[ask] ping time unstable

i' have the problem with my wireless PTP

whether there is another setting for my wireless to be more optimal??

What are your CCQ values? I bet they are not always 100/100% when sending heavy traffic? Sounds like the wireless is doing what it is supposed to do, it is seeing other traffic on the radio channel and is delaying transmission or retransmitting the packets. This is then causing latency.

What does a frequency scan show you about the traffic around you? Is it busy?

Choose a different channel, choose a different aerial that only "sees" your clients and less interference.

There are other options available in v4, such as turning off CSMA and only using nstreme polling to control packet timing. But go for the easy things first!

whether they could provide example settings to use
:D
