You can also tell Windows wireless services to "not" connect to unsecured networks. This is done through Start/Settings/Network Connections where you should find the configured wireless device. It's quite possible that you've not connected to your own ISP if you've just allowed random wireless connection. You should look for and connect only to the SSID of your router.
A few days ago i was trying to configure a wireless network, and without seeing the create wireless network setup wizard option in control panel, i used network setup wizard. the first option was that my computer connected directly to the internet and other computers were going through it. the other was that my computer was going through a residential gateway or another computer. i thought this meant router so i checked it. I think in reality both computers go directly to the router. after this it did some configuring which made me have to restart my computer i think this is what caused the ip conflict because it started after this. but i could be completely wrong as i was messing whit other things i shouldn't have been messing with (these i can't remember).
While trying to connect to the router, it stops at "acquiring network address" and the network connection panel says my ip and subnet mask are 0.0.0.0.
I have tried using run-cmd- ipconfig/release (/renew) and also turning off all devices so it resets.
Thanks in advance any help is appreciated.
