Networking – Intermittent network lag when hard-wired, intermittent “request timed out” pings

lagnetworkingping

I am running Windows 7 x64 SP1.

I have been experiencing intermittent network latency issues over the past week or so.

I most often experience the problem with web page delays and timeouts during gaming…

and intermittent "request timed out"s when pinging various servers.

The problem persists, whether I am wireless or hard-wired.

Right now, I am hard wired to the modem.

I have updated drivers, reset all hardware, and restarted the PC many times.

Both my modem (and router) are three months old.

Here are the results of a few ping tests:

I have a service call appointment with my ISP tech this week, but is there something else that I can try?

Thanks very much in advance.

Given that your modem ping times out, there are only a limited amount of things that can be bad:

  • Modem is dying and thus is dropping your pings (ICMP packets)
  • Your computer is hogging the full connection and modem is discarding the packets. This can be due to a virus and given that you're hardwired to the modem with a SP1 Win7, this is not a small chance. This can also be you running higher priority traffic in volume from your machine (bittorrent) too but less likely.
  • Modem has been taken over by hacker. It may sound like a joke but this is more and more common as IoT devices are being used to generate DDoS attacks or cryptocurrency. You can only be more likely sure of this when other problems are discarded as invalid.
  • Your cable is bad and/or too long. I've seen this happen with self-made cables, cables that are run too far for their rating, and cables that are near high-voltage equipment. I'd put this as medium likelyhood but would be the first thing I would try to change.
