WiFi / DHCP troubles after Macbook Pro sleep? (Early 2015 Retina, Monterey) - eviltoast

Hi guys,

So I’ve been experiencing a lot of issues lately with my Macbook losing WiFi after waking up from sleep. I have no idea what is causing it, it was never an issue until about 3 weeks ago when I started using an external monitor and a dock (but have no idea whether it is correlated).

Tried all the tricks I read online: Reset SMC, PRAM, remove all saved WiFi networks and locations, create new ones, reset router… The only thing that seems to fix it is if I reboot the Macbook.

I fiddled around with the Network settings and set the macbook to use “DHCP with Manual address” and that seems to give me partial connectivity: some apps will work, some won’t. Some websites will load, some others won’t.

Does anyone have a permanent fix for this? It’s incredibly annoying that I step away from the workstation for 5 minutes, come back, and find that I have no internet again.
