I recently bought a Laptop with Vista and have been trying to connect it wirelessly to my existing XP network, When I try to connect to a network it sometimes finds other networks besides my own, but it has yet to find my network. I've tried turning off Norton on the main computer, and restarting the router, but none of this has worked. I also tried setting up a connection manually, with typing in the security information and SSID, but this has not worked either. Heres a few things I have heard about but have yet to try: 1. I've read that it could be something with DHCP Broadcast 2. Or that my router isn't configured for TCP Extensions for High Performance 3. Someone has also said that by downloading this installer http://go.microsoft.com/fwlink/?LinkID=70582 to my XP machines and rebooting them will fix the problem If anyone has the same problem or knows a sure way to fix this problem, Pleas don't hesitate to post. Thanks in advance fo your help!

Hi, Thank you for the post. Before we go further, I would like to confirm the following points with you: 1. Is it a non-broadcasting wireless network? 2. If it is the network topology of this environment: computers (including Windows Vista computer and two Windows XP computers) Wireless router Internet? 3. What is the exact wording of the error message when trying manually to connect the wireless router? Meanwhile, please refer to the following KB articles for troubleshooting wireless issue: How to connect to a wireless network in Windows Vistahttp://support.microsoft.com/kb/928429MSBBN: How to troubleshoot wireless connection problemshttp://support.microsoft.com/kb/831770 Hope it helps.

if the laptop is x64 and your xp system is 32 the vista machine will read the other computers run your netsetup file and put it on all computersonly thing to remember vista is usually 64 bit so xp WILL not read the laptop

I have the same problem as the originator of this post. Here are my answers: 1. Is it a non-broadcasting wireless network? No it is a private but broadcasting network. 2. If it is the network topology of this environment: computers (including Windows Vista computer and two Windows XP computers) Wireless router Internet? Topology is vista > wireless router > internet with a separate router for wired routing. There are7 xp computers (6 wired) and one Vista 64 bit. 3. What is the exact wording of the error message when trying manually to connect the wireless router? There is no error message but no other computers were originally visible. I have used the Link Layer Topology Discovery (LLTD) Responder (KB922120) on one of the xp computers from http://www.microsoft.com/downloads/details.aspx?FamilyID=4f01a31d-ee46-481e-ba11-37f485fa34ea&displaylang=en&Hash=BAGpJzxZD6dsNIGqr5z3inLZE3kDfc7LNsmHyKAxZXw3C4DhzzGXpfznNvXGc15YecsMOdlVBlacCIP%2byQqDTQ%3d%3d The LLTD responder installssuccessfullyand allows me to see anxp computer with service pack 2installed,but will not install on an xp computer with service pack 3. Attempts to connect to the network are unsuccessful in both cases. What do you recommend and thank you in advance for the help!

@ Randy: this thread 'died' immediately after the OP started it, in December 2007. He hasn't been heard from since.....As for your 32-bit/64-bit comments, and about netsetup:- so long as the basic networking is in place, and file & print sharing are enabled on the computers, it doesn't matter if computer A is running XP x86, computer B is running Vista x86, computer C is running Vista x64, and computer D is running XP x64: they will still talk to each other (and, in both directions.)- The 'netsetup disc' isn't required for Vista (FWIW, Vista doesn't have the Network Setup Wizard that XP did.) That was made to facilitate file & print sharing with machines older than XP (read: Win98/Me.)@ Whatawaste:- First, I'd like to say that your network topology is likely to bite you in the behind at some point (if it hasn't already.) Unless you specifically configured that wireless router to operate in AP-Only mode (and, rarely is this a single, intuitive setting), the NAT (network address translation) layer created by the second router will make sharing between the two networks (and, yes, it would be two separate networks) problematic at best, impossible at worst. I would highly recommend that you correct this situation, unless you mis-stated how you actually have things set up.If I read that right, it goes:modem > wired router <------------------->wireless router <----->Vista PC | XP PCs- As for LLTD: unfortunately, Microsoft didn't write the LLTD responder for XP SP3. As such, it won't install on SP3. (SP3 was supposed to include that, but it didn't make it into the final release.) You can find instructions on how to install it manually in this article.(For both you, and others reading this thread: in the future, install the LLTD Responder before installing SP3. It'll work fine that way.)- Workgroup name. Vista doesn't care about this nearly as much as XP did; however, to simplify things, the workgroup name on your Vista machine should match that of the XP boxen. You can view and change it (in Vista) in the Network and Sharing Center.HTH,Chris
