R6300 Poor Local Ping.
Hello there! I have an R6300 router. The router is connected to a cable modem and off out to the world. Everything is hard-wired and I have tried replacing cables and so on. All transfer speeds see...
There are two factors:
- When the R6300 receives the traceroute packet, it needs to handled directly by the router's CPU. This can take longer than packets going through the router out to the Internet, which can be handled entirely through the hardware accelerated data path.
- Enabling certain features on the router, including QoS, traffic metering, port forwarding, PPPoE, site blocking and MAC address cloning disable hardware acceleration. This forces to CPU to handle all packets, including those going through the router. Of course, this will impact the router's ability to process traceroute packets in a timely manner.
So, what does this really mean? Don't worry too much about the traceroute latency to your R6300. 9 ms is not a problem. If you haven't disabled hardware acceleration, this latency may not be correlated at all with the latency to the Internet. If you have inadvertently disabled hardware acceleration but you need the lowest latency possible (i.e. you are a gamer), then you may want to consider disabling all of the above features. You need to reboot the router before hardware acceleration is re-enabled.
Thank you for the great reply. Just one question, what exactly do you mean by "hardware acceleration"?
"Hardware acceleration" refers to ability of the router to process and forward traffic without involving the general purpose CPU. The packets are handled by the router's chipset (i.e. Broadcom, Qualcomm, etc.). It's similar to processing video through a computer's GPU or CPU. The GPU can do it much more efficiently and faster than the CPU.
How is this changed then? I can't see any setting for that.
