sorry my bad .. it isnt your wireless card, i misinterpreted your ipconfig comand.

 its your default gateway.

if you attach your router to your local area network connection, and then go to internet explorer. type http://192.168.1.254 you will get a screen come up and this is your router configuration page. on the left hand side look at mac address filtering. in here, add your wireless mac addreess; this is ( 00-19-7D-6F-FE-3B ) then save the settings. unplug your local area network connection and try again.  also can you supply me with the information of the make of your router and type ? send it me in a personal message if you do not want to have it made public.

my gguess would be someone has accessed your router and blocked you out. This would be why there is a password. To fix this, you will have to reset the router to factory settings . usually to do this you have to find the reset button and hold it down for about 15 seconds. the rest button will be about the size of a pen nib.

Hi James

I reset the modem back to default using both the reset button and also a utility provided by the ISP - still asks for a password and userid.

A further change. Yesterday I tried an external USB wifi adapter borrowed from a friend. When using the software that came with the adapter it would not connect. However, when I deleted the adapter utility (keeping the driver) and used XP to connect I managed to get a connection that lasted all day. This morning the adapter would not connect automatically however when I manually disconnected and re-connected again it established a link.

I have provided the ipconfig /all display below - anything obvious? Many thanks for the continued support.

right so now we willl have to manually configure the way you connect to your network. Make sure you have unplugged the external USB wifi adapter.

you need to make sure you are connecting using the windows utility, not the dell configuration or that one that came with the adaptor; to do this you go to network connections - control panel, then network connections. After this you will have to right click your wireless network connection (the one reguarding your WLAN card, then press properties. From here you should navigate your way to 'wireless networks' should be in the middle at the top. then make sure the 'Use windows to configure to my wireless network settings' has a check in the box. you may have to press apply.

After this, navigate once again to the 'wireless network connections properties', and click on the general section; top right. in here you will see a scroll bar. Scroll all the way to the bottom of this and right click 'Internet Protocol (TCP/IP)' then click properties. Inside here make sure the 'use the following IP address:' and  'Use the following DNS server addresses:'  are both checked. then enter the following information.

        IP Address:. . . . . . . . . . . . . .. : 192.168.1.5
        Subnet Mask: . . . . . . . . . . . .  : 255.255.255.0
        Default Gateway: . . . . . . . . . . : 192.168.1.1
        Prefferred DNS :. . . . . . . . . . . : 192.168.1.1
       

then click apply, or okay. you will then have to click apply at the ' wireless network connection properties' as well.

 If this does not work; you could try the default gateway as

     192.168.1.254

this sometimes works.

please feel free to contact me if you have any issues with this.

Sorry about the delay in reply - been away for a couple of days.

Tried as you suggest using the Dell WLAN card (after disabling the external adapter) but still no joy. When I make the changes the wifi link shows "connected" but cannot access the internet.

I am starting to think that there is a problem with the internal WLAN card as when I connect the external adapter (a TP Link TL-WN620G unit) all works ok.

I used XP to make the connection in both cases.

hmm it could possibly, try uninstalling the adapter. navigate to device manager start > control panel > System > hardware > device manager, in here locate your wlan network card, right click this and press properties.

Uninstall the driver from in here.

Restart your computer < very important

 and then go to the dell website and download the latest driver using your service tag.

 I hope this will fix your problem.

Tried as you suggest but results still the same. The computer waits while it attempts to obtain an IP address and then goes to "limited or no connectivity". I uninstalled the Dell WLAN adapter, rebooted and then installed the latest Dell driver.

When I re-installed the TP Link adapter it connects with no problem so I guess I will just stay with this solution and live with an external adapter. Hate to let it beat me though.....!
