Man of Honour
If you want advanced stuff then don't look for it in an ISP-supplied router. They are designed to keep the amount of support calls to a minimum and compete on areas that marketing deem important (whether they are beefy enough for the connections, is the Wi-Fi any good etc.), not for people who like to tweak things.
+million and moreI'd like to see an ISP-supported device with a bridge mode to be fair - ISP handles making sure it plays nicely on the network, keeps the firmware up-to-date etc, then that device becomes the demarcation of responsibilities when troubleshooting.
The BT Business Hub will do this, it would be nice if they made the feature available to home users as well.
Does this still require the fibre modem? As in the main white box the fibre connection goes into, then this connects to that?
