Contact sensor not responsing 30’ from base

Installing new Ring Kit Having issue with one of the contact sensors It synced to the system/app etc fine when near the base But as I walk away from the base with it it stops recognizing that it is opening or closing once I am about 30 feet from the base. I added the range extender between the base and where I’m installing the sensor. Still cutting out at the exact same spot. Installed the extender about 10 feet from the base between base and sensor location. Trying to install the sensor at my garage. Base is about 10 feet from the exterior wall and extender is within a foot of the wall Specs say devices can be within 250 of base and then another 250’ of extender. Only trying to go about 130-140 from base and 120-130 from extender
