You are not logged in.
I am trying to connect to my uni's WLAN. It works like this: The WLAN traffic itself is not encrypted; only if you request a page that is outside the intranet you are being diverted to a login site where you have to provide a username and password. This then opens the firewall for you and lets you connect to the internet. This works on OSX on my Macbook.
On Arch however, I managed to get wicd to connect and receive the right IP address via DHCP. I can also browse the intranet (like the library resources....) but when I go to google it just doesn't divert me to the log-in page. I tried navigating to it manually but it just times out. The weird thing is that when I ping it I get a response; just when I try to access it in browser it doesn't work.
I have checked the DHCP information and I get the same IP and gateway in both OSX and Arch.
Anybody got an idea?

It's a long shot but at my school the routers are poorly configured and I get issues under linux (But not Mac OS X) due to TCP Window sizes.
My fix:
#!/bin/bash
echo 3072 4096 6144 > /proc/sys/net/ipv4/tcp_mem
echo 4096 87380 131072 > /proc/sys/net/ipv4/tcp_rmem
echo 4096 87380 131072 > /proc/sys/net/ipv4/tcp_wmem
No idea if it will help you. But worth a try.
