R7800 is giving wrong gateway to wifi device

[Knzych]

I bought a R7800 yesterday,
It works well on the lan connection.
However, there is a weird problem on the wifi connection,
the default gateway was set to 192.168.1.1,
But those wifi connected device mostly getting 192.168.30.1 as default gateway and lead to no internet connection to those device.
Even i hard mapped those device ip to 192.168.1.x
It still getting 192.168.30.x ip
Do anyone know how to solve this problem?
i have already updated to the most recent firmware.
Thanks a lot.

but still thanks for your help.

Its due to the secureNAT from softether

hope anyone who encounter this issue can solve through turning it off

do you have a modem-only or a gateway (modem+router) in front of the R7800?

Can you explain what that does? It might help someone who hits a similar issue.

What is it for?
