RV042 router; WAP121 wap; COMCAST ISP.
MTU set to AUTO, I cannot connect to live;
Set it to MANUAL (eg 1458) I can connect. But with it set to manual my overall internet connection rate drops dramatically, to sub-1 Mbps. If I leave it on auto my connection rate is around 45-Mbps but no Live connection. Multicast Pass is enabled.
This is driving me bonkers. Thanks to anyone who can assist.
