1# Communication Subsystem - WiFi Changelog 2 3 4## cl.wifi.1 Moving System APIs and APIs of Version 9 to @ohos.wifiManager.d.ts 5Moved all system APIs and APIs of version 9 from **@ohos.wifi.d.ts** to the newly added **@ohos.wifiManager.d.ts**, and added error code descriptions. The **@ohos.wifi.d.ts** APIs do not support error code handling. 6 7To use these APIs, import the **@ohos.wifiManager.d.ts** module as follows: 8 9import wifiManager from '@ohos.wifiManager'; 10 11 12**Change Impact** 13 14System APIs and APIs of version 9 are affected. To use these APIs, import **@ohos.wifiManager** as follows: 15 16import wifiManager from '@ohos.wifiManager'; 17 18Other APIs are not affected. 19 20 21**Key API/Component Changes** 22 23| Class| API

**@ohos.wifiManagerExt.d.ts**, and added error code descriptions. 103 104To use these APIs, import the **@ohos.wifiManagerExt.d.ts** module as follows: 105 106import wifiManagerExt from '@ohos.wifiManagerExt'; 107 108 109**Change Impact** 110 111System APIs and APIs of version 9 are affected. Import **@ohos.wifiManagerExt** and use it together with **wifiManager**. 112 113import wifiManagerExt from '@ohos.wifiManagerExt'; 114 115Other APIs are not affected. 116
