Replace Intel Pro/Wireless 3945ABG with Intel Centrino Ultimate-N 6300

I have a Toshiba Satellite u405-s2826 laptop with an Intel Core 2 Duo processor (1.83 GHz, 2MB L2, 667 MHz FSB) and Mobile Intel GM965 Express Chipset with Intel Pro/Wireless 3945ABG. I'm looking to upgrade the wireless adapter and was thinking about the Intel Centrino Ultimate-N 6300 but I understand that the 6300 has support for AMT 6.0.

I was wondering whether this wireless adapter will work with my current laptop and I will have all the features (if not, do I need to upgrade my chipset or is there a wireless-n adapter that will work, such as the 5300). Just let me know if you need anymore information. Thanks for your help in adavance.

 

big chance you have a full-size card mini-pcie slot, afaik there's no full-size card Intel 6300, cmiiw
Check your slot to make sure, if it's fullsize, then the option is to get full-size 5300

 

Or you can get this:

bracket of Intel Centrino Advanced-N+ WiMAX 6250 to pci - eBay (item 140423226518 end time Aug-01-10 09:54:35 PDT)

 

nice one,,, a bit expensive but get the job done

 

you will also be short on antennas if you get a 6300. so you not only need the bracket, you'll also need to install another antenna
