Hi,
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.
