Hope someone can help, i would like to run a second router from my original HH5 as a ddwrt router(E200), basically as a second network within my home.
Can somebody help with a step by step(very simple) ?
I know the two are compatible, but really am lost with how to do this?
As the HH5 is a modem/router, you cannot add another NAT router to your network, assuming that you are on Infinity, and do not have a separate Openreach modem
All you can do is to add an additional wireless access point, or additional Ethernet connections.
You may be able to use the E200 as a basic wireless access point by connection one of its LAN ports to one of the the HH5 LAN ports, changing its IP address and turning off DHCP.
To be honest, its much simpler to use a broadband extender with inbuilt wireless, it also saves running any extra cables.
I have read that you can set up another router running from the main router(HH5), and set it up as a second network, for dedicated traffic, like a business network and keep the HH5 for personal traffic?
I cannot see how that could be possible, as you only have one Internet connection and a basic NAT router. An additional wireless network could be given a different SSID and password, but it would still be on the same subnet, and there would be no isolation.
If you are looking to setup a Guest network, then some wireless routers do have this facility, but they would have to be connected to a modem, if you are using Infinity.
As fas as a business network is concerned, you would not be allowed to run a business on a BT Residential account anyway, as its forbidden.
