Draytek 2750n and BT Infinity

We've been worrying about the Huawei Openreach Infinity modems because of the tales of woe in the BT Community forums. They overheat and can only be replaced by BT Openreach Engineers. This means you have to wait for an Engineer to turn up to replace the modem. A 2 minute job. As an insurance policy, we decided to get a Draytek Vigor 2750n. I cannot fault it. There are excellent setup instructions here:

WAN->Multi-VLAN->WLAN VLAN ID = 101

All you need to know on top of this is that the BT Infinity Username password combination is:

PPPoE
Username: bthomehub@btinternet.com
Password: One blank space

It doesn't work with nothing there and it didn't work with BT. I had to use one blank space. It then connected first time.

Gallery of the install photos found below. The Openreach modem has been left on the wall for failover purposes. It is not powered up.
