My use case is a single cable internet connection, and a footprint that needs 2 APs to provide sufficient high-performance coverage.  I would like to provide guest and internal WiFi networks at both APs, so that both will be reasonably fast.

I initially set up mesh mode according to wiki directions, and have it mostly up and running.  I can ping from a machine connected to the second router, across the mesh, to the first router and out to the internet.

The problems I am experiencing are that

1) the second router by default isn't set to forward DNS requests to the first router, so I have to configure each of the interfaces manually to supply the IP of the primary router as the DNS server

2) both routers try to maintain DNS for home.lan and do not exchange information. 

3) the Macs in the household go a little nuts when they change networks as they seem to detect the mdns repeater as a conflict when trying to assume ownership of the hostname on the new network.  My Mac's hostname has changed repeatedly to avoid the conflict and is now tesla-71.local. 

Is mesh the right way to go here?  What are best practices for tackling these issues?

Thanks,
