Cascade Router

Hello everybody,
I cascade Netgear DGND3700v2 to a modem of my provider (LAN to LAN). I followed this steps:

1) Adapt DHCP range (for main modem in set from 192.168.0.2 to 192.168.0.254 and its IP is 192.168.0.2, while for second modem, the DGND3700v2, is  the IP is 192.168.0.1)

2) Disable DHPC, firewall and NAT to second modem (this featureas are active on first modem).

3) Change DNS, which match to first router IP

All work properly, I'm able to surfing web. However, I 've a some problem:

1) Router time isn't correct: from advanced > Security > Schedule I'm not able to set time manually. 

2) I' ve problem with "turn off wireless signal by schedule" functions, it's inactive. 

I attach two image.

Thanks for all replies.
