I purchased that card and used it in my Latitude E5430, a very similar system to the E6430, and the card was both an easy install and works like a charm.
Hi all, I have an E6430 with an i7-3740QM processor that has a single-band WLAN card, a DW1540, and apparently no Bluetooth, either.  I was looking at an upgrade to an Intel 7260HMW Wireless card. Does anyone know if this will work and get me decent bluetooth to connect my audio to a UE Boom portable speaker, and ideally the benefits of a dual-band wifi? Thanks in advance for sharing any experience you may have with this.
