Hi, if I understood you post correctly, are you trying to use a modem from Virgin Media with your Archer MR600?
If so you can follow the instructions below.
So basically you cannot use the same ip pool / range as your Virgin Media for your Archer MR600.
For example:
If your Virgin Media Router ip is 192.168.1.1 (leave the ip at default), you need to change the ip address of your Archer MR600 Router to 192.168.2.1 or 192.168.3.1 an so on or an ip to your liking.
1. Unplug your Virgin Media cable from your router
2. Open the Archer MR600 Interface by typing the router's ip 192.168.1.1 (default)
3. Go to Advance > Network > LAN Settings > IP Address and change the default ip of your Archer MR600 router and leave everything else default. The next time you want to access your Archer MR600 Router. Type in your new ip.
4. Make sure the router is set to Wireless Router Mode. Go to Advance > Operation Mode > Wireless Router Mode.
5. Plug your Virgin Media Cable back into the MR600 WAN port and you should be able to access the internet.
6. (Optional) You can log in to your Archer MR600 then go to Basic > Internet and change to Static IP if you prefer, by default it should be set to Dynamic.
7. (Optional) If you decided to set it to Static IP and configure your own, follow the instructions below.
For example:
1. If your Virgin Media IP is 192.168.1.1
2. Change your Archer MR600 Internet IP to static by going to Basic > Internet or Advanced > Network > Internet and enter the following
IP: 192.168.1.2 (Same IP pool as the Virgin Media Router)
Subnet: 255.255.255.0
Default Gateway: 192.168.1.1 (Your Virgin Media Router IP)
Primary DNS: 8.8.8.8 (If you use Google DNS)
Secondary DNS: 8.8.4.4
Next go to your Network Adaptor Setting on your computer and enter the following, if you want to set a Static IP or you can click on Obtain an IP address automatically if you decided to let the computer configure the IP automatically.
IP Address: 192.168.2.100 (Your new MR600 Router IP pool)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.2.1 (Your New Default Archer MR600 Router IP)
Preferred DNS Server: 8.8.8.8
Alternate DNS Server: 8.8.4.4
Note: If you still can't access internet after following the 5th step, configure your own IP by following the 6th and 7th. Also don't forget to change your IPV4 IP Address to Obtain an IP address automatically when you are following the above steps, if you have previously configured or set your IP to Static IP or you won't be able to access your router or the internet.
Hope this post help you.
