I'm stuck with very slow ADSL speeds so am trialing adding a 4G MR600 to my VR2800 home network. I'm running an ethernet cable between the two devices on the LAN/WAN ports and I now have much better download and upload speeds with the 4G modem. But there are some issues I'd be grateful for advice on.

I'm retaining the VR2800 as I have a number of 1080p video streams (IP security cameras and a TV streaming box connected by WiFi via a network extender, 2 x NAS serving HD video and audio) and the VR2800 has much higher bandwidth than the MR600. I have turned off the MR600 WiFi so all my WiFi devices connect to the VR2800. My Windows 10 desktop and both NAS devices are connected to the VR2800 via ethernet cables.

• Is it possible to have the VR2800 set up as the sole DHCP server?
• Both the MR600 and VR2800 web interfaces have the same IP of 192.168.0.1. Subnet mask for both is 255.255.255.0. How can I assign different IP addresses to get web access to both devices?
• I previously used a Raspberry Pi as a network wide ad blocker using Pi-Hole with a static IP. How would I configure this with both the MR600 and VR2800 running together?

Thanks for any wisdom you can pass on.
