Replacing BT Infinity HomeHub with a better router

I needed to replace my BT Infinity HomeHub3. It’s a terrible router. I won’t go into it here, but a quick Google will show you the common problems.

Fortunately it’s relatively easy to  to change it for a better one. There is one little pitfall to mind out for, more of that in a minute.

First of all you need to buy a cable router, not one with a built in modem (although in theory if you already have one of these you should be able to set it to “bridge” mode to sidestep the built in modem). After a little research I bought an Asus RT-N56U. I whipped out the HomeHub, popped the the Asus and … nothing. Did it again. Nada.

I spent far too long messing around with settings, switching back to the HomeHub to get online to find out what the settings and username / password should be. I even left everything unplugged overnight to make sure  there were no gremlins in the machine(s). No joy.

I finally discovered the solution. Do not use the BT supplied ethernet cable that links the modem to the HomeHub to connect the modem to your new router.

No really, that’s it. It looks like a standard ethernet cable, but isn’t.

So all you need to do is:

  1. Unplug the modem for two minutes
  2. Discard the BT ethernet cable with red connectors
  3. Connect the modem to your router with a new ethernet cable
  4. Switch everything on
  5. Set up your router according to the instructions
  6. The username is – no password is needed

Happy days! :-)
