Sometimes wireless phones will interfere with the signals. If the router or PC is anywhere near a phone, it might have a problem. I have one wireless network card that gives me fits like that. I have yet to get a PC working with it. I have other wireless cards that work fine. I also switched to 5GHz phones, which helped my old laptop. Check to make sure there's not a conflict with the encryption used by either the dell or the router.

SOURCE: no internet connectn for desktop but wireless works with laptop.

If your running xp, make sure the netowrk card is not disabled, make sure you rnot using a cross over cable. use the cable you got with the routers. Try reinstalling the network card, goto dell support andenter you model to get the drivers.

1 thing to check. goto start ,control panel.
double click on netowrk conections.
right click on the main conection witch is the card in your pc, goto properties. andin the list internet protocol (tcp/ip) click this. and pres properties.

make sure in here obtain ip addres is automatically. and obtain dns is auto too.

Try this let me know how you get on.

Make sure you've hooked up antenna properly, try to change it's position

SOURCE: will all wireless adapter brands and models work

If your talking about a wireless adapter that plugs in via a USB port then yes. If you are talking about a wireless network card that is installed into a PCI slot inside the computer, you can check with the network card manufacture for the specs but it should work as long as it is Windows compatible.
