    I have a HP laptop that runs windows Vista Premium, and is connected to an old Netgear wireless router, with which a broadband modem is connected to.

    I have had this setup for nearly two years, and has been running great, including this morning. However tonight I cannot get the laptop to connect to the internet. I have had a couple of weird issues before, but restarting the computer has always fixed it. This time I have restarted everything, and I can access other computers on the network (not wireless) but not the internet.

    Strangely, a hard drive that is connected to another computer that is shared for my backups is also not being found. (the other computer is plugged into the router through an ethernet cable, and internet works fine).

    MSN, Explorer and the like will not connect to the net. Interestingly, when I start Mozilla Firefox, which loads a simplified google homepage, after a long long time, loads about hald way.

    Does anyone have any ideas what the problem could be, I dont know what to do or try, because I havent seemed to change anything to stop it working. Any ideas I could try would be much appreciated.

    OK after some playing around it is still not working, however I have noticed under the network icon in the bottom right corner, it says connected 'local only' instead of the usual 'local and internet' I think it is.

    Does this give any sign as to what the problem is?

    Any help or advice on how I could help myself would be much appreciated.

    Olivier

    EDIT: Arggh, just went back to my laptop and it changed by itself back to 'local and internet', however I still cannot connect to the internet

    Are you connecting via ethernet or wireless? Can you connect the other way? If so, how does that work?

    Please try to connect both ethernet and wireless and show ...

    Start, Run, CMD, OK to open a command prompt:
    (For Vista type CMD in the Search box after Start)

    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.

    Thanks Terry,

    The problems I am having is connecting with wireless, however, when I grab an ethernet cable from another computer on the network as I am now, internet an all works fine.

    Here the results from the ipconfig... ( I did this while connected to ethernet and also had my wireless switched on. Hope this is OK???)

    That's fine output. It shows, as you said, a good ethernet connection. And it shows that the wireless adapter couldn't get an dynamic IP configuration from the router. Often this lack of communication is caused by an encryption mismatch (yes, even if you have been connecting OK for a day or month or couple years).

    My first suggestion is to disable encryption on the router and try to connect wireless again. Assuming success you should be able to re-enable encryption and reconnect.

    You should also delete any stored wireless profiles and start the connection from scratch.

    OK I have tried quite a few things as suggested, from starting the join wireless network again, to turning off encryption and pushing the reset button on the router which didnt seem to do much.

    I have also got another laptop that was previously working to connect to the network automatically and it still works fine after all the playing around I did with the router.

    But my laptop still wont connect. Is it possible that there is a hardware fault with my laptop?? Some advice on how I could verify this or do some more testing would be great. I think I will bring my laptop to uni and see if I can connect to the wireless there as I have been able to in the past.

    Thanks for the help thus far.

    Wow,

    This has puzzled me. Admittedly I havent tried to connect my laptop to the network for quite a few days, but im sure I tried after all the changed I was doing with the router etc.

    Im not sure maybe because I have restarted the computer since then or something, but I now it is working!!! :p

    I guess it may have been something to do with the encryption, but maybe it didnt kick in until I restarted or something, its couldnt just be a random problem as it wasnt working for quite a long time.

    Anyhow thankyou all very much for those that assisted me getting it working. :)
