Solved Trouble getting WPA to work on new wireless modem.

July 25, 2015 at 14:24:25
Specs: Windows XP, 768 MB
My ISP just sent me a new modem which includes wireless. I have a computer in my house which doesn't support the WPA2 standard of security so I've always used WPA for it. However, I'm having a problem with this modem.

It has four options for security mode (pictured below): Open, WEP, WPA/WPA2-PSK (TKIP/AES), and WPA2-PSK (AES).

I try putting it on WPA/WPA2-PSK but the computer that needs WPA security can't connect to it and sees it as a WPA2 secured network on my wireless networks list. I can't see any option to do WPA only and I find it hard to believe that a router wouldn't have a way to do WPA security.

Is there something I'm missing here?

I've already posted a message on the ISP's support forums but I have no idea when they'll get back to me so I decided to see if anyone here has any ideas.

✔ Best Answer
Do you know the make and model of the router you haver been given?

Also make etc. of your (XP?) computer; and make/model of your wifi adapter?

This extract from Netgear explains your situation:

Not all wireless adapters support WPA and WPA2. Furthermore, client software is required on the client. Windows XP and Windows 2000 with Service Pack 3 do include the client software that supports WPA and WPA2. Nevertheless, the wireless adapter hardware and driver must also support WPA and WPA2. Consult the product document for your wireless adapter and WPA and WPA2 client software for instructions on configuring WPA and WPA2 settings.

Is your wifi adapter built-in; and have you checked to see if there are any updates for its driver?

Also does your system "see" the new router; even if you can't connect to it? If so then have you checked the settings for wifi access in the router's wifi security section - as in are there any restrictions related to the mac addresses of computer seeking to connect (i.e. is mac filtering active)?

The modem is an Arris TG1672G.

The computer in question is a Dell Dimension 8100 which is running Windows XP Professional Service Pack 3.

The wireless card in the computer is an Inprocomm IPN2120.

Edit: Just saw the edit to your post with the quote from Netgear. That could be the problem but I still find it odd that there's no WPA only option on the modem.

Edit2: The computer can see the wireless network but can't connect to it, which has been the case anytime I've tried to connect it to a WPA2 network. I can confirm that MAC address filtering is not on and there don't seem to be any other restrictions since my other devices had no problem connecting.

See if this discussion helps:

and this one also

It too suggests driver update for your wifi adapter; and an update for XP is mentioned/linked... which find here:

If the worst case prevails... you may have to replace the wifi adapter...?

This is one possible source for the "latest"? driver for you wifi card:

It looks like a third-party site; so if/when download/install it... be careful to do it all manually (if possible) rather than automatically. And if possible check that nothing else is "pre-checked" for installation... If there is note what it is and if it ain't specific to the driver - uncheck it (don't allow it to go in).

Not having used the site I've linked here I can't vouch for it. Equally you might also let windows search for the latest wifi adapter driver - via Device Manager etc ?

And you might also check on the Dell support area too for whatever drivers they may still have there?

I note that Dell say there is no XP support...? Did this Dell arrive with '98(SE) installed and you upgraded to XP?

Yes, this computer came with either 98 or ME (not entirely sure which as I wasn't the original owner and the sticker says it was designed for both) and I upgraded it to XP. Given this and the fact that my wireless card isn't built-in I feel like Dell drivers might be irrelevant.

EDIT: Trvlr, I tried to use the link you provided for wireless card drivers but when I got to the download page it said the file wasn't found. At this point I may just give up on this and use the external router I have rather than the wireless function on the modem.

Ah... If it's an add-in card... then likely easy to replace that card with one that has XP drivers of course..; and is more current with the latest encryption styles?

I'd also check the XP update mentioned earlier regardless?

My bedtime (I'm in the UK) but likely the Canadian/USA shift will click in shortly; and also one or two from just off Antarctica.

I checked the XP update and it told me my service pack is newer than the update so I didn't need it. It looks like the update is for service pack 2 and service pack 3 already includes that functionality.

This wireless card is probably just too old so I'll just have to replace it or use an external router as I mentioned in my edit to my last post.

Thanks for all your help though.
