    Hi, i have a dell laptop inspiron 1545.
    I am currently having problems with the wireless connection, i can connect with the ethernet cable but not wirelessly, other laptops will connect as well as game consoles but not my laptop.
    I am currently using bt broadband, i also have problems with the connection as the laptop will automatically connect to other networks such as btfon and btopenzone. I have tried all the basics of re-setting the home hub, as well as trying to sort out the connection through the control panel on the laptop, but still have no luck with a connection wirelessly.
    any help will be much appreciated.

    here is the main details of my laptop
    OS Version: Microsoft® Windows Vista™ Home Basic , Service Pack 2, 32 bit
    Processor: Intel(R) Celeron(R) CPU 900 @ 2.20GHz, x64 Family 6 Model 23 Stepping 10
    Antivirus: ESET Smart Security 4.2, Updated and Enabled

    Fix #1:

    Try Removing Wireless Profiles and reconnecting.

    ------------------------------------------------------------------------------------------------

    Fix #2:

    TCP/IP stack repair options for use with Vista or Windows 7

    Start, All Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

    In the command prompt window that opens, type the following commands, each followed by the Enter key:

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset IPv4 TCP/IP stack to installation defaults: netsh int ipv4 reset reset.log

    Reset IPv6 TCP/IP stack to installation defaults: netsh int ipv6 reset reset.log

    Reboot the machine.

    ----------------------------------------------------------------------------------------------

    Also, are you able to connect wirelessly in Safe Mode With Networking?

    How to Access Safe Mode With Networking

    While the computer is turning on, tap F8 once every second until a black screen with white text appears. Using your arrow keys highlight the option Safe Mode With Networking and hit Enter.

    Note: If you're using Windows XP, connect to your modem or router with an Ethernet cable, then follow these directions.

    Click Start, and in the search bar type: devmgmt.msc

    Expand the Network Adapters section so that all installed hardware is listed.

    Take a screenshot of this window and post it in your next response.

    To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file. To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here.

    Disable encryption and MAC Address filtering on the router and try to connect. If successful you can probably re-enable encryption and reconnect.

    If by cannot connect you mean you can't see the wireless network, then make sure your wireless device doesn't have a hardware switch turned off.

    Also if you are trying to use the Windows wireless connection, then you will need to disable the Dell Wireless Utility as they will conflict and the Dell software will supercede the windows one.

    well i can see a the wireless network, but if i remove the ethernet cable i will lose all ability to come online, so no methods have yet worked, could it be possible that a virus could have affected the ability to connect as i used to have norton 360. i was later told to avoid norton and go for other companies as norton are more targeted.

    (terrynet) How do i disable the encryption and mac filtering on the router.

    I won't advise for or against Norton products, but to be sure that it is completely gone run the Symantec Norton Removal Tool.

    Using an ethernet connection login to the router, navigate to the wireless section and set the encryption (or maybe "security") to none or off or disabled. MAC Address filtering (or MAC Address control) may be in the same section or maybe in a "filtering" or "security" or "access" section.
