Is there a way to connect to hidden wireless networks

[kcahow]

We have the requirement to be able to connect to a hidden wireless endpoint, one that is not broadcast. Is this possible right now?

Not without modification, but it should be pretty easy if you want to test it. Can't guarantee that it will work though.

I am not sure how connecting to a hidden endpoint is supposed to be implemented, but my guess is that you manually need to specify all the network settings that the OS normally provides when it finds a wireless endpoint.

The modifications you probably need to do to test are:

Change Wifi._client to be a public variable.
Change AccessPoint constructor to public.

Test script part:

Define the access point settings manually

The wireless access point settings are returned by OS as the WlanAvailableNetwork struct, start with manually creating an instance of that one with the following properties specified to match your hidden network:

• dot11Ssid.SSID
• dot11Ssid.SSIDLength
• securityEnabled
• profileName
• dot11DefaultCipherAlgorithm
• dot11BssType

Get your hands on a WlanInterface

Create an instance of Wifi, then you access WiFi_client.Interfaces which is an array of all your wireless network cards. Grab the first one and store in a variable.

Instantiate and connect to AccessPoint

Create an instance of AccessPoint where you pass in the WlanInterface you just retrieved and the WlanAvailableNetwork you defined with your network settings.

Then just run the method Connect() on the AccessPoint and it should connect to the wireless network. If it does not, a ToString() on the AccessPoint should give a hint for the reason.

Thanks,

I will give it a try. I was going down that rout but getting it all messed
up. I will re-try it again tomorrow

Thanks

@kcahow How did your test go?

[aaronczichon]

How to create an instance of AccessPoint without an constructor? I also trying to connect to a hidden network...

[DMDTT]

Is there any progress?
I always get a Scan_Failed response

`var network = new WlanAvailableNetwork();
network.dot11BssType = Dot11BssType.Infrastructure;
network.Dot11PhyTypes = new Dot11PhyType[] { (Dot11PhyType)7, Dot11PhyType.Any, Dot11PhyType.Any, Dot11PhyType.Any, Dot11PhyType.Any, Dot11PhyType.Any, Dot11PhyType.Any, Dot11PhyType.Any };

        item.SSID = "Test1";
        item.Key = "12345678";
        network.dot11Ssid = new Dot11Ssid
        {
            SSID = Encoding.ASCII.GetBytes(item.SSID),
            SSIDLength = (uint)item.SSID.Length
        };

        network.dot11DefaultAuthAlgorithm = Dot11AuthAlgorithm.RSNA_PSK;
        network.dot11DefaultCipherAlgorithm = Dot11CipherAlgorithm.CCMP;
        network.securityEnabled = true;

        AccessPoint ap = new AccessPoint(new WlanClient().Interfaces.FirstOrDefault(), network);
        network.profileName = item.SSID;
        var authrequest = new AuthRequest(ap);
        authrequest.Password = item.Key;
        bool connected = ap.Connect(authrequest, true);`

with ap.ToString() returning
Interface: WLAN 2\r\nAuth algorithm: RSNA_PSK\r\nCipher algorithm: CCMP\r\nBSS type: Infrastructure\r\nConnectable: False\r\nReason to false: Success\r\n"

I think the maintainer is no longer supporting this library.

[DMDTT]

@Inoverse did you manage? did you find a workaround?

[aaronczichon]

Nope. It's over a year ago.
Also don't do .Net anymore. Sorry.

see #32

I got it to get it working on our environment
