I’ve been having an issue with my Peplink Balance 20 since I’ve gotten it, but now I am implementing WAN2 failover and would like to correct the problem.
Basically when I have WAN2 trying to connect (router is find if WAN2 is in standby) and the AP controller is active, the router’s CPU goes up to 100% and hangs at the UI. Resolves with disconnect of WAN2 and/or APs or reboot of router with WAN2 disconnected.
This was a second hand purchased device.
Maybe related issue, but I’ve also noticed that when my NAS starts syncing large files to another location via site-to-site VPN, it can also cause the CPU to go up to 100%. Temporarily dealt with by thottling at the NAS level, but would like to avoid having to throttle. (1 Gb/s Fios on this side, slower 70 Mb/s on the remote site, throttle set at 2MB/s to stop CPU from maxing out.)
