My 2 laptops have the ability to connect to 802.11ac WiFirouters/APs. However, even putting beside an X-1870 with lower compatibility connection setting (WPA/WPA2, 802.11b-ax), both PCs can detect both WIFI signasl with higher DB in X1870 but still keep on connecting to DRA-1360, which is its extender of it located 2 meters away from the laptop/X1870 location. Both APs are set to Smart Connect. I've already updated the driver (Intel Dual 3160/Qualcomm 9285) of both PCs but I was able to connect once to X1870 but now can't connect to X1870, even forcing by BSSID selection of WiFiInfoView application.
Is there additional settings, etc. needed to configure X1870 or my Lenovo/Asus laptops for that matter?
