I gained 2 models of this access point for my modem router Wifi (v g) could not cover my whole house and going particularly badly upstairs (presumably the thickness of the walls and cumulative ceiling). Suddenly, I had problems connections and appalling rates. My problem was solved thanks to these great features simply. The configuration of the first access point is done in 5 minutes, thanks to an excellent wizard (Windows only) provided by Trend. To enable relaying the signal, simply activate that option and enter the MAC address of the other case (the address is written on one side of the case, could not miss it). For the second case, it's a little more difficult because the documentation is not very detailed. We must proceed in the same way as your first case (except that it is better to disconnect the first, if not, once the relay activated, the signal starts to cycle through your equipment). It's the only gripe I have about this case. Warning, this model does not ADSL modem (usually, your ISP provides), but trendnet released the same model with ADSL modem - firewall included. Would recommend to anyone that the CPL (Powerline) is not satisfied and have signal strength problems and / or flow.
