+<li>The <b>default Wi-Fi ErrorRateModel</b> for the 802.11n/ac/ax standards has been changed from the NistErrorRateModel to a new TableBasedErrorRateModel.  Users may experience a shift in Wi-Fi link range due to the new default error model, as <b>the new model is more optimistic</b> (the PER for a given MCS will degrade at a lower SNR value). The Wi-Fi module documentation provides plots that compare the performance of the NIST and new table-based model.</li>
