    I have a dell laptop with Windows 7 installed. I have a ubuntu 10.10 installed on the same computer. The Internet was working fine till yesterday on both O.S. But due to the some odd reason I could not access Internet on Windows 7 but in ubuntu it is working fine. Actually, I am using ubuntu to post this message.

    I haven't changed the network setting and am using the same wi-fi. The troubleshooting centre gave this message

    "Resource (web proxy) is online but isn't responding to connection attempts. The remote computer isn't responding to connections on port 3128 , possibly due to firewall or security policy settings, or because it might be temporarily unavailable. Windows couldn't find any problems with the firewall on your computer

    I am using firefox on both. On both internet was working till yesterday.
    I am accessing a public wi-fi network which uses 10.0.0.3 and 3128 port.
    I am using Microsoft security essentials and no 3rd party firewall.

    This is the first time I have seen this error. I found things about disabling proxy but my wi-fi wouldn't work without that. What to do?

    Try a system restore, to a restore point just prior to yesterday.
    If that fixes things than it's likely that some install (maybe even a Windows Update wireless adapter) has caused the issue.

    A new development.
    I uninstalled my ubuntu 10.10 and installed ubuntu 12.04LTS. wifi wasn't working on that either. Had to go back to ubuntu 10.10 to post this message.

    Link to ubuntu forum discussing this
    [ubuntu] wifi not working on ubuntu 12.04LTS and WIndows 7 but works on ubuntu 10.10 - Ubuntu Forums

    EDIT:
    Can now connect to the wifi in Ubuntu 12.04LTS. Windows 7 still not connecting...

    Actually the computer is connected to the wifi but there is limited connectivity. I cannot go to any website

    Without any specifics as to your System Specs, Manufacturer Name = Dell, Manufacturer Model Name, Model Number and other identifying characteristics or the Wireless Card you are using Mfg. Name, Mfg Model, Mfg. Number, etc., it is difficult to add anything of value to your problem.
    I can say that in the past on some Dell Model wireless issues we've found that, evidently the driver (new versions) default to setting the "BSS Mode" to 802.11n and some have found that changing that setting to 802.11g has resolved their issues. So....

    This isn't well organised but I think this can give some information.
    I am not sure if its all relevant or not. I found this info in my ubuntu. If there is something missing please tell me how to get it in windows and I will put it here.

    Install the latest driver for your Intel Wireless adapter from here Support for the Intel® Centrino® Wireless-N 1000 give it a minute to completely load the information.
    When you connect your computer to the network using the Wired Realtek adapter do you have the same problem?

    Due to some reason wifi started working in window 7 for 1 day. I installed the latest driver as was suggested.

    Then the wifi itself was down for 1 day.

    Today wifi started and the problem came back. Not working in WIndows 7 but working in Ubuntu.

    I just use university's wifi. No wired connections.
