About Intel 8th Wifi connection problem

[jack_lai]

HI ALL:

   Our ZD1200 version is "10.4.1.0 build 257" and R720 version is "10.4.1.0.257" , now we have Lenovo T480 , T490 and T14 , the colleague who use T480 always complain the wifi signal are not stable , need to disconnect then connect again , but T490 and T14 colleagues not have this issue . 

   So what config in ZD or R720 should I modify to deal with this problem !!!!
