Is there no repeater mode for r195w routers?
Yes , it is there.
Please see attached images.
So the r195 that is repeater mode connects to main AP/router(r195w) with the 5GHz channel, so all clients that connect to either the main AP/router or the repeater only connect using the 2.4GHz since the 5 is using to connect AP and repeater?
Also, on the repeater does one disable the lan dhcp so the IPs are dealt out from the main AP/Router?
Even if you have configured repeater on 5GHz, you still will be able to connect clients to it .
If you have configured Repeater WAN in bridge mode , you will get IP from Base AP . Better to disable DHCP on Repeater .
If you have Repeater WAN in NAT mode , you will need to keep running DHCP on repeater , but change default IP pool on Repeater from 192.168.11.0/24 to something else .
Below are few article to help you with configuration .

If I put the repeaters ssid and password the same as the main AP can we expect devices to connect seamlessly from main AP to repeater?
