Wifi stops and is blocked after boot

[Zopss]

Hello,

for a couple of days I have experienced the following issue:
For a couple of minutes after boot my Wifi is working fine, but at some point at least 5 minutes into a session I can't access websites anymore although the Wifi-Symbol iis still showing a connection. When I click on the Wifi icon in the panel it immediately turns red and I have to reboot the whole system, as restarting the network manager in the Terminal has no effect.

Hello Zopss and welcome to Linux Mint Forums,

You can try this command in a terminal see if it unblocks the card

Code: Select all

rfkill unblock all

If it does reboot and see if it blocks again if so we go from there.
