Active Directory computer object parameter changed

hello experts
it has been perplex me for a long time, our company wireless network is using domain computer object authentication to connect, it is pushed by GPO.
sometimes a computer can't connect company wireless because authentication failed, tried reset computer account in ADUC but it doesn't help, i have to quit computer from domain then rejoin to fix it, so i think the computer subject must have something changed on client side or AD side which doesn't match anymore, but except wireless connection issue this computer works well under AD environment.
so you could you help investigate what is the culprit for my case?

thank you

Faulty CMOS battery, incorrect NTP configuration etc.

hi Shaun
appreciate your advice that really helpful, the last question of mine really strange few people facing it before i guess, so i get this case close, definitely this issue related with system time, also i found the most easy way to fix it without reboot the laptop, just change system time 10 min different with accurate then change it back, refresh WIFI connection and it could connected right now.

thank you
