    I have a new shared network thing called "BLACKHOLE" in my network, I know its not from the WiFi network I'm connected to because I set it up and I never created that... Anyone know whats going on?

    Did you secure the wireless network you set up?

    Log into your router or access point and check out connected devices. Correlate each MAC (hardware) address to machines you know are yours.

    This looks to me like someone is taking a freeride on your network.

    A simple test is unplug your WiFi, and restart your computer. If it's still there, then you're right that it's not from your wireless network.

    The network is secured but only with a WEP key, the reason being its not got a long range.

    Thing is, the network is set up through internet sharing on my iMac, and I'm not sure how to view connected devices... I'll explore, though.

    WEP is insecure, and should only be used if you've actually got devices that can't handle WPA.

    That said, from the pics it seems this network is showing up on your MacBook, is it also appearing when you browse the network from your iMac?

    The Network folder in the Finder often retains the server list from a Network you've previously connected to (which is fixed by a restart, or connecting to another network that actually has servers available). So, if you connect to a university network where others are connected with sharing enabled, you'll get a list of servers. If you go home and browse network servers, you might still see some of those that were present on the university server.

    I know, WEP can be cracked in under a minute, but its the only thing the iMac will let me choose for internet sharing encryption, which is really annoying.

    It dosent show up on my network list, just the server one. I dont think I've connected to any other networks recently, it just randomly appeared last night... I will reboot now and see if it helps.

    EDIT: Its gone after a reboot! I just hope someone didnt connect to my network and download illegal content with it!
