    Hope someone can help with this!

    I've recently got a new modem/router hub and when I try to connect to it wirelessly, it'll connect, but then my computer will drop the connection and won't get it back until I restart. I'm certain it's a computer problem and not a router or modem problem since my mother's netbook can connect and stay connected for hours. The router is in my living room and it doesn't matter where my computer is, whether it's in the living room too, or in my own room, the connection will still drop. When I open up "Connect to a network" in Vista, there are absolutely no networks in the list, even though I know there are plenty in my apartment block. The wifi switch is on, and the list only refreshes when I restart. The connection can drop at any time, whether it's 5 seconds after I've connected, or 30 minutes, but it does it a lot and it's becoming infuriating. I hope someone can help with this because it's driving me nuts already!

    Any advice will be very much appreciated and if there's any specs that need to be supplied, I can definitely do that.

    Thanks in advance!

    Nikki.

    Do you, or did you ever, have any non-Windows firewall or security suite on the machine? If so, which one?

    For when you have a connection and for when it has been lost ...

    Please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector and show ...

    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 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.

    As requested, here are the results from the ipconfig /all command. I'm not sure how to upload the screen print from the Xirrus program so if you could help with that, that'd be great too. Hope this helps and if you need anything else, please don't hesitate to let me know. Thank you in advance!

    Also, I did have Norton initially installed when I got the laptop but I removed it, then I had avast on it, and now I use Microsoft Security Essentials and AVG.

    Best to run the Norton Removal Tool, just in case it did not go away completely and cleanly.

    And for the same reason probably should run this Avast Uninstall Utility.

    If running those doesn't cure this I'd also get rid of AVG to see if it is acting up.

    Instructions for uploading screen shots are in this library article. (However, you may be restricted from uploads until 5 or 10 posts.)

    What did the Xirrus show? No networks in agreement with what you reported in your initial post? If so, no need to show it.

    Okay, if that works, it's the screen print of the Xirrus stuff. Have a look at it and tell me what you think. I'm completely new to this program so I'm not sure if it's entirely relevant. In the meantime, I'll remove all the antivirus stuff, but I don't know why this problem has started now, when it was working fine a few weeks ago, and I haven't changed my AV since last year. Again, thanks for your help in this. It's truly appreciated!

    That's the monitor, which doesn't show us as much information as the Inspector, but it is showing wireless networks (which is the main thing I wanted to know). Is one of those yours? Was the shot from when Vista was saying no networks available?

    Sometimes a security application gets corrupted and can do all kinds of random things. A few products can make wireless networks "disappear." Norton and ZoneAlarm have been known to "rise from the dead" months or years after being uninstalled and drive people crazy.

    From your initial post I think that your wireless adapter is failing. However, it could be some kind of software problem and I want to explore any of those possibilities we can think of before giving up on the adapter. Nonetheless, if you have an external card, maybe a USB one), or can borrow one you could also be testing with that to see if it behaves better.

    Okay, the first one is of my "Connect to a network" window, in which you can see that Vista isn't picking up any wifi connections whatsoever, protected or unprotected. The second one is of the Xirrus, which also shows no connections in the panel.

    I got rid of all the AV software except Microsoft Security Essentials and I've only just restarted after the full uninstalls so I'm not sure if it worked or not. I guess we'll find out if and when my connection dies! Will keep you updated with the situation in the morning, since it's almost 2am here, but once again, thanks for all your help and any input in regards to these screen shots is very much appreciated!

    From the first screen shot I provided you with, the connection highlighted in yellow is my connection, so at least the Xirrus program is picking it up, but like I said above, it's not picking up any connections when the wifi dies completely. I'm at a loss here. I don't have another wifi card, and at this point in time I probably couldn't afford to buy one. Any other options that won't break the bank? Thanks again, and I apologise for replying twice, haha.

    I'll keep my fingers crossed that it is/was that software you've uninstalled and cleaned up, but really do suspect it's the adapter.

    After reviewing the thread again ...

    Make sure you have the latest wireless driver.

    Try your adapter with your mother's netbook (disable or switch off its integrated wireless while testing).

    I updated everything yesterday re: wireless drivers.

    I've been online for almost an hour now, and while the connection does drop occasionally, the list of networks I can join doesn't disappear. I sometimes get the message "The wireless network security key is not correct." when I try to connect to my wifi network, but this can be remedied by removing the wireless profile via network connections. It's a tad annoying but a lot better than having to restart my computer all the time!

    I'm not entirely sure what I did to fix this, if it even is fixed, but I'll keep the thread updated over the next 48 hours to make sure this isn't just a fluke.

    Again, thanks for your help in this matter. I really appreciate it!

    Okay, scratch that last post. About ten minutes after I posted it, the wifi died and I didn't pick up any networks. Go figure that I think it's fixed when it's really not! Again, any ideas would be appreciated. Thanks a lot.

    The randomness, especially of the networks "disappearing," is an indication to me that the adapter is failing.

    I have no experience with it but think that this would be a decent adapter for a tight budget.

    You'll need to search for something good in your area.

    Update!

    So I installed Windows 7 on my computer a few nights ago but it didn't help the problem. The only way I can stop dropping the signal is if the router is physically right beside the computer. I've taken your advice and am going to go shopping for a wifi dongle today. I really hope this helps because I'm thinking the only other option is to replace the laptop completely or just stay in the one place, using the wired connection all the time. Once I get the new adapter, I'll update this page to let you know if it works. Thanks again for your help in this, it's appreciated as always!

    I sure hope the new adapter works! Remember that there will probably be a driver update available on the manufacturer's web site. It seems that the shipping driver (on the CD) always has bugs.
