Wireless Cannot Connect with Security On

[Guest]

My Vista Home Premium will not connect wirelessly if I use any security
settings (WEP, WPA, WPA2), but it will connect normally if there is no
security (open). I can get other computers here running XP to connect just
fine with any security setting on the same router. And, the symptoms are
exactly the same using two different routers, a Linksys WRT54G and an older
D-Link 614+.

I frequently get an Unexpected Error if I try to put security settings in a
manual profile, or Parameter Incorrect if trying to do it through a change in
properties of an existing open connection. When I am able to get it to save
the settings, then the wireless never connects and times out.

The machine in question is a fairly new Dell notebook E1505 with an Intel
4965AGN adapter, and I spent 3 hours on tech support with them and they
couldn't figure it out.

I've tried the usual reloading drives and so on. I tried turning TCPIP 6
off, and the BROADCAST flag off, and put in a hotfix related to wireless DCHP
issues (forgot the number), all to no avail.

did you try the November drivers from the INTEL site?

Hi Barb,

Yes. First I tried the driver only (version 11.5.0.32), then I tried the
whole ProSet download (version 11.5.0.0) but neither fixed the connection
problems. They did seem to fix (or greatly reduced) the Unexpected Error and
Incorrect Parameter issues.

Then the Dell guy installed their own package with the same driver and
ProSet version as above. Now we are back to the Unexpected Error and
Incorrect Parameter for some reason, and still no connection with encryption.

Thanks
Bob

I'd uninstall the Dell pkg and go back to the generic Intel version
for starters.

The next thing I'd do is with the Linksys Router, change the SSID to
something new and setup WPA2 security with a new passphrase (use
something simple to start like testingwireless (you can change it
later to something stronger). Then setup the passphrase on the Vista
side. See if starting "over" has any impact.

I installed the Intel driver and changed the SSID as you described, but still
could not connect on WPA. It did get rid of the Unexpected Error and
Incorrect Parameter, though, so that is progress of a sort.

I let it "diagnose" the problem and it says "Wireless association failed due
to unknown reason."

 

[Barb Bowman]

please post the complete text output of

ipconfig /all

run from an elevated command prompt

Unfortunately the notebook is now not available to try this until about mid December. If it isn't fixed by then I'll post back. Thanks for the help.

My name is Inácio and I have the same problem with the Wifi conection.
I have a Asus P5K3 Deluxe/WiFi-AP motherboard with a Realtek RTL8187
Wireless 802.11g 54Mbps USB 2.0 Network Adapter onboard. My OS is Windows
Vista Home Premium X64.
I have already upgraded the drivers with Asus and Realtek driver package.
The error still remains PEAP: error loading module.
SecureW2 TTLS: unknow error
When I went to Event Viewer I saw the related message: Unable to find Point
to Point Protocol.
Where can I find it??

Kind regards

I'm also having the exact same problem with an HP laptop with Vista Premium.
I've tried everything. It just will not except any passphrase, complaining
its not 5-13 characters when it is. With WEP off, it connects. My XP laptops
can connect with the same passphrase. So what gives?

 

[Barb Bowman]

WEP is not safe or secure. Change to WPA2 or at least WPA. Does that
resolve your issue?

Please list everything you've tried and post the text output of

ipconfig /all

run from a cmd prompt

also please post info on the brand, model, hardware revision and
firmware version of the router you are using.

I've seen everyone saying they updated all the drivers on their machines,
Have you tried a firmware update on your router? If you are using an older
router, try turning off the IPv6 in windows under the TCPIP settings

 

[flybuddy]

OK, we finally have the notebook back to work with and below is output as you requested. By the way all the latest Vista updates have been installed.

were you attempting to connect to the wireless when you ran this
because it shows media disconnected and no IP?

I would not expect the 614 router to work, but if the Linksys is one
of the newer ones, it "should". I'd recommend trying the Linksys
setup with broadcast SSID ON, mixed b/g mode and WPA2 and I would
try channels 1, 6 and 11.
