It's not his router settings, he's already stated he tried other open WiFi networks and hotspots and resetting his network settings on the iPad also setting static IP. (however was not clear if he used the proper subnet and or separate DNS than his networks default)
There is something else amiss here.
Thomas, try the static again this time use dns from another source like dns 2go, or some similar other than one from Norway.
OK, I'll try that tonight. What's the dns2go DNS address?
I guess I could try Google's public DNS as well Using Google Public DNS
The Google Public DNS IP addresses are as follows:
You can use either number as your primary or secondary DNS server. You can specify both numbers, but do not specify one number as both primary and secondary
I'll let ya know if it works or not.
