Wifi stops working on Mint 19.2 completely

Post by iRiKi »

Sorry to bump in, but I have the exact same issue, but on 19.2. - Cf. thread: Internet occasionally stops working on Linux Mint LMDE 4

I only use WiFi, and maybe once a day the network goes down mind you it's not "the internet" but all network, meaning I cannot reach (ping, telnet) other local hosts on the network.

Basically the fix is to toggle the "Wireless" button in NetworkManager, but the issue is, I don't know if I'm disconnected until I try to use the network and everything fails, meaning the NetworkManager wifi icon stays as it is connected. Not good.

I know how to fix the issue when it occurs, but what I'd really like to do is to troubleshoot the issue down to the driver level in order to detect what's happening. Can anyone shed some pointers here?

Many thanks in advance.

Reason: split off from an LMDE4 thread, where the issue was not the same. https://forums.linuxmint.com/viewtopic.php?f=249&t=328635
