I have an HP 620 laptop with a Realtek RTL8191SE wireless ethernet card, and after I connect to my dorm's open wireless I can't access the internet. I receive my IP, default gateway and DNS addresses through DHCP, but I can't even ping these addresses.

However, when I connect to any other wireless network, it works like a charm. Wireless works too, but I think that's irrelevant.

The only difference I recognize between my dorm's network and any other is, that my dorm uses MAC filtering.

By the way, I can use this network with Windows 7 without any problems.

Any ideas, what could cause this problem?

can you check, whether ifconfig output shows the correct MAC address? You can configure a device to use another MAC address than its original one. This might be the case for you. Your router will just drop all incoming packages from your computer. – Michael K Nov 4 '11 at 17:28
@MichaelK - It gives me the same address as windows, so that's not the problem I'm afraid. – mrolcsi Nov 4 '11 at 18:11
