Double NAT, SPA122

Hello,

 

When connecting Smartrg808 Wi-Fi modem directly to SPA122 it works fine .But when connecting SMartrg808 to another Wi-Fi router then to SPA122 it doesn't work with no dial tone.

 

Default gateway of Smartrg808 is 192.168.0.1

Default gateway of Wi-Fi router is 192.168.11.0

 

Even after removing the Wi-Fi router and connecting directly to SMARTRG808 modem , SPA122 was getting 192.168.11.7 , I tried IVR reset and restarting BOTH till it got 192.168.0.11 with a dial tone 

 

And when I replaced the Smartrg808 with Non-Wi-Fi modem Technicolor TC4350 , SPA122 worked fine (Technicolor to Wi-FI router  to SPA122).

 

I wonder why It doesn't work when the Wi-Fi router was in the connection , What can I do to use the Smartrg808 with the Wi-Fi router . 

And why it worked with Technicolor TC4350 and not Smartrg808

 

Thank you
