Quick Question about wireless card

My e1505 laptop currently has the intel pro wirless 3945abg card. And for the past few weeks, ive been hit with the Problems Apply Profile that seems to be a common problem from google searches and i have tried everything i can from disabling DEP to a fresh windows install using both service pack 2 and 3 as well as the lastest intel drivers and im still getting the profile error. Therefore, i am thinking of upgrading my wireless card since maybe the card is getting old and dying. I want to upgrade to an Intel 4965AGN card. However, the only issue i might have later is based on the pictures, the 4965 card:


Where do the connect the antenna wires, i assume it is 1 and 2 and i leave 3 alone? I know its a stupid newbie question, but my older 3945 card only had 2 connection for it so it was simpler

 

Yes, use "1" and "2". "3" is added for MIMO but you won't be able to use MIMO unless you add a third antenna. Your "N" speeds may not be up to par with only 2 antennas though.

 

i dont use N networks. Only networks i use is B and G


any way add the Mimo?

 

Actually, I connected it to 1 and 3 as the middle one is supposed to be for the grey cord that is not included with the 1330 ):. However, you can connect them anyway you want and see what happens; I am sure it will not damage anything. Also, try seeing if there is a third wire somewhere in there as the n designation is supposed to work best with 3, if at all possible.

 

I'm hoping someone answer this question too cause I'm in the same situation i want to upgrade my card but don't know how to, also what is the best option for wireless n
