On my dell E1505 laptop i have a intel pro wireless 3945 card and it's not working right and i want to repace it with the same card..I noticed that the model number of my 3945 card is WM3945ABG and when i go on the internet to order the same card  i see that the model number is WM3945AGM1GEN.. is this the same 3945 card and will it work on my E1505 ?
