Okay , this is going to be a very long post . So bear with me here

I have an acer aspire 5742g laptop . I use wifi at my home , and the wireless network seemed to work fine there.

Then after a few days I came to the hostel . We have wifi in the hostel , so I tried to connect my laptop with the wifi . And there is a message that came , "Unable to connect to stes(name of the wifi network ) , earlier I thought that it was a temporary thing and that it would work the next day, but then the next day , my room mates arrived and their laptops connected easily without the error message .

1)When I click on the wifi icon on the right hand side bottom bar , I can see the network , but it does not connect , and gives me the same error message .

2)When I click on Network and Sharing Center , and then on manage wireless network , I don't see the name(stes) of the wireless network(So I can't even remove it)

3)I have tried uninstalling,installing,updating my network adapter , drivers etc . but none of the things have worked .

I can't seem to figure out what the problem is . Its really bugging me now :| , I formatted my laptop , restored it to factory settings , nothing worked.


I also tried to connect through a hotspot which I made from my mobile and it got connected easily without any problem .


Can anyone help me out here ?

Please attach a screen shot of the Networks page (don't collapse the Radar, Connection or Signal History) of the Xirrus Wi-Fi Inspector. If you need help with that see TSG Posting a Screenshot. FWIW to take screen shots with Windows 7 or Vista I prefer to use the built-in Snipping Tool.

Identify the desired network and also show ...

Open a (black) Command Prompt window:
Hold the Windows logo key and press r; in the Run box type cmd and click on OK.

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

I can't see any clues to the problem.

I'm wondering if a firewall or security suite could be configured (or corrupted) to prevent connection to an unsecured network and result in that message. What firewall or security suite is on the system?

Make sure you have the latest wireless driver from the laptop manufacturer's web site.

Let me change my last question ...

What firewall or security suite is, or ever was, on the system?

If you're connected to a hotspot or domain network, contact the network administrator. Otherwise: 1. Unplug or turn off the device. 2. After all the lights on the device are off, wait at least 10 seconds. 3. Turn the device back on or plug it back into the power outlet. To restart a router or access point that has a built-in battery, press and quickly release the Reset button.

then I formatted the system
if you used the recovery CDs that come or are built from the PC - I suspect that there could still be trial ware on the PC
