So I used a unsecure network for a while for my family to use.Then one morning waking up the network suddenly cannot work it says that windows cannot connect to network.Also the other networks are all listed on connect automatically, and I cannot change them when changed then when it disappears from sight it changes back to connect automatically.My network is the only network not on connect automatically and when trying to change it just goes back to being unchecked.When trying to connect to the network it says "Windows cannot connect to the network." please help me with this.I used a Sony Vaio laptop, Windows 7 Home Premium. I did not make any changes that I can remember since I am bad at remembering.The drivers are all up to date also.

I have managed to connect a few times though not really a connect.It stays stuck on identifying network when this happens with no internet acess.

Hi, Based on my research, please try the following: 1. Check if other computers can connect to network. 2. Follow the steps in Why cant I connect to a network and see how it works. 3. Check if reset Internet Protocol (TCP/IP) can help you. 4. Run command ipconfig /all in command prompt and let us know the result. If issue persists, please let us know more information about the unsecure network and provide us screenshots about the issue for further research. Hope this helps.

Thank you for replying, No none of the computers I have can connect to it. I have already tried the steps in "Why can't I connect to a network," no success. Also already have tried reseting TCP/IP, and no success.

Hi, Thanks for the response. However, you mentioned that none of your computers can connect to the unsecure network. Therefore, Im afraid that the issue is more related to the network than your computers. In order to determine the issue, if it is possible, please check the configurations of the unsecure network and check if your computers can connect to other wireless networks. Hope this helps.

Click start buttonDouble click control panelIn search box, type adapterUnder network and sharing center, click view network connectionsClick properties, if you see an administrator password or confirmation, type the password or provide confirmationCheck your router for compatibility

Sorry fellas but none of these worked, I do not understand the last one though what do you mean check router for compatibility.

hi.. it seems your router is stuck. is it modem and router combined? and you are having problem with wireless? can you browse 10.0.0.1? you have username and password for it? can you go into and make it unsecure to secure with password? let me know www.zon-ze.com jkim@zon-ze.com

Using another router fixed it thank you very much.
