This site has lots of good info on upgrading the ASUS EP121 Slate's wireless/Bluetooth card to an Intel® 6230, but I could not find a beginning-to-end step-by-step guide - so I made this one. I will break this guide into 3 postings: 1) this introduction, 2) the actual step by step guide for the upgrade (down loading drivers, removing old drivers, etc etc), and 3) another posting for optionally installing WiDi (Intel® Wireless Display). I upgraded my wireless card because I was seeing erotic (opps, I mean erratic) wireless performance and I was curious to try WIDI and it was cheap. My slate wireless had some problems - it sees a lot of duplicate acks, jitter and retransmitted blocks on speed and quality tests at myspeed.visualware.com . But I have to tell you, in the end I was disappointed with this upgrade. The erratic wireless performance remains a problem and I found that WIDI maxs out the cpus and makes the system sluggish [more on that later]. Still if you need or want to upgrade your wireless/bluetooth card, this thread will tell you how. I did this under Win7. The original wireless card in my slate was the Qualcomm Atheros AR9002WB-1NG adapter, which is Single band (2.4 GHz) with a max of 150 Mbps. I replaced it with the Intel Centrino Advanced-N 6230 adapter, which is Dual band (2.4GHz and 5 GHz) with a max of 300 Mbps. [Hardware ref: http://www.qca.qualcomm.com/media/product/product_75_file1.pdf and http://www.intel.com/content/www/us/en/processors/centrino/centrino-advanced-n-6230-brief.html ] The very first step in the upgrade is to buy a new wireless/bluetooth card. As of 9/3/2012, you can get an Intel Centrino Advanced-N 6230 wireless/bluetooth adapter on EBAY for $18 delivered. The Intel 6230 and 6235 are nearly identical, both are wireless plus Bluetooth adapters. The 6235 adds support for the latest low-energy Bluetooth 4.0 spec. The 6230 is a bit cheaper and currently appears to use more stable drivers (the v14 drivers) while the 6235 requires the v15 drivers and there are some postings suggesting that users are having trouble with the v15 drivers (more on this later). However I think that either card would work. Many users (including myself) upgraded to the 6230 and can verify that it does work. A few have upgraded to the 6235 and report it as working. The rest of this guide assumes you are upgrading to the 6230. If you use the 6235, then you will need to adjust the steps in this guide to use the appropriate drivers. The 6300 series is not suitable for the EP121 - while it is capable of 450 Mbps wireless, it does not have Bluetooth - also it uses 3 antennas (the Slate has only 2). Note that these Intel wireless adapters are incompatible with some of the early 'pre-N' release routers. If you have such a router, you may need to get a newer certified N level router. Be sure to download new drivers before swapping out the card! And be sure to uninstall the old drivers before installing the new card (read my next posting for details on these steps). There is a very helpful video by user "Malfunkshen" that shows all the physical steps needed for the upgrade: from opening the EP121 case thru replacing the wireless card and closing the case. It only takes about 8 minutes. It does not show the necessary software steps - but this thread will cover that.

Below is a picture of my old Atheros card and my new Intel 6230 installed in my slate. Note how I had to bend the Main 1 antenna wire to fit.
