Vista connects to WLAN, XP does not

Hello everyone,

I am having a peculiar problem that I spent more time on than I should have. I am sure you guys can solve it fast

THE PROBLEM: I set up a wired/wireless network on my DSL line using NETGEAR RangeMax WPN 824v2. All wired connections for both Vista and XP computers around the house work. Also, Vista works over wireless as well. The three computers that have XP do not work on wireless. All find the network, take a long time to connect and then display the notorious "Limited or No Connectivity".

To throw a monkeywrench into this situation, my roomate has an XP computer as well, but he can wirelessly connect, only my XP computers cannot.

WHAT I TRIED (on XP machines):

1. The only thing I can think of that makes my XP computers different from my Vista machine and roomate's computer is Avast Antivirus. I read in other forums that that can be a problem. I turned off (but never uninstalled) Avast, but that did not change anything.

2. "netsh int ip"; "Netsh winsock reset" reset did not improve the situation.

3.ipconfig /all; /release etc did not change anything. timeout would occur and i would get the ip address starting with 192 or 198 (whichever means the connection to router did not work. sorry been reading too many forums -- forgot which one is which)

4. ran WinsockXPFix.exe to no avail

5. Turned off, disabled, repaired the wireless adapter in XP.

6. Reset the router, modem. Vista connected wirelessly right away, XP still shows limited connectivity.

Your thoughts would be appreciated. If there are some settings that I should compare between mine and my roomates XP, please let me know. I looked, but might have missed something.

Just one idea.

Google this -> VISTA BROADCAST FLAG

Disable that and hope that was it. Reboot that router after that.

I won't duplicate the content in our forum sticky with every member's post so be sure you've covered that. There are also those that install firewalls, norton and such and lock their wifi up solid. I didn't see where that could be an issue here (no comments about these in your post.)

As a test, take one of your XP machines to a wifi hotspot. Do they work there?

Bob,

Thank you for writing.

I don't have any firewall software on any of the computers, except the Windows Firewall. I diengaged it on XP computers but it did not change any of the methods.

All XP laptops are able to connect to other wireless networks, just not the one at home.

I read up on Vista's broadcasting flag and it seems to me that it should be turned off when Vista is having trouble with wireless connections. My Vista machine is working well.

Feel free to keep researching.

It also knocks other than Vista machines off the wifi.

Good luck!

Problem solved!

Bob,

Thank you for all your help. I finally found a solution that worked for me. For some unknown reason, the WEP key was different in the connection properties (on all 3 computers!).

Here is how I solved it: Control Panel > Network Connection > Right Click Wireless Network Connection > Properties > Wireless Network tab > Select the connection giving you trouble > Properties > Retype the network key.

I am wondering if some software caused this to happen?

We cover this in our forum sticky.

Remember I no long duplicate that with each posting. The forum sticky also tells that WEP is dead. It's something like 2 minutes to connect to a WEP (protected?) network.

Why would we use WEP today?
