I have two routers at home, one provided from the ISP and the other from me personally. I use second router as extender, so the second router connect to my main router wirelessly and extend the wifi signal. The problem is when i connect to my second router, i am able to open my main router ip address (192.168.1.1) this IP we use to configure the router to change wifi password and etc. How to block second router from accessing my main router IP address ?

Main router is Nokia G 240W F
Second router is TP LINK TL WR840N (Operation mode is WISP)

UPDATE

I use access control option on my 2nd router and create new rule, set host ip range from 192.168.0.2 - 192.168.0.254 and i add 192.168.1.1 to target with everyday schedule. And yes it worked.
But i have question, by putting 192.168.0.2 - 192.168.0.254 to host ip range, does it mean i blocked every device? is there more than 254?
Sorry i am really new about this. I hope i blocked all device.
No, on a /24 subnet (255.255.255.0) you have a maximum address space of 256, you can not use .0 or .255 (.255 is the broadcast address and as such anything sent to that address is received by all devices in the subnet.
How is the 2nd router setup? If possible, you put the 2nd router on a different subnet, like 192.168.0.1 and let it hand out IP addresses in the x.x.0.x range, then anything connecting to it's WIFI would get a IP in the x.x.0.x range and not be able to access anything in the x.x.1.x range.

The 2nd router address is 192.168.0.1 . Is it possible to use 2nd router feature to block 192.168.1.1 ?

The last time I did this it was super easy. I plugged my PC/laptop into the 2nd router and went into the settings. I told it it was an AP extension and gave it the other network settings. I think. I then exited and told it to reboot. After that it worked as an extension. See if your router has something similar. I was using an ancient Dlink I had laying around.
