I worry that you need to read to try other routers and of course latest firmware in this router.
If you are doing ping tests you can not have WiFi enabled on the router. Hopefully you know why.
I am getting regular ping spikes when connected with a wired connection to my router.
Using the SAME cable and PC, if I bypass the router and connect straight to the modem, there are no spikes.
Here is an example of what it looks like:
Ping test on http://www.meter.net/ping-test/. Spikes are only ~0.2-0.5 seconds long, but easily detected here, which pings several times a second. Spikes are about +200ms over the base ping.
Pinging the router in cmd: Spikes are detected less frequently since it only pings once per second and often "misses" them.
There is no packet loss, but the ping spikes are steady.
Again, I'm pretty sure it's not an ISP, cable, or modem issue, since taking the router out of the equation fixes it.
This is an old router (d-link DIR-601), so that could have something to do with it, but if possible I'd like to get it to work rather than replacing it. I did an update to the latest firmware, which helped! The spikes happened every 4-5 seconds before the update, and are more like 15-20 seconds after. It's still bad for gaming though.
Any suggestions for fixes I could make?
