Lavie Tab 9QHD1 and WiFi

質問

I Have a problem with Wi-Fi Connection with Lavie Tab 9QHD1.

It cannot access to Wi-Fi, if It has no CA certification.

I just want to connect to Wi-Fi, with no CA certification like before.

Should I downgrade the its software version?

Its android version is 13

and the software version is
LAVIETab9QHD1_NEC_OPEN_USER-Q00031.0_T_ZUI_15.0.022_ST_240205

Thank you.
