Can't stream through Airport Express
I have a MacBook Pro 2017 with OS Monterey 12.6.3. and an Airport Express 2nd generation firmware 7.8.1. It has always connected to the Airport without any trouble but now it suddenly stopped. My wife's Macbook Pro and both our iphones can still connect to the Airport Express without any trouble. Also my Macbook can see and communicate with the Airport Express through the Airport configuration program. The only thing that doesn't work is streaming music.
Internet is through another router, the Airport Express is wirelessly connected to this router. On the Airport Express DHCP is on, IPv6 is set to automatic (also tried link-local), Ipv6 mode is native (also tried tunnel)...nothing seems to work. Does anyone have any idea?
Thanks
MacBook Pro 13″, macOS 10.12
