I've been having internet issues for some time now. Browsing web pages is mostly a non issue; once in a blue moon a webpage will timeout. This happens on my wired laptop and and smart TV. My major issues are streaming and gaming. Seemingly at random the be huge lag spikes, rarely it gets so bad I get a disconnect/timeout. I'm running 75mbps.
I'm plugging my laptop directly into the modem for all testing, a Hitron CGN3 supplied by my ISP, no coax splitters. Speed tests are fine. Signal is from 5.9 - 7.2dBmV except for a single channel at 0.3dBmv on the 279 frequency. SNR is 37.6 - 40.9. The only thing that really looks off at is when I ping websites and the modem. I've gotten pings spikes in previous tests to google.com at 300+.

The modem ping is what's concerning me the most.

Is this normal? Is there something else I should be checking? What should I be telling my ISP? This problem can be as often as every five minutes and as few as once in a hour. I don't want them to run a quick test and be ignored.
答案1
I don't think this is a modem issue, because it is very rare to find a bad modem to causes like this.
I have several modems on 3G 4G Coaxial and ADSL. If you got spikes in a random way, that usually because:
- The ISP server connection issue (you can't do anything about this one)
- There is one of your programs on the computer loading something or using this resource making it spikes at random. (This is highly likely to make your connection suddenly drop high ping)
I recommend you find the second cause because it usually comes from that.
