Being able to see, but not connect to unsecured networks

    I've been moving about a bit and Ive been coming across wireless networks that are appearing as open access, but when I try to connect it just times out. Is there a way of getting around this? The only reason for this that I could think of was that maybe whoever owns the router was putting a limit on how many computers could connect at a time? :confused:

    They could be filtering access by MAC address

    Not sure what that means. Is there any way to get around it?

    Mac Address

    Em yes, it is possible to spoof a MAC address with some technical knowledge, a google goes a long way.

    Do you have permission from the owner of the access point to use it, because otherwise you may be breaking the law.

    Not sure, but could it be that you see other wifi cards in stead of Access points?

    In general, if you connect to those, you are connected but nothing happens, as there is no routing. Ad-hoc networking it is called.

    The network could be far enough way that you can see it, however, given the distance, connecting to them is unreliable/impossible. Some networks will seem open, but will need some form of subscription (i.e. hotspots).

    If they are using MAC addressing, you should interpret that as a signal that they do not want people stealing their bandwidth.
