Wont allow connect to internet although it connects to a network, network is fine though

NHL 10 servers are actually kinda well-known for going down pretty frequently. I wouldn't worry about there being anything wrong with your PS3 or your internet connection, it is most likely something that EA will resolve shortly. If not, though, I'd definitely contact EA and find out what the deal is.

Go into network set up a shared Internet connection using ICS (Internet Connection Sharing) You can use Internet Connection Sharing (ICS) to share an Internet connection among two or more computers on a network. First, you need one computer, called the host computer, that is connected to the Internet and that has a separate connection to the other computers on your network. You enable ICS on the Internet connection. The other computers on your network then connect to the host computer, and from there to the Internet through the host computer's shared Internet connection.
If your computer is connected to a network, network policy settings might prevent you from completing these steps.
On the host computer (the computer whose Internet connection you plan to share):

1. Click to open Network Connections.
   
2. Right-click the connection that you want to share, and then click Properties. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
   
3. Click the Sharing tab, and then select the Allow other network users to connect through this computer’s Internet connection check box.
   

I am running Windows 7 (the new vista) so I hope I can help. Go to the "Start" button and select "Control Panel". Click on "Network and Internet" and then "Network and Sharing Center". You shouls see something like: Computer =====Network ====== Internet. If there is an "X" on one of the connections, that may help you decide which option further down to try. You can keep me posted if this helps to this point.

I managed to figure it out. I had to clone the MAC address to get the router to connect to the Internet.

I still have another problem though, my laptop still won't connect to the router. I'm using Vista, is this a possible network adapter issue? My laptop is fine at connecting to other wireless networks round my friend's houses/libraries...

Check for the wireless encryption settings associated with this. If you're trying to join a network with "Open" settings to a encrypted network it won't work very well.

Your wireless card is dead, replace.

I assume that besides the 2 computers you also have a cable or dsl modem connected to the hub in order to provide the actual connection to the internet.

The problem may be the fact that this is a hub and not a router or gateway. The problem is that although it will allow you connect more than 1 computer to the internet, it does not do any good if you Internet Service Provider only supplies you with 1 IP address. You need something that handles Network Address Translation (NAT), like a router or gateway device.

Always tell us the make and model of your system and the operating system you are running.
In your case, you should also mention how you connect (when you do).
