Default Sm-p607t ud 2014 wont pick up tether wifi

HELLO, i just bought a sm-p607t ud abd it works lovely but i only have a 1Gb plan, i was planning on using tether but it seems not to pick the wifi tether from my note 3. they must have some sort of way to block those aps, is there a way around i dont think they have costume roms that work for this tablet please help. btw i tried both the stock wifi tether and 3rd party it picked up none except regular wifi from routers.
