Problem with WLAN Access Point

[den1s]

I'm trying to create an access point to connect two devices via an ad hoc connection, but i'm having a problem. The access point my device creates is in the commdb list, but others devices can't locate this access point.

	CCommsDatabase* db = CCommsDatabase::NewL();
	CleanupStack::PushL(db);
	TInt err = db->BeginTransaction();
	
	// Create a wlan AP and fill its mandatory fields.
	CApAccessPointItem* wlanAp = CApAccessPointItem::NewLC();
	CApAccessPointItem* wlanNewItem = CApAccessPointItem::NewLC();
	
	wlanAp->SetNamesL(_L("WRS_AP1"));
	wlanAp->SetBearerTypeL(EApBearerTypeWLAN);
	wlanAp->WriteTextL(EApWlanNetworkName, _L("WRSAP1"));  
	// Give correct Data as per the router configuration  //L!nkSys@MdpNok!a
	
	//Lan network mode should be 1 for infrastructure, 0 for adhoc
	wlanAp->WriteUint(EApWlanNetworkMode,1);
	
	wlanAp->WriteUint(EApWlanChannelId ,3);	
	
	// Setting up advanced settings for IP addressing
	wlanAp->WriteTextL(EApWlanIpAddr ,_L("192.248.16.30"));	
	wlanAp->WriteTextL(EApWlanIpNetMask ,_L("255.255.255.00"));
	wlanAp->WriteTextL(EApWlanIpGateway ,_L("192.248.16.30"));
	
	TBool val =ETrue;
	TUint32 newalanid;
	
	CApDataHandler* handler = CApDataHandler::NewLC(*db);
	TUint32 apid;
	apid = handler->CreateFromDataL(*wlanAp);
	handler->UpdateAccessPointDataL(*wlanAp,val);
	handler->AccessPointDataL(apid,*wlanNewItem); 
	
	CApUtils *aputil = CApUtils::NewLC(*db);
	TUint32 wapuid = wlanAp->WapUid();
	TInt Iap = aputil->IapIdFromWapIdL(wapuid);
	
	wlanNewItem->ReadUint( EApIapServiceId, newalanid );
	TBuf<50>	ibuff;
	wlanNewItem->ReadTextL( EApWlanNetworkName, ibuff ); 
	TUint32 newAPId = wlanNewItem->WapUid();
	
	CCommsDbTableView* wLanServiceTable = db->OpenViewMatchingUintLC( TPtrC( WLAN_SERVICE ), TPtrC( WLAN_SERVICE_ID ), newalanid );
	
	TUint32 errorCode;
	
	errorCode = wLanServiceTable->GotoFirstRecord();
	
	TInt leaveError = 0;
	
	if ( errorCode == KErrNone )
	{
		wLanServiceTable->UpdateRecord();
	}
	else
	{
		TUint32 dummyUid( 10 );	//KUidNone
		leaveError = User::LeaveIfError( wLanServiceTable->InsertRecord( dummyUid ) );
		wLanServiceTable->WriteUintL( TPtrC( WLAN_SERVICE_ID ), apid );
	}
	
	wLanServiceTable->PutRecordChanges();
	err = db->CommitTransaction();
	CleanupStack::PopAndDestroy(6);
	
//server is a RConnection object and connection is a RSocketServ
    TInt error;
    error = server.Connect(KESockDefaultMessageSlots);
    error = connection.Open(server, KConnectionTypeDefault);
    TCommDbConnPref prefs;
    prefs.SetDialogPreference(ECommDbDialogPrefDoNotPrompt);
    prefs.SetDirection(ECommDbConnectionDirectionOutgoing);
    prefs.SetIapId(Iap);
    error = connection.Start(prefs);

What could be wrong? I'm stuck with this code for weeks and got no solution...

Read the comments in your code snippet.

//Lan network mode should be 1 for infrastructure, 0 for adhoc
wlanAp->WriteUint(EApWlanNetworkMode,1);

I was using 1 to see if it could make any difference when other device trys to find the access point, but my biggest problem is the fact that the access point that the device creates isn't seen by any other device. It's not about being adhoc or infrastructure.

Just for verification, you could try creating the access point manually, and check if other devices happen to find it in that case (after powering up the interface with a simple "error = connection.Start();" of course).
For setting the addresses and the channel, use the Advanced settings from the menu.

wlanAp->WriteTextL(EApWlanNetworkName, _L("WRSAP1"));

may be the WRSAP1 is not exist?
or WRSAP1 signal is very bad?

Generally he wants to create an Ad-Hoc network, so WRSAP1 does not have to exist. The posted snippet is a broken one I assume.
