Well I bit the bullet and replaced the Intel card, too. I do plan to hold on to the card as I do want WiDi but I also need a stable mobile WiFi. Went for the Broadcom. As such I'll watch this space. Until then keep the faith that intel is working tirelessly day in day out to solve the problem.
The how to is listed in my Blog at: http://macdonaldz.blog.com/2013/06/01/replace-intel-centrino-advanced-n-6235/
Good luck peps.
