M2 Zero WiFi chip

I’ve recently got a M2 Zero from AliExpress but noticed it says KEIIOT on that chip instead of AP6212. Did I get scammed? WiFi performance is disturbing anyway, shouldn’t there be an antenna integrated or is it because of that chip?

You need to attach antenna - you are looking at the connector.
