New Aspire One XP home won't connect with WPA2-AES

MemberMy mother has a brand new Aspire One D150-1920 (XP Home SP3 fully updated) and I am trying to help her get the wireless working from 120 miles away.
She has a DLink DIR-655 Draft N router that is identical to mine, down to the security key. When visiting, my ThinkPad Vista laptop connects instantly.
She also has a TIVO with their Wireless G adapter that connects fine with WPA2.
The Acer sees her wireless network and after supplying the WPA2 key, says it is connected and 'acquiring IP address'. When I remotely monitor her router, I can see the MAC address for the Acer connecting, but the IP address is 0.0.0.0. The Acer entry will then disappear, then reappear, in a cycle that continues until you disconnect the wireless.
When she plugs a CAT5 cable to the Acer I can connect to it using Crossloop and all of the settings look OK, including the WPA2-AES option and the key.
Acer email support said to remove all security settings on the router, and when I did that it connects fine.
There does not appear to be a newer driver for the Broadcom 802.11g wireless.
I am stumped and I will NOT allow her to run WPA when WPA2 appears to be supported.
I am stumped.
Any suggestions would be appreciated.

MemberMight be a 4315. The only place I see anything with a similar number is in the Device Manager for the Broadcom wireless under Details.
One entry is the "Device Instance ID" which is
PCI\VEN_14E4&DEV_4315&SUBSYS_E018105B&REV_01\4&192AC53F&0&00E0And under Hardware ID
PCI\VEN_14E4&DEV_4315&SUBSYS_E018105B&REV_01
PCI\VEN_14E4&DEV_4315&SUBSYS_E018105B
PCI\VEN_14E4&DEV_4315&CC_028000
PCI\VEN_14E4&DEV_4315&CC_0280Is the 4315 what you need to know?

MemberIn the wireless settings window, The Network Authentication is WPA2-PSK and the Data Encryption is AES.
Is there any definitive documentation as to whether or not this unit will support WPA2-PSK? I find it hard to believe a newer device that supports wireless would not.

ModeratorIf you have the atheros wireless (check square FCC sticker of bottom) it should be an AR5006/5007 wireless card.
The tech brief on the card does not specifically mention WPA2, but does mention WPA and AES. Although, not in the same sentence.
http://www.atheros.com/pt/bulletins/AR5007EGBulletin.pdf
I googled AR5007EG & WPA2 and it appears a lot of people have issues with it as well.
I would recommend WPA/2 with TKIP if the router supports it. Also try updating the drivers on the aspire one using windows updates. Also don't rule out a firmware update on the router as that can sometimes help.

MemberI will have her check the FCC tag later today.
Looking at the DLink wireless setup, it appears I can keep 'WPA2 only' as the WPA mode, with a sub option of "TKIP and AES' for cipher type. It is set for AES only now.
I will try that option and see what happens.

MemberIt is a broadcom chip. The tag says "Transmitted Module" BCM94312MCG. That matched the module ID I saw yesterday in Device Manager for the wireless adapter.
We did several tests.
DLink WPA2-PSK only AES / Acer WPA2 AES = connects but fails to get IP address.
DLink WPA2-PSK only TKIP & AES / Acer WPA2 TKIP = connects but fails to get IP address.
DLink AUTO WPA or WPA2 TKIP & AES / Acer WPA TKIP = connects but fails to get IP address.
DLink WEP 128bit / ACER Shared WEP = Connects and gets IP address.
I am disappointed that the Acer will only connect with the older less secure WEP.
The router is updated with the latest firmware.
I am curious as to why the tag says 4312 but the Device manager datails that I posted yesterday refer to a 4315.

Moderatordid some more digging. looks like the 4312 is the chipset, and the 4315 may be a stripped down version that only supports B&G where the product brief states the 4312 supports A, B, & G. no info, but maybe wpa2 was also taken out.
http://www.broadcom.com/collateral/pb/4312-PB00-R.pdf
the latest driver for xp i can find is 4.170.75 for the broadcom 4312 cards. the 4315 is basically the same, but
make sure you have this driver.
Also maybe perhaps 2 solutions
look into downloading the Broadcom Wireless LAN User Interface utility. latest is 7.20B that I can make out, but that is for vista. although may still work for xp. just google, and you can find it. it takes over for the wireless zero config and gives you many more options for connecting to networks.
also look into installing Acer eNet management from acer. latest ver should be around 3.6, once again for vista but it still might work. this utility gives you more control over the network card, and this may help support wpa2-aes
if that does not work, let me know.

MemberTime for glasses...
When I had gone to the Acer driver download area earlier, I completely missed the scroll bar on the driver tab, so I never saw the section for wireless driver updates.
I just grabbed the latest which is the 4.170.75 and now it connects fine with WPA2 and AES.
Thank you for pointing me back to where I needed to be looking.
