Background: I'm in a noisy environment, and I'm trying to optimize my WiFi network to have a more stable connection for the somewhat high volume of users (~50-75 on a busy day). There are 4 APs, and I've already adjusted the channels and transmit power, and overall I have fairly decent coverage. However, I still get about ~10% packet drop when pinging Google and walking around the building, roaming from AP to AP.
In most WiFi APs I've seen, the default RTS Threshold is set at 2347 (from what I've read in various places, this setting counts as "disabled"), and Fragmentation Threshold is set at 2346. My particular brand of router is set at 2346 and 2346. I have several questions...
Where is the value of 2346 derived from? It seems somewhat arbitrary, however, the notes for Frag. Threshold indicates that it needs to be over 256 and an even number.
How are the RTS and Frag. Thresholds related? Their values can't be coincidence.
If modified, should they be changed together?
What's a safe value to try lowering them to, for starters?
My priority is not necessarily getting peak bandwidth for each device, but giving users a stable, consistent bandwidth/connection.
