Re: Dropping Radio Comms from Wifi


We've been trying on both 2.4GHz and 5GHz settings with our radio's configuration, and we have noticed that both settings do drop comms at some point. After analyzing wifi congestion, comms generally seem to last longer when less people / wifi traffic is going around, and comms drops more frequently when there are more people / wifi traffic. Not to mention we were testing recently in a concrete building as our workspace.

We have taken a look at different laptops as driverstation, and all of them with the updated software still drop comms at some point. Some do work generally better than others, but even then there is still a comms drop.

We looked at the driverstation chart with the communications graph, and it does seem very predictable that comms will be perfectly fine with not much packet loss and quick reply times from radio, but suddenly after a certain amount of time it will jump to 100% loss and radio will try really hard to reconnect, but will still consistently drop packets after that.

We can still test with some of our other radios, so we will see what else shows up, but for now we are thinking the comms drops were a result of wifi congestion or interference from the building. We'll try taking our radio to some better conditions and see what comes up there.

Thanks again!
