TomatoUSB

Hi, I'm new to tomato and this site. I have experience setting up router for security but not vpn's or tomato. i'm tech savy but am not at and IT level.

I bought a netgear nighthawk R7000 and loaded the initial tomato file and then the latest "trx" vpn file. i had the interface and all was fine but i didn't know mush about tomato so i decided to return to the neatgear firmware. i have the R7000 backto ofw file.

i exited out of the browser and i don't know how to get back to the gui to load the "R7000-back-to-ofw" file. what ip address to i use to sign in to tomato and get interface to show up. 192.168.1.1 use to work now it doesn't
Thanks
