My wireless card on my Dell D400 laptop has, from all I can tell, died. Even when everything is saying it is running I cannot see any networks while just days beforehand I could find mine and 2 neighbors' networks listed. The Original WiFi was a Broadcomm 4317 a/b/g mini-PCI card. I want to replace it with an Intel b/g/n model because Linux recognizes the Intel without having to download any drivers. Are these cards standard enough that I can just get one and plop it in, or do I have to check for motherboard compatibility, socket design or the like beforehand?
