This or the note 8 Pro?
I have a Spigen case on my redmi note 7. I drop my phone a lot and this is the first case I've been happy with.
With wifi already switched on, lock screen comes on, wake the phone again, 5 mins, 10 mins (varies) wifi icon still shows connected, no wifi apps work afterwards, ie Firefox/Chrome will not connect to internet. It's also very random in time intervals and what it takes to get the wifi back working. Same on both of our phones recently received. BT/Plusnet standard Hub. Plenty of similar posts out there around the Globe with these, so maybe not the Hub, but who knows? No fix seems available from Xiaomi so far, so maybe a hardware issue? Our's are going back!
Has anyone tried the Spigen cases? They look pretty good but I'm wondering how they feel, are they hard and as a result, slippery? I'm looking for something with more protection than the free one but with a similar feel.
If both are having issue's, the cause could well be the router. Have you tried replicating the issue on another network?
