From what you have given us, it sounds like you have a problem with DHCP on your router. If you have not done so, please reboot your router and then your computer. If it does not fix the problem, if you wish follow the instructions below.
There is a work around for your problem, though it may cause issues later if you add devices to your network or are on a corporate one.
If you would still like to continue, then please follow the instructions below.
1. Open up the wireless connections screen, the one that shows the available networks. This can be done by double clicking on the wireless icon in your taskbar and select "View Wireless Networks".
2. On the Wireless Connection screen, press Change Advanced Settings. This will bring up a dialog box.
3. Under "This connection uses the following items", scroll down to "Internet Protocol (TCP/IP) and double click it.
4. This will bring up another box. Change the "Obtain an IP address automatically" to "Use the following IP address."
5. In IP Address, type in the numbers 192.168.1.90
6. In Subnet Mask type 255.255.255.0
7. In Default Gateway, type 192.168.1.1
Go down to the Preferred DNS server area.
1. In Preferred DNS server type the numbers 184.108.40.206
2. In Alternate DNS server type the numbers 220.127.116.11
Click OK on the dialog box. It should ask you to restart your computer. Do this.
When it has restarted, connect to your network as you would normally. It should connect properly.
If you have any questions about these instructions, please ask me before going ahead.
