TL:DR The Framework Laptop 16 Mediatek RZ616 WiFi card is just as janky/buggy as any midrange OEM WiFi card (even Intel). While it may be fast and low latency, if you want the same speed without any bugs/jankiness, I would probably recommend swapping in an Intel AX210 WiFi card.
I hate the MediaTek RZ616 chip and I haven’t even finished setting up the laptop. I’ve been demoing the laptop and 2 out of 2 times that I’ve closed the lid and let the laptop go to S0 sleep (Windows Modern Standby) it hibernates overnight (yay, that’s what I wanted to happen and I’m glad it seems to be following this) but then when it resumes from hibernation the next day the WiFi card takes like a whole minute for it to stop saying connected without internet. (Whether or not I let it be or I turn off WiFi and turn it back on.)
The issue that occurs has nothing to do with S0 sleep (as regularly resuming from S0, opening the lid, results in perfect operation.
The issue seems to be resuming from hibernation (and I would presume it would have the same issue with resuming from S3 sleep (if I were to enable it).
I especially believe this is an issue with this crappy WiFi cars because I’ve had this issue with 2 random ACXXXX model Intel WiFi cards that came preinstalled in 2 different desktop motherboards with included WiFi. After I replaced the WiFi card in the desktop that I still needed WiFi for (the other one I have hooked up to Ethernet and WiFi just for quick share and stuff) with an Intel AX210 I NEVER had any issue with resuming or anything.
Also, I will try to report back if I do order another AX210 for this Framework Laptop 16. (I may also try the BE200 in multiple AMD systems for the fun of it.)
