I am assuming you have a ROUTER that provides the wireless networking to you. That router is connected to the ISP's modem. If so, the ROUTER issues an IP Address to you that is PRIVATE. Private ones are ones only to be used on a LAN (Local Area Network) and are not see by others. These are the range of addresses:
Private IP address ranges
The ranges and the amount of usable IP's are as follows:
10.0.0.0 - 10.255.255.255
Addresses: 16,777,216
172.16.0.0 - 172.31.255.255
Addresses: 1,048,576
192.168.0.0 - 192.168.255.255
Addresses: 65,536
There is NO 169.xxx address there. I suspect you need to use 192.168.1.1 as your GATEWAY.
To see what you have now, open up a COMMAND PROMPT and enter IPCONFIG /ALL and copy the data...
