Wireless -Limited or No connectivity

Wireless
Hi all - I'm hoping somebody out there has some thoughts on this. I have a dell D410 that belongs to our COO, well due to lots of issues, I rebuilt it from scratch, installed xp sp2, all the dell drivers etc and tried to connect to our internal wireless network. It won't connect, it won't even pull an IP address, just says limited or no connectivity. So, I brought in another ap, and hooked it up (not to the network initially) the laptop connected just fine pulled and ip and could get to the configuration page of the ap. Enabled wpa security on the ap (just like our inhouse ap) and still could connect and get to the configuration page. Put the new AP on the network, can't get out of house on it, dropping 60-80% of the packets - ok so maybe that is our network configuration. So, I took the laptop to a nice neutral place, a starbucks and tried to connect to their network. It would pull and ip (oddly it pulled a 172.xx.xx.xx ip) and I couldn't not surf. not sure what I did (tried way to much in the 1.5 hours I was there) and ony once did I actually pull the correct ip for their network (about half way thru all the testing) and never could repeat. I have installed the KB884020 patch, fixed the registry, tried repairing the tcpip stack and now I'm out of ideas. I am able to connect to a rogue ap that is unsecured near our building and surf the web off it - so I'm just confused about what is going on. I've even deleted all wireless configurations and let it find them again and I can connect to the one rogue ap again (and access the internet) but still not on the internal office one or the second one I brought in. So Help!!! Lirria

Thanks. We'll let you know when a new response is added.

Are you running a domain? Since you completely rebuilt the machine, could be a credential problem with the machine. I know my AD domain at home will not allow a rogue (not a member of the domain) to get an IP address.

    I know this may sound silly, but sometimes when I've experienced something like that, I just deleted the Wireless Networks configuration and added the network configuration manually and it works like 100% of times, I've noticed that this happens when you have connected to a public "open" network or a "weak" encryption network, is just like the software can't handle the "new" advanced authentication/encryption and you just need to specify the configuration. Hope this can be useful Regards, Erick

    Sorry I didn't get back to you all sooner - it's been insane here. The laptop is not part of the domain, but the wireless is set up for vendors, consultants and the like to hook up to so we don't check for authenication. I actually deleted all the wireless configuration and added them back in same thing - It wouldn't bug me so much but he can't even connect to open networks (at least not reliably). Lirria

    I just wanted to say thanks for the suggestions on this issues. I finally wiped the hd for a second time and install XP SP1, and the issue went away. I have no idea what SP2 introduced that would cause an issue like this but after over a week of trying to get it to work I just made it identical to the one that was working and now it is just fine. Thought you all might like to know. Thanks again! Lirria

    It was a pleasure. So then there was no problem with SP1 it supossed to be the other way as far as I knew SP1 has a limited support for WPA.

    I know - I didn't think there would be a problem either, but it's something with sp2, dlink and the intel 2915abg card that just doesn't work, and since the COO really wanted his laptop back, I couldn't spend the time to troubleshoot the problem. Most likely it's rev levels on the firmware on the dlink and the intel card (at least that's my best guess). thanks again! Lirria
