The physical connection between the wifi/bluetooth card of my laptop (Lenovo Yoga 710-14IKB) is unreliable. It manifests in blue screens with various error codes, usually shortly after waking from sleep, and sometimes, when I reboot after one of these crashes, I find that the wifi and bluetooth functionality has completely disappeared (no trace of it in Device Manager). Opening the laptop and re-seating the card has worked in the past to bring the functionality back, but eventually at some point it stops working again. So I need to look for a more reliable and long-lasting solution.

So, one obvious question is whether the problem is likely to be with the card (presumably replaceable) or with the motherboard (not so easily fixed). And has anyone got any other suggestions for dealing with this problem?
