    Hello

    I have 3 laptops, an ipod and an Xbox connected wirelessly to my router. I have no troubles with either of them but one laptop which runs really slow through wi-fi. I have been reading on people with similar examples and here are some stuff I noticed.

    1. The laptop is new and I ran it as a virus check with no viruses

    2. I did notice two wifi adapters as follows. Microsoft Virtual WiFi Miniport Adapter and Microsoft Virtual WiFi Miniport Adapter #2. They both show that they are working properly and I have checked for updates.

    3. My router is a Netgear DGN1000 modem/router. It is also updated on firmware.

    4. I have the right password etc.

    I do however have my xbox set up as DMZ and ports forwarded on the static IP for my xbox, in case it matters. This issue only occurs on our home network and it runs fine everywhere else so I am thinking that it could be a router set up issue.

    Thanks for the help

    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.

    Make sure you have the latest wireless driver from the laptop manufacturer's web site (don't rely on Windows to find it).

    How's the internet access if you connect by ethernet?

    Ok so a wired connection does work. Now I looked on the dell support page and couldnt find what driver I should download and update because there were 7 separate ones. I contacted them through the phone and they said they couldnt answer my question. I tried chat and waited for half an hour without anyone respondents. I tried again and I guess the chat is closed.

    Can you please tell me what driver I should download?

    http://www.dell.com/support/drivers/us/en/04/DriversHome/?c=us&l=en&s=bsd&cs=04

    The version for both of them are 6.1.7600.16385 and the driver date is 6/21/2006.

    Strange (to me) that they have no drivers. Maybe that means that you are supposed to use whatever Windows 7 finds after all. Use Device Manager to 'Update" the driver; if you already have the latest then uninstall it; reboot and let Windows discover the adapter and reinstall the driver (this is in case the installed instance is corrupted).

    When you mentioned the multiple files I guess you were referring to the ones for your model Dell; don't know why they have drivers listed there but not for your Service Tag. Anyhow the one there that you want to try is R311898.exe (because your adapter is the Intel(R) Centrino(R) Wireless-N 1030).

    Ok so I downloaded and installed the driver you mentioned and it is updated. I talked to dell customer service and they installed a spyware software which detected 142 threats. Now I currently have malwarebytes scanning the computer. I will update whenever possible
