I have an old Compaq presario laptop that runs Windows XP. Today I booted up, and finally got around to putting all my old pictures on an external hard drive.

wireless network validating identity problem xp-6

My router is set to WPA2, but I don't find that option on my old laptop. Your old laptop Wi Fi system apparently does not have the stuff to connect to your router.

WEP WPA WPA2 As the years went by, protocols changed.

Apparently this is a fairly common problem with XP, as there is a lot of discussion about this across the Internet.

I haven't found the right fix yet, and am trying to avoid reformatting, which I can do as a last resort.

I have two XP laptops at home that were both working fine for weeks with a new Cisco wireless router, then suddenly they both say "Limited or No Connectivity." Both of these laptops work fine with another wireless router.

Also, a third laptop in the house (Vista OS) works fine with the same router that won't work with the two XP laptops. Thank You Very Much, Educated Guess I'd suggest doing this first: 1. When I try to reconnect, it grinds away for 10-15 minutes, saying, "Validating Identity" then I get the "Limited or No Connectivity" message. This unit was recently reformatted, but I haven't run malwarebytes or adaware or anything to see if that would clear it up.

Go to Start - Control Panel - Network Connections 2. Let me know how that goes Obmute, thanks for your suggestion.

This can be entered as 5 or 13ascii character or 10 or 26 hexadecimal characters" HUH? I saw somewhere online that the network key could be a number on a sticker on my router. UPDATE: I found this, but still doesn't explain what I should do.

I entered those numbers too, but still the same results. I know how to get out of that, but how do I ultimately connect wireless.. "This means that if you enter the password as hexadecimal characters, you must type exactly 10 characters (5 bytes) for 40-bit key, or exactly 26 characters (13 bytes) for 104-bit key).

If you typed other number of characters than 10 or 26, or any character that is not a hexadecimal digit, this is interpreted as ascii string. So, valid length of the string in this case is either 5 or 13 charachers. You can probably set your router to also converse via WEP, but that is not recommended.

If this condition is not met, the string can't be accepted as a valid password. Perhaps you typed letter O instead if zero, or small L instead of 1 etc." Also, I see someone suggests that WPA2 could be the problem. Anyone who can see your signal could crack it in a very few minutes.
