Why console is not available？Maybe you could find some ARP scanner software, but I think console is ok.

470T+ is not a VPN router......Maybe it's not working, you need a VPN router like 6120 or something what.... I asked for support from tplink, they said the PPTP in WAN setting is for Russian Dual...

5120 is a load balance router...the bandwidth of several WANs could be balanced....That's a few WANs into 1, in my opinion.

You mean, use PPPoE on 470T+?? 470T+ is wired router, how to connect your wireless network to 470T+......wanna help, but don't understand.

any hint from the R488?

Cannot change dynamic to static,it's strange....Mine is OK....
