Solved Old IBM Thinkpad R51 with XP Can't connect to home wifi

Specs: windowsxp professional, 1ghz? /512mb
Hi I have an old IBM Thinkpad R51 with windows xp on it and cant connect to my home wifi. It was sitting around and preparing it for sale on ebay(yes people buy these old machines) but at first before all the updates i had to do there was no way to enter a password. After all the updates i can do that now but the system is still not accepting it. I checked heaps of things but i suspect the only thing left that i cant find is wether the machine is discoverable. My home wifi shows up and other connections in my building(neighbours) but the only thing i can think to test it is to take it to a free wifi hotspot. Have little time to do so and i cant remember using wifi in the days when i had windows xp installed on my home desktop...so no experience with doing it. Got any suggestions?

PRO/Wireless 2200BG:
Uninstall the driver of the adapter:
Computer > properties > Device Manager > Network..> wireless adapter > properties > uninstall. Reboot and check if the driver is reinstalled correctly.

or install latest driver from Intel if not already installed:

Netgear router:
There is US firmware version for your router. Download from Netgear website.
If the router is an Asian model, check for compatibility first

One possibility, if it's an old laptop, is that it's WiFi adapter only recognises the old (and weak) WEP wireless encryption, but your wireless router may be configured to use WPA or WPA2 encryption.

WPA/WPA2 probably didn't even exist when that laptop was built.

Temporarily re-configure your router to use WEP encryption and see if that allows the Thinkpad to connect.

I have an olde (2005 vintage) Acer Aspire; still runs XP and connects to my much more recent router wifi OK - using WPA/WPA2.

What password are you referring to?

Does the laptop connect OK to the router/internet etc. via cat-5/ethernet cable?

After all the updates i can do that now but the system is still not accepting it. I checked heaps of things but i suspect the only thing left that i cant find is wether the machine is discoverable.

The laptop discoverable - where do you mean it to be discoverable?

Does the laptop have wifi adapter capability (rather obvious and basic I know - but then...)?

If you open a command window and type:

< ipconfig /all > (not the <>)

what do you see?

If I'm reading you correctly you can now enter your password but it doesn't accept it. A bit basic I know but are you absolutely certain it is 100% correct because paswords (pass phrase or key) are case sensitive?

Also see if your XP encryption is set the same as your router. It could, for example have been set to WPA in the past but your network is now set for WPA or WPA2.

Always pop back and let us know the outcome - thanks

Yes looking at laptop right now and it sees the router as having wpa2. The password for the router is what i am referring to. Yes ethernet works. I dont know how to explain the discoverable thing. I come across that sort of thing a lot with phones so thought it might be an issue. yes the laptop has wifi. Under 'choose a wireless network' it lists whatever connections are available...any connections in the area. Mine and many others.
Typed the command and It says 'Ethernet adapter wireless network connection 2: media state: Media disconnected. Description:Intel<R> PRO/Wireless 2200BG Network

Yes not accepting the password. Doesn't say any errors or anything. I have it exactly right and have other devices connected to the router so i know its right. The WPA thing is set right. Havent changed it. Trying WEP now to see if that works

Tried the wep thing and no success. I rebooted both machines to make sure it took before i re-enterred password. I also to make sure the password is right i typed it in a word document and pasted it...still no success. Might have to try it at a free wifi hotspot as really no other places to try.
Oops something is odd. I logged into the router and it shows it didnt change to wep. Trouble is the routers page is in japanese or chinese and i cant read it. I guessed when i thought i had made the change. Like clicking an OK button after selecting. Hmmmm. Have been trying to find out how to change the language of the router page but no success so far. This is the routers manual http://documentation.netgear.com/kw...

Oh thanks sluc that did it. I installed the latest driver from the website link you sent...well it seemed to not go well as it said some file was shared or something. So i waited for it to finish and went to the folder it downloaded to and reran it with the ethernet disconnected. I clicked on the setup file and it was a different look. It said something about getting rid of the old driver or software and i thought ok this sounds right. Anyway i am on the net with wifi yay!!! :0)
