Lenovo doesn't offer 5GHz WiFi card for x120e?

Prior I had mentioned that "Lenovo offers Thinkpad x120e option for 2.4GHz/5GHz 2x2 a/b/g/n wireless LAN adapter for $20".

But this option is now gone?!? I just checked the Lenovo site today and it is not there.

I think Lenovo has been tweaking their x120e offerings and the site now shows just three configurations. You can somewhat customize each one but none of them offer the 5GHz WiFi upgrade option that I saw prior.

The Lenovo tech specs PDF document for the x120 show this:

WLAN (for x120e)

• ThinkPad AGN (Broadcom) 2x2 AGN
• ThinkPad BGN (Realtek® - Stockton) 1x1 GN

I assume the x120e supports a 5GHz wireless LAN adapter as a 2x2 card is listed. But what's offered on the Lenovo site now is only "Integrated WiFi wireless LAN adapters: ThinkPad b/g/n". I'm guessing that's the 1x1 Realtek and not the dual channel Broadcom card.

HP is not offering a 5GHz option for the dm1z at this time on their site. The HP Pavilion dm1 Notebook PC Maintenance and Service Guide on page 18 notes these two adapters:

WLAN module (for dm1z)

• Broadcom 4313 802.11b/g/n 1x1 WiFi and 2070 Bluetooth 2.1+EDR Combo adapter - (BT3.0+HS ready)
• Ralink RT5390 802.11b/g/n 1x1 WiFi and BC8 Bluetooth 3.0+HS Combo adaptor - Rashi2

These are both 1x1. It appears there are no officially supported 2x2 modules for the dm1z yet.

Offering a 5GHz upgrade was one real differentiating factor for the x120e over the dm1z if you ask me. The x120e lists a 2x2 option so the unit supports one, this is better than the dm1z which lacks any official support for a 2x2 card currently.

I guess it doesn't matter if the x120e supports 5GHz or not since you can't get an x120e with one installed. An advantage the x120e had over the dm1z currently does not apply it seems.
