I saw you opened three topics about the same question. I’ll ask you to not do this.
It creates an unnecessary amount of tickets for the support team and it makes it harder to focus on what needs to be answered. The next time, I’ll recommend you open only one topic with all the info and details that you have and wait for our response.
About your issue, please check the article about Networking with Torizon OS. There you can find more information about how to use the SoM as both an AP and a Client. Besides, please be sure both Client and AP mode are on the same channel (2.4 GHz or 5 GHz), otherwise, it might not work.
Best regards.
