Any way to determine wireless connection or cable connection via PHP or Javascript?

Question

On the website, I want to know if the visitor is using wireless or cable connection. Any way to do that?

The reason I want to do this is to offer geo location service when the user is using wireless which is more accurate than using cable. I don't want to offer this service at all when it's a cable connection because the location would be wrong.

<form action="conType.php">
I am visiting via  ...<br />
<input type="radio" name="conType" value="wireless" /> Wireless<br />
<input type="radio" name="conType" value="cable" /> Cable
<input type="submit" />
</form>
