I don't use my computer much, and I'm very much a novice with upgrading components. But I'm looking to upgrade my WLAN card, so I can use the 5GHz band of my router. I just upgraded to dual SSDs, and I maxed out the memory on this thing years ago. Its still very fast by my standards, so I see no reason to get rid of it. From what I've read, upgrading WLAN cards isn't as easy as storage. Some manufacturer's only allow specific models/brands? Can anyone recommend a good card that works for the N73JQ?
