While you cannot access websites, did you test with their IPs instead?
Also try a traceroute.

Check your dns settings after the network comes up.*

Agreed.* Many hotels have a proxy that requires agreement to their TOS as a default first HTTP page.* You won't even be able to resolve names on the outside until this happens.* If you have a static DNS entry, you might not get the TOS page.*

Many thanks for all the quick and helpful answers!

Indeed it seems to be related to the DNS.
On CentOS, after connecting to the wireless network, I hacked the
/etc/resolv.conf generated by the NetworkManager and added Google
Public DNS to it.

I could then access all websites via their domain names.

Unfortunately, there are plenty of other issues with this particular
network (disconnecting all the time, also on windows), so I was not in
a position to test a more stable configuration.
