[NAME]  - You only need to disable the Qualcomm wireless adapter. 
I recently upgraded the wifi card in my Inspiron 5755 laptop to a Dell 1802.  The card in the 3455 AIO seems to be the same one in the 5755 laptop. The Dell 1802 card really improved my download and upload speeds.  I would like to do the same for the All In One but unlike practically everything I have ever searched, there was no video of this in Youtube.Is the 1802 the right card and if so, does anyone know of a resource that shows me how to replace it?
Can I upgrade the wifi card in my Inspiron 3455 AIO?
