My jetson TX2 can't connect to wifi

I have been working on jetson TX2 for 4 weeks.
Today after I moved jetson tx2 and my laptop to another desk, I found that mt jetson tx2 can not connect to my lab’s wifi. But both my pc and my macbook can connect to wifi.
I checked the network manager on my tx2, it said that my lab’s wifi is out of range. Can anyone help me solve this problem? Thanks

If you already connected the antenna, then maybe it is just really out of range…
