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). If you use the 6235, then you will need to adjust the steps in this guide to use the appropriate drivers. The rest of this guide assumes you are upgrading to the 6230. A few have upgraded to the 6235 and report it as working. Many users (including myself) upgraded to the 6230 and can verify that it does work. However I think that either card would work. 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). The 6235 adds support for the latest low-energy Bluetooth 4.0 spec.

The Intel 62 are nearly identical, both are wireless plus Bluetooth adapters. As of, you can get an Intel Centrino Advanced-N 6230 wireless/bluetooth adapter on EBAY for $18 delivered. The very first step in the upgrade is to buy a new wireless/bluetooth card. 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. 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. Still if you need or want to upgrade your wireless/bluetooth card, this thread will tell you how. The erratic wireless performance remains a problem and I found that WIDI maxs out the cpus and makes the system sluggish. īut I have to tell you, in the end I was disappointed with this upgrade.

My slate wireless had some problems - it sees a lot of duplicate acks, jitter and retransmitted blocks on speed and quality tests at. 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. 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.Ģ) the actual step by step guide for the upgrade (down loading drivers, removing old drivers, etc etc), andģ) another posting for optionally installing WiDi (Intel® Wireless Display).
