RB951-2n thinks it's Jan/01/1970 unless I use SNTP

So everytime I reboot the router, have power outage, etc.. The device is thinking it’s Jan/01/1970 again even after setting the clock.

Is there something I can do other than use SNTP ?

That’s the normal behavior, the routerboard does not have a battery inside to keep the memory up. Every time you reboot you need to use SNTP or NTP client to synchronize time and date.

OK. Should this use much bandwidth ? I’m on a 10 GB cap.

Oh no, not at all. It’s just very small packets. I don’t actually know how much but it is pretty small. You can monitor udp port=123 on the wan interface if you really want to know how much it uses.

I have WLAN bridged and interfaced disabled so LAN can work. Since I don’t have anything wireless currently.

From the steps at : http://forum.mikrotik.com/t/how-do-i-turn-off-wireless-on-rb2011uas-2hnd-in/60455/1

Actually in winbox it’s even easier. Open “IP” → “Address”. Double click the address “192.168.88.1” and change the interface from Wlan1 to Bridge-Local. Then you can disable wireless and LAN will work
