In certain routers, there is a setting that allows one to change the interference resistance, which is bounded between the limiting cases of "maximum stability" and "maximum performance." Apparently, if stability is favored, the wifi throughput is reduced, i.e. it's as if the SNR is lowered (hence download and upload rates are lowered) but somehow the stability increases. An example of such router is here. (see point 4.).
Question is, how is it able to achieve higher stability? and how come it comes at the cost of lowered throughput? Is the interference resistance simply increased by changing the frequency channel?
