    Recently, I've been noticing that my laptop is not recieving alot of signal from my netgear wireless router. I cannot view webpages in any browsers, yet in other programs the internet works fine and I can use other internet programs (furcadia, maplestory etc.) just fine without interruption. I have to restart in order to restore full internet access to my computer.
    And now, this morning, I got kicked off as usual and when I tried to search for wireless networks, there were none in range. I know that there are at least two or three in the area, one being mine, and the other being my neighbor up one floor from me. So, I think it's my wireless card. I have an Intel PRO/Wireless 3945ABG card in my laptop, running Windows Vista Home Premium. I've had this computer for a month now, with no problems up until now. I've had the router for a few weeks with no problems either.

    I can do IPconfig for you guys, but I forgot how to save it from the command prompt. So, if someone tells me that, I'll be able to show how my internet's set up.

    Try downloading the latest drivers for the Intel card from the laptop maker, upgrade the firmware in the router, and change the channel in the router.

    All my drivers and firmware are updated.
    I've tried changing channels, and it keeps happening.
    I've tried flushing the DNS cache several times, and releasing as well. nothing seems to work.

    To try to determine which end is at fault, take the laptop to a location with a known working WiFi network. A neighborhood hotspot or a friend with wireless will do. See if the machine is able to connect there. Also, does this happen when you're right next to the router?

    Start, Run, CMD to open a command prompt:

    Type the following command:

    IPCONFIG /ALL

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

    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

    can I try connecting to my neighbor's router, upstairs? Or do I need to find something farther away? If so, I won't be able to test until next week. My college has wifi and classes start next week.

    But anyway, here's the results of the ipconfig.

    As long as you have permission from the neighbor, that will do fine. I just want to see that the machine will connect to a wireless connection.

    As a test, disable encryption on your router and see if you can connect properly then. If so, we'll work on why encryption is getting in the way.

    If I disable encryption on my router, I can't connect to it.

    eidt: I take that back. I had to set the encryption to none on my computer too, and I connect fine to it right now.

    bleakxdiary try the connection with this Unsecured network for a couple of days. If you are able to connect fine then use some security.
    And if after using security you have same problem again then check the firmware on the router. That should be the latest One. If it is latest then try to reflash the firmware
    That Should help :)

    OK, now that you can connect, encryption seems to be the issue.

    If you are using WEP encryption, use ONLY the HEX key option on both ends, do not use the passcode option. If possible, I'd use WPA or WPA2 security, must more secure.

    Please supply the following info, exact models of the equipment please.

    Make/model of the wireless router.
    Make/model of network card or wireless adapter.
    Make/model of your computer (motherboard if home-built).
    Version and patch level of Windows on all affected machines, i.e. XP-Home SP2.

    The model of the router is Netgear WGT624
    The card is the Intel PRO/Wireless 3945ABG
    My computer is a Dell Inspiron E1705, Windows Vista Home Premium. I don't know how to look up the patch level on it yet.
