A couple weeks ago, I got a new Lenovo laptop. When I ordered it (three months ago), Lenovo apparently didn’t have any WLAN (i.e., 5G or 4G cellular cards) in stock, so I couldn’t get one with a card preinstalled. But I got it with the harness (antennas and brackets and stuff) so that I could install it myself “easily”. I checked the Lenovo parts store, and they now listed two WLAN cards. I got the Quectel EM05-CN, because I know that has solid Linux support now. It’s a 4G card — I could have gotten the 5G card, but apparently the Linux support for that one is pretty iffy. It doesn’t really make that much difference, in my experience… (Whenever I mention having a laptop with built-in 4G, people without such a thing always defensively say “Oh, I just use a hotspot from my phone”. LIKE AN ANIMAL!?!?) Last week I got it and: Remove four screws, and pop the bottom off. There it is! Four antennas strapped down, and a place to pup the card in. It’s got four antennas — they’re for the 4X4…
