The HP Pavilion dm1z comes with a Ralink RT5390 wireless card. At least this is what the unit I bought comes with, I'm assuming most if not all customers will get this one too, http://www.ralinktech.com/product.php?s=22
It is single channel 1x1 and supports up to 72Mbps as well as supporting 802.11b/g/n. It is not a dual channel card. It cannot connect to a 5Ghz WiFi network, only 2.4 GHz. I have a dual channel Cisco Linksys E4200 wireless router. I want to use WiFi n over 5GHz as this would be faster and offer less interference resulting in fewer lost or poor connections. But I cannot go 5GHz with the dm1z out of the box. It's unfortunate as 5GHz WiFi is becoming more common and will supplant 2.4 GHz eventually I'm sure. This does not impact my perception of the dm1z as I still like it a great deal and I do recommend it. For under $500 I know it cannot nail every feature I need now or may need/want in the future.
I found a fix the wifi issue on the HP DM1Z. HP released a Bios Update F.02 / F.13. This update was to add the Intel 6230 2.4 and 5GHz dual channel N plus bluetooth to the whitelist of adapters. I previously tried to add just a 6200 and it wouldn't work. I have confirmed that the 6230 works and gets 150-300mbps. Thank You HP!!!!!
