unable to assign network adress to wireless desktop

[zsir]

I have a wireless network that worked fine until today.....
my desktop is hardwired to a wireless router....my laptop and the kids desktop use wireless cards to acess the router.....all the computers work fine except the kids desktop...it can't acess the internet.... the signal strength is very strong it conects to the network but says

" limited or no access the problem occured because the network did not assign a network adress to the computer"

the network is secured and the correct wep key is entered.. I don't know whats wrong...The kids desktop is able to conect to my neighbors unsecured network and acess the internet.....it's been working fine for weeks and all of a sudden this happens...

help... I don't know what to try next..
thanks

I had something like this happen to me. The one thing that worked was to turn off the router for a while. Then turn it back on. It seemed to reset and it then assigned an address to the wireless computer again and all was fine. worth a try if you haven't done so already.

Hey, my first post here, I work in a networking call center, I'm far from being an expert, but usually we have found this to be a problem with Service Pack 2 for XP, and you can download a patch for it from MS, KB884020, and if that didnt work , to follow instructions for Limited or No Connectivity from pchell.com

If the above advise did not help!

Not having a Strong Signal is Bad. However having a Strong Signal is not necessarily Good.

The general signal showed by the Wireless Utilities and WZC (as provided by our Marketing friends) is actually = 802.11x signal + Phone + Microwaves + Brain Anxiety Emissions (j/k), in other words it is a visual representation of all the 2.4GHz in the atmosphere around the Wireless Client.

The real measure of Wireless signal capacity is Signal to Noise Ratio (SNR), a measure that takes into consideration the relevant Signal adjusted to the Noise Level. Wireless Pros use for hardware placement determination Gizmos (or software) that gives them a reading of the SNR.

So start with the Wireless Client sitting near the Wireless source and take it form there.

I know about how weird it is to get the neighbors but not your own. In my case it was clearly that the dhcp servere on the router wasn't working properly. It would be fine for other computers on my network. At first I thought it was the wireless part but then I noticed that, using netbuei as my file transfer protocol (as lots of people recommend on this forum) I was able to transfer files between computers on my network to and from the computer that wasn't recognized on tcp/ip. So it had to be an addressing problem. Then I tried accessing the dhcp server info on my router (a linksys). It wasn't assigning anything to my lonely computer that wasn't recognized. So then I just turned everything off for a good period of time, say 10 minutes. Then I turned on everything and it worked and the router's dhcp server worked just fine. Go figure. But if you want to discover if it's your wireless vs your dhcp server part of the router, just set your file sharing protocol to netbuei as is described on the ezlan.net website, and see if you can transfer files. If you can then forget about it being a wireless problem. It isn't. It's the dhcp and you can probably reset the router and get it to work one way or another (at least I hope so!).

Good luck.
