I am thinking of using 4 wlan on RB532 (plus RB502 daughter board), but here's some issues that i am worried about :
1. Could the CPU on RB532 support so many wlan altogether? I have tried using RB532 with 2 wlan and put on a VPN tunnel on it to serve about 1 MB traffic on that tunnel (i am using EoIP tunneling), but the CPU load on it is really high, it's about 20-35% CPU load. If i use 4 wlan on RB 532 (no VPN) can the CPU serve the client? I am planning to put 1 MB traffic to this RB532.
2. Do i need 18v power or 48v power?
Thank you all.
