Replaced Drayek Vigor 120 as modem for ASUS RT-N66U Wireless Router, 8 Aug. 2013
We needed to rethink our slow BT Home Hub to get a signal at the other end of the house. So in August 2012 I bought a Drayek Vigor 120 as a modem situated where the BT line came into the house, and took an RJ45/Cat 5 cable further into the house and attached an ASUS RT-N66U wireless router, with an ASUS EA-N66 as a repeater / range extender in line of sight, but serving the 'radio' shadow' caused by a large brick chimney. This combination got a strong wireless signal all over our house and improved our Broadband speed. We were very pleased with the result. However, after 6 months or so we found that we needed to re-boot the Draytek modem on an increasingly regular basis. It also got hot enough to brown the white gloss paint on the window ledge on which it sat. Last week, the ASUS RT-N66U reported that a cable wasn't attached to the modem. On further investigation we concluded that the Draytek modem was terminally failing, at just under 12 months old. Looking at reviews here on Amazon suggested buying the TP-Link TD-8817 modem router, but for £1 more I bought the TD-8840T, which has 4 LAN ports rather than just one. At £15, you can't go wrong, and its a small price to pay to sort out our household internet service -its surprising how much we rely on it. The TD-8840T was straightforward to get up and running, but I still needed to connect the ASUS wireless router. The ASUS unit didn't seem to like the fact that the TP-Link Modem was also configured as a router and was taking 192.168.1.1. After further research I found out how to configure the TP-Link device simply as a modem. On the modem control panel, click on Network, then LAN Settings. In the ATM Setting section, for a BT Broadband ISP account, set VPI to 0 and VCI to 38, and in the WAN Service Setup section choose 'Bridge' from the drop down selection list for WAN Connection Type. Then sign in to the control panel for your ASUS wireless router, which will now be at 192.168.2.1 and sign in to your BT Broadband account as a PPPoE connection type. You can then complete your Wireless setup. In hindsight, I could have saved £1 by buying the smaller TD-8817 with only the one LAN port, but they are otherwise very similar units. The Broadband speed checker seems to indicate that download and upload speeds are just as good as with the Draytek unit.
