I just received a Pi 4 2GB today. Everything is working great except for the wifi. I'm connected to a 5ghz AC network. It connects fine and the connection never disconnects, but exactly every 1 minute the bit rate will drop from 200mbps to 25mbps and stay there for ~5 seconds then return back to 200mbps. For my use case, I need the high bit rate to be maintained and the drops are killing me. No other device on my network is experiencing this problem. Ethernet works perfectly.
Any ideas what might be causing this issue?
- Running latest Raspian 32 bit with latest packages installed
- Tried switching the channels my wifi access point is broadcasting on
- Tried disconnecting every other device on my wifi network
