[Non-Touchscreen Windows Mobile Other] Menneisyys:
Finally, in the list of the available connections, tap-and-hold the just added network and select “Connect” from the context menu:

[*]Now, you’re ready to connect: just fire up your client and search for nearby networks, making sure you’re not only looking for access points, but also peer-to-peer (ad-hoc) networks. This (looking for both types of network) is the default with both desktop Windows Wi-Fi clients and those of Windows Mobile; other platforms might be needed to be manually instructed to list available ad-hoc connections too.

Your new ad-hoc network will be discovered; tap-and-hold the connection and select “Connect” in the context menu. Press Next on the next few dialogs that come up. After some seconds, the networks will connect.[/LIST]

Problems:

The connection was pretty slow with my Universal. The Wizard was even worse: the Wi-Fi connection continuously dis- and, then, reconnected, making for example Web browsing even slower. In these cases, assuming you ONLY want to access the Web (and not want to run, say, Instant Messaging clients on the client), you might still want to prefer my proxy server running on the modem.

As for example Hermes users reported far better results, it might be possible the speed depends on the actual modem used.

You MUST re-edit the Registry (preferably import one of the Registry scripts I’ve provided before) each time you press the Connect button in Internet Sharing. The sole reason for this is that, by default, Internet Sharing sets back the Registry to BT PAN when it’s connected.

Currently, there’s no solution to this problem. Hope fluxist will be able to hack the DLL file so that it doesn’t overwrite the Registry every time you initiate a connection (see THIS for more info if interested).

The hack doesn't work on the MS Smartphone platform - for example, on the HTC Vox / s710, which also has Wi-Fi. That is, you can't use MS Smartphones as Wi-Fi modems.

UPDATE (10/02/2007): There is a tutorial HERE explaining how you can get rid of disconnection problems with some models. It also lets for not having to manually import the Registry script and is, therefore, recommended even for people that otherwise have no disconnection problems.

Also, there is a CAB file HERE (to be on the safe side, I’ve mirrored it HERE), which makes it possible to fill in the IP addresses on MS Smartphone (Windows Mobile Standard) devices as well. That is, with this tool, you can use MS Smartphone models having Wi-Fi support like the HTC Dash / s620 and Vox / s710. The original poster reported success with the HTC Dash / s620. With the Vox, I haven’t managed to make internet sharing work, but you may have better luck.

After installing and starting the application, you’ll need to select your Wi-Fi networking device (as can be seen in the following screenshot, it’s “TNETW12511” on the HTC Vox; if your model has the default TIACXWLN1, then, no such dialog will be presented):

You’ll, then, need to select Options / Add Profile; there, just fill in the two numbers, making sure you also give the profile a name so that it is saved and becomes selectable:

After this, you can already select the new profile:
