<div dir="ltr"><br>Hello, recently i buy witi board from MQMaker Indiegogo (<a href="https://www.indiegogo.com/projects/witi-board-open-extensible-router-nas-platform#/" target="_blank">https://www.indiegogo.com/projects/witi-board-open-extensible-router-nas-platform#/</a>)
 the problem is in wifi chip MTK7602E and MTK7612E, and i think that 
problem is in eeprom settings. Maybe the witi board creator didn't make 
wifi calibration! Manufacturer of the chip MTK hightlight one feature <span style="font-size:0.875em;line-height:1.71429em;color:rgb(53,54,48);font-family:RionaSans,Helvetica,sans-serif;background-color:initial">Calibration Free (iCal).</span><br>What that this means?<br><div>(<span style="font-family:Verdana,Helvetica,Arial,sans-serif;font-size:12px;line-height:18px;background-color:rgb(250,250,250)"> </span><a href="http://www.mediatek.com/en/products/connectivity/wifi/home-network/wifi-ap/mt7602e" style="color:rgb(153,0,153);text-decoration:none;font-family:Verdana,Helvetica,Arial,sans-serif;font-size:12px;line-height:18px;background-color:rgb(250,250,250)" target="_blank">http://www.mediatek.com/en/products/connectivity/wifi/home-network/wifi-ap/mt7602e</a>).</div><div>It
 is possible to change some eeprom values for chip, but is it possible 
in non laboratory environment just with oscilloscope(what type- freq. 
range needed) to roughly calibrate wifi chip?</div><div>What would be procedure?</div></div>
