very different patterns. Sometimes packet doesn't get through for extended periods, othertimes it only drops 1 a minute.
- Swapped out ethernet cable
- Swapped router ports
- Searched the web and found many potential fixes but nothing seems to work. Couldn't find anyone with this exact problem.
- Finally I formatted hard drive, re-installed windows 10 but keeps happening
Suspected issue:
- Network card/motherboard hardware issue?
- Hardware compatability issue?
- Router/PC IP assigning issue?
