@@ -25,17 +25,6 @@ The **Cellular** tab contains the following configuration parameters:
 - **APN**: defines the modem access point name (HSPA modems only).
 
 - **Auth Type**: specifies the authentication type (HSPA modems only).
-    This parameter is mandatory for standard profiles and optional for generic ones. 
-    In the case of generic profiles, if it is left empty, the value is automatically picked up from the Mobile Broadband Provider the modem is registered to. If a value is filled, the APN value is explicitly configured.
-
-    To avoid misconfiguration issues, it is strongly recommended to set it manually.

-        A good practice is to set the interface status to **Disabled** and then **Enable For WAN** when the APN is explicitly set. NetworkManager, indeed, will fallback to the default value if a wrong APN is specified, causing misleading behaviors. This does not happen if the interface is disabled and re-enabled after APN changes.
