d600 can see network, can't connect

My laptop is identifying my home network, and says the signal is strong, but
also says I have "limited or no connectivity." (Or language close to that.)
Until recently, I was having no problems connecting. It saw the network, I
put in the WEP, and that was that. I did update the laptop with a service
pack (if that's the phrase), which seems to coincide with the problem.

I got advice elsewhere on this forum to try turning on the Extensible
Authentication Protocol Service and the Network Access Protection Agent, but
I don't know where to find these.

Is this the only PC on the wireless? If so, try turning off security
on the router and your PC. If you connect fine, then you know the
basic hardware is good, radio and all. Then reapply the WEP or better
yet WPA or WPA2. WEP is relatively unsecure.

"Signal is strong" just means your close to the antenna of the router.
"limited connectivity" probably means you didn't get past the security.

Hi
From the weakest to the strongest, Wireless security capacity is.
No Security
MAC______(Band Aid if nothing else is available).
WEP64____(Easy, to "Break" by knowledgeable people).
WEP128___(A little Harder, but "Hackable" too).
WPA-PSK__(Very Hard to Break).
WPA-AES__(Not functionally Breakable)
WPA2____ (Not functionally Breakable).
Note 1: WPA-AES the the current entry level rendition of WPA2.
Note 2: If you use WinXP and did not updated it you would have to download
the WPA2 patch from Microsoft. http://support.microsoft.com/kb/893357
The documentation of your Wireless devices (Wireless Router, and Wireless
Computer's Card) should state the type of security that is available with
your Wireless hardware.
All devices MUST be set to the same security level using the same pass
phrase.
Therefore the security must be set according what ever is the best possible
of one of the Wireless devices.
I.e. even if most of your system might be capable to be configured to the
max. with WPA2, but one device is only capable to be configured to max . of
WEP, to whole system must be configured to WEP.
If you need more good security and one device (like a Wireless card that can
do WEP only) is holding better security for the whole Network, replace the
device with a better one.

Okay, I'll try that. What does a Macintosh's "WPA Personal" translate to, in
Windows-ese? That appears to be the security setting I have. (Still working
on this ...)

I think its PSK. Google that phrase "wpa personal".
EZLan is a good website for wireless info.

It's not Windows-specific terminology. When you use WPA (or WPA2) the
wifi adapter in your computer needs a "key" to decrypt ("unlock") the
the encrypted messages sent from the router (and to lock/encrypt
messages sent the other way). In a corporate environment, this key is
usually obtained by your computer ("shared") from a special server that
is part of the corporate IT system. In a home (or "personal") system,
the key must be stored ("pre-shared") in your computer. Thus,
WPA-Personal = WPA with a pre-shared key = WPA-PSK.
