models: RT-N16 / e4200v1 firmware: tomato Firmware v1.28.0497 MIPSR2-Toastman-VLAN-RT-N K26 USB VPN-NOCAT I'm trying to save bandwidth stats to the usb, network, jffs, or custom location and it all doesn't work. When I try to backup it gives me error 500. I assumed that its broken if I try to download it. So I left it running for 4 days but no stats saved. When I switch it back to ram the bandwidth stats download just fine. Is this a bug or I'm doing something wrong?
