I have a Kenmore Elite Washer and Dryer with smart connectivity. I've never been able to keep either appliance online even after placing the extender right next to the appliances. I even recently changed out the WiFi module thinking that may be the problem and I still have the same issue. These appliances will only connect to a 2.4 GHz network and I was thinking that the "high speed mode" (where it automatically disables one of its wireless bands to speed up the other) may be the problem. I turned that to manual where the extender to client is 2.4 GHz only and the appliances still dropped from WiFi. My extender is placed an appropriate distance from the router and gets good signal and the extender is right next to the appliances. Does anyone know anything else I should try?
