Hi everyone.
I’ve recently been having some issues with the Wi-Fi connection on my MacBook Pro 9.2 mid-2012. For a few days now, the card seems to be randomly dropping packets and often gives me errors with DNS resolution or web page loading.
I’ll leave you with some details, but if you can help me, please ask me what you think might help me identify the problem.
lspci -k | grep -A3 -i network

These are two ping attempts made back to back. The first failed, but the second worked immediately.
❯ ping 1.1.1.1
ping: Do you want to ping broadcast? Then -b. If not, check your local firewall rules
❯ ping 1.1.1.1

The card has always worked perfectly despite its age.
Power saving is disabled.
It would be great to have some help.
Thanks!
