- Comcast XFINITY (87.2Mbps/5.72Mbps)
- 2015 iMac (21.5″, 1.6 GHz Intel Core i5)
- 2019 Netgear Cable Modem CM500
- 2009 AirPort Extreme (MC340LL/A Model No. A1354)
JamKazam Issue: No audio
Disconnect AirPort Extreme and go direct from Ethernet to Ethernet (Netgear to iMac). For some reason, the AirPort Extreme auxiliary Ethernet ports are not a true bypass, but conflict with JamKazam.
