I have got the WI-FI card Intel Centrino Wireless-N 2230 installed in my laptop Dell Inspiron 17R SE 7720.
Unfortunately this WI-FI card does not support 5GHz frequency.
I plan to buy Intel Centrino Wireless-N 6235 and replace by it the previous card in this laptop. The laptop has built two antennas (needed by Intel Centrino Wireless-N 2230).
Should it support Intel Centrino Wireless-N 6235?
From both product specification card sizes are almost identical. And basically the only difference I see is this functionality of supporting 5GHz networks (and because of it, support for the 802.11a standard).
Do you know are there any other requirements for Intel Centrino Wireless-N 6235?
I have tried to contact with Dell support, but they have not tested this card yet. As far as I know there are no BIOS restrictions for replacing WI-FI card in this laptop,
Thank you for help.
Thank you for your post Thom.
Note that Intel does not support the installation of wireless adapters in OEM systems. More info is available at http://www.intel.com/support/wireless/wlan/sb/CS-011644.htm.
Also there are many reasons that an adapter might fail completely or partially when installed in an OEM system. Take a look at http://www.intel.com/support/wireless/wlan/sb/CS-031167.htm.
The problem with this is that since these wireless adapters are designed to be installed only by the laptop manufacturer, there is no warranty or integration support on these products, it would be best to find out from Dell which 5GHz wireless card they can recommend. I they haven’t tested the 6230 they may have tested other 5GHz cards.
I bought the Centrino N-6235 as an upgrade for the Centrino 2230 in my Inspiron 17R SE.
Installing the card was a snap although I was briefly unsure how to connect the 2 antennas.
Windows 7 didn't detect the drivers right away for the card, so I had to download the Intel PROSet/Wireless Bluetooth Software for Windows 7 from the Intel Download Center.
Everything is working now, and I can connect to both 2.4GHz and 5GHz networks!
